DETAILED DESCRIPTION OF THE INVENTION

(13) The embodiments of the present invention will be described with reference to the accompanying drawings and below description.

(14) Referring to FIGS. 1 and 5, a urine absorbing device 10, 100 suitable for a female and male, respectively, is depicted. The device 10, 100 contains a biodegradable receptacle 1, 11, lubricating material 2, mesh covering 3, cylindrical body 4 and a withdrawal cord 5.

(15) The body 4 has an insertion end, a withdrawal end, a longitudinal axis, and an outer surface. As depicted in FIG. 1, the body 4 may contain a mesh covering 3 on or around the outer surface. Although shown as generally straight and cylindrical, the shape of the body may be straight or non-linear that curves along the longitudinal axis. A spiraled indentation into cylinder, e.g., may increase intra-urethral wall surface tension by increasing device surface area.

(16) Other shapes are possible, such as those depicted in FIGS. 7B-7C. The bodies 304 may include shapes having a cross-section that can be described as rectangular, triangular, trapezoidal, semi-circular, hourglass-shaped, S-shaped, or other suitable shapes. The outer surface of the can be altered to have a non-uniform surface topography.

(17) The “outer surface” refers to the visible surface of the body, which may be compressed and/or molded before use and/or expansion. At least a portion of the outer surface may be smooth, or alternatively may have ribs, spiral ribs, mesh patterns, etc., or other topographic features.

(18) The body 4, 304 is comprised of absorbent material that expands upon contact with urine. A wide variety of liquid-absorbing materials used in absorbent articles are suitable, such as rayon, cotton, or comminuted wood pulp which is generally referred to as airfelt. Examples of other suitable absorbent materials include creeped cellulose wadding; meltblown polymers including conform; chemically stiffened, modified or cross-linked cellulosic fibers; synthetic fibers such as crimped polyester fibers; peat moss; tissue including tissue wraps and tissue laminates; or any equivalent material or combinations of materials, or mixtures of these. Preferred absorbent materials comprise cotton, rayon (including tri-global and conventional rayon fibers, and needle punched rayon), folded tissues, woven materials, nonwoven webs, synthetic and/or natural fibers.

(19) The body 4, 304 may preferably be constructed of rayon or cotton or some combination of these. Suitable cotton material includes, long fiber cotton, short fiber cotton, cotton linters, T-fiber cotton, card strips, and comber cotton. Preferably, the cotton layers should be a scoured bleached cotton absorbent with a glycerin finish, a lemolin finish, or other suitable finish.

(20) As shown in FIGS. 4 and 6, the body preferably contains a central absorbent core having a first end, a second end disposed opposite said first end, and a side surface extending between said first end and said second end, wherein said first end corresponds to an insertion end of said device, said side surface being oriented in a direction generally parallel to a longitudinally-extending central axis, said central absorbent core being constructed from an absorbent material compressed to a self-sustaining form; and a withdrawal cord joined to said device and extending therefrom.

(21) As used herein, the term “longitudinal axis” refers to an axis A-A that passes through the center of the device, as shown in FIGS. 1 and 5. A portion of the device may be asymmetric about the longitudinal axis, such as when the withdrawal end region is twisted open from the initial shape of the rest of the device in a funnel shape (such as a “fin shape”). Further, the longitudinal axis may be linear or non-linear.

(22) As used herein, the term “radial axis” of a device refers to an axis that runs perpendicular to the longitudinal axis of the device, shown as B-B in FIG. 1.

(23) The length of the device can be measured along the longitudinal axis from the insertion end to the withdrawal end.

(24) The withdrawal cord 5 may be attached to any suitable location on the device. The withdrawal cord, in one embodiment shown in FIG. 4, may be attached to the outer surface of the insertion end of the body. Alternatively, the attachment may be at the first end of the central absorbent core in one embodiment, or may be at the second end of the central absorbent core in other embodiments. In additional embodiments, multiple cords may be attached to the body and/or core allowing for both withdrawal and post-insertion manipulation of the absorbent device.

(25) The withdrawal cord 5 may be made from any suitable material known in the prior art and may include cotton and rayon. In addition, the withdrawal cord 5 can take other forms such as ribbons, loops, tabs, and the like. The withdrawal cord may be integral with the body. The withdrawal cord 5 or a region of the withdrawal cord 5 may be treated to be non-absorbable, absorbent, or hydrophilic. The withdrawal cord 5 may be attached in any suitable manner known in the art, including suturing, adhesive attachment, bonding, thermal bonding, or combinations thereof.

(26) The withdrawal cord 5 may be attached along the entire length and/or one major surface of the body and hang free from one end, such as the withdrawal end.

(27) The term “attached”, as used herein, encompasses configurations in which an element is directly secured to another element by affixing the element directly to the other element; configurations in which the element is indirectly secured to the other element by affixing the element to intermediate member(s) which in turn are affixed to the other element; and configurations in which one element is integral with another element; one element is essentially part of the other element.

(28) In certain embodiments, the withdrawal cord 5 may be attached to the body using any suitable adhesive. Such adhesive may extend continuously along the length of attachment or it may be applied in a “dotted” fashion at discrete intervals. Alternatively, the cord 5 may be attached by stitching. Such stitching may use cotton or rayon thread. Other attachment mechanisms include thermally bonding, fusion bonding, or any other suitable means known in the art for joining such materials.

(29) As shown in FIGS. 1 and 4-6, the device may contain a lubricating material 2 at the insertion end.

(30) Any lubricant suitable for urological procedures is contemplated. In typical urological procedures, before inserting a device into the urethral orifice during examination or surgery, lidocaine jelly hydrochloride or lubricant is applied to the urethral orifice. The lubricating material 2 may be a hydrophilic anesthetic jelly (e.g. lidocaine jelly 1% pr 2%). A preferred lubricant is KY™ jelly. Alternatively, a water soluble lubricant such as SURGILUBE® surgical lubricant sterile bacteriostatic is contemplated. The lubricating material may additionally contain active agents, such as antibiotics, vasodilators, or cancer agents, as further discussed below.

(31) Typically, about 1 to 2 mL of lubricant material will be sufficient. Those of skill in the art can adjust based on the patient and procedure.

(32) The lubricant may be contained in a biodegradable receptacle 1, 11 attached to the insertion end of the body, preferably the tip of the insertion end, as shown in FIGS. 1 and 5. The receptacle 1, 11 is ideally made from a biodegradable or compostable plastic such as PLA (polylactic acid, or its polymers, made from fermented plant starch such as corn or sugarcane) filled with 1 to 2 cc's of viscous lidocaine 2%, or alternatively, a water soluble lubricant such as SURGILUBE®. It is also contemplated that other bio-based plastics such as PGA, PHAs, PBS, PCL, PVA PBAT, starch blends, cellulose esters and their derivatives, and lignin-based polymers may be used as alternatives or in conjunction with PLA.

(33) In certain embodiments, a small force suffices to introduce lubricant 2 onto, and about the device, coating device. Finger pressure is adequate to express lubricant 2 from the biodegradable receptacle 1, 11.

(34) The mesh covering 3 may be hydrophilic coated biodegradable mesh covering measuring approximately 6 mm by 2.5 cm. In some embodiments, the mesh is comprised of polyethylene. Other materials, such as polyurethane, may be utilized for mesh 3.

(35) With reference to FIG. 2, the female anatomy contains a urethral meatus 12, an anterior urethra 20, and a proximal urethra 30. Above the proximal urethra 30 is the bladder 60 and ureters 62. The uterus 40 and vagina 50 lie behind the bladder and urethra, respectively. On the posterior side is the anus 70 and the rectum 80. The device 10 is optimally positioned in the urethral opening and rests in the urethral meatus 12 and anterior urethra 20.

(36) FIG. 3 shows a cross-section of a male pelvis in which an inventive device 100 is inserted. The external male pelvic organs include the penis 110, scrotum 120 and testicle 130. The male urethra is a muscular tube that runs from the bladder 60, through the prostate 105 and penis 110. The pubic symphysis 111 is situated between the bladder 60 and abdominal wall. Like females, the males have ureters 62, a urethral meatus 10 and anterior urethra 20. Males additionally have a Bulbar urethra 104 and bulbo-membraneous urethra 104 between the anterior urethra 20 and the Prostate 105. Seminal vesicle 107 lies on the posterior surface of the urinary bladder 60. The anus 70, rectum 80 and coccyx 90 run along the posterior side. An inventive device suitable for males 100 is positioned in the anterior urethra.

(37) Average diameter for male and female urethral openings is about 4 to 8 mm. The diameter of the absorbent device can be 4 mm, 5 mm, 6 mm, 7 mm and 8 mm. The most commonly sized device is about 5 mm. The French (Fr) scale is used to measure the diameter of urethral catheters, and in turn the diameter of the urethra. The diameter in mm (D) of the urethra is Fr/3 (D=Fr/3). The most common urethral catheters used are 14, 16, 18, 20, 22 Fr catheters, although catheters from 8 to 30 Fr are available. There are some uncommon conditions where urethral diameter may be less than 3 mm or more than 8 mm.

(38) The cylindrical body 4 is preferably about 4-8 mm in diameter by about 3-5 cm in length. In alternative embodiments, there could be opportunity to scale device to the range of French catheter sizes. In contrast, a typical compressed tampon for vaginal use is 30-60 mm in length and 8-20 mm wide. Typical dimensions of a vaginal tampon pledget before compression may be about 40 mm to about 100 mm in length and about 40 mm to about 80 mm in width. Generally, the inventive device material may be about 40 mm to about 60 mm in length and about 50 mm to about 70 mm in width.

(39) Other sizes and configurations are contemplated for other types of mammals, which will be dependent on the species. For instance, it is envisioned that the inventive devices could be adapted and useful for those with incontinent pet dogs and cats. Those skilled in the veterinary arts will have suitable knowledge to adapt the shape and size appropriately.

(40) Because of the need for absorbent capacity, the body 4 of the absorbent devices may be formed from batts much larger in size than the urethral orifice, and compressed to the small size indicated above in order to facilitate insertion. The body containing absorbent material 13 may be compressed in the radial direction, the axial direction, or both, to provide a body 4 which is of a size and stability to allow insertion within a urethra. The body 4 may be compressed in both the radial and axial direction using any means known in the art. While a variety of techniques are known and acceptable for these purposes, a modified tampon compressor machine available from Hauni Machines, Richmond, Va., is suitable.

(41) FIG. 4 shows a cross section of the device of FIG. 1, which is suited to the female urethra. The body 4 contains an outer layer 6, a mesh 3 positioned round the outer layer 6, an intermediate layer 7 and absorbent core material 13 within the intermediate layer.

(42) The outer layer 6 is exemplarily comprised of desiccated cotton. The intermediate layer 7 is comprised of desiccated chitosan or other cellulose bio sponge material.

(43) The absorbent core material 13 may be comprised of superabsorbent polymer (SAP) or nanofiber. In preferred embodiments, the absorbent core material contains hydrogel properties. Although depicted as a plurality of rectangular discrete units, the absorbent core material 13 may take many forms. The absorbent core material may be contained in beads, capsules or sachets that are dispersed throughout the body 4 in a variety of configurations. The beads, capsules or sachets can take any shape. The absorbent core material may also be a SAP crystal, powder, fiber, or gel that is distributed in a homogenous or heterogenous manner.

(44) In FIG. 4, the absorbent core 13 is comprised of a single layer of absorbent material 13 spread consistently along the radial axis. In contrast, FIG. 6 shows a configuration of absorbent the absorbent core that is suited to the male urethra. Due to the longer length of the male urethra, and consequently a suitable absorbent device e.g. 100, it is preferable to disperse the absorbent core along the longitudinal axis.

(45) FIGS. 7A-7D show the interior of an exemplary device 300 having outer layer 304 of the substantially cylindrical body that has depressions of various topography. The body also contains intermediate layers 301, 302; absorbent core 303; and string 305. The outermost surface of the outward layer 304 can contain a mesh as in the aforementioned embodiments. The absorbent core 303 is comprised of two different types of material with one encasing the other. The materials may be the same as those described for FIGS. 1 and 4.

(46) Preferably, the outer layer 301 is comprised of desiccated cotton and the intermediate layer 302 is comprised of desiccated chitosan or other cellulose/bio-sponge material. The absorbent core 303 is super absorbent polymer (SAP). The string 305 is comprised of cotton. The encasing mesh 304 is a polyethylene mesh.

(47) Other examples of suitable depressions can be seen in tampons having a non-uniform topography, such as in U.S. Pat. No. 3,695,270 (Dostal, issued Oct. 3, 1972), and U.S. Pat. No. 4,361,151 (Fitzgerald, issued Nov. 20, 1982) and U.S. Pat. No. 4,328,804 (Shimatani, issued May 11, 1982), U.S. Pat. No. 5,403,300 (Howarth, issued Apr. 4, 1995), U.S. Pat. No. 5,592,725 (Brinker, issued Jan. 14, 1997)), U.S. Pat. No. 5,718,675 (Leijd, issued Feb. 17, 1998). Other tampons include longitudinal ribs on the outer surface, and in U.S. Pat. No. 7,549,982, the tampon has a spiral groove on the outer surface. All such surface topography is contemplated for the urethral devices described herein.

(48) Texturing can be provided through a variety of means, including a multiplicity of texturing elements. Such texturing may be provided by needle punching the surface of the surface to be textured.

(49) Texturing elements may also be configured to transfer fluid from the urethral surfaces to the outer surface of the body and ultimately, to the absorbent core through the use of a density gradient, hydrophilicity gradients, an osmotic driving force, capillarity, or a similar mechanism. Suitable materials for use in such fluid acquisition/transfer mechanisms are rayon (including, e.g., WO 00/06070 conventional, tri-lobed or multi-lobed rayon fibers), polyethylene, polypropylene, polyester, synthetic bi-component fibers, absorbent foams and combinations thereof, all of which fibers may be used either singly or in combination with other fibers are known in the art. Capillary channel fibers are a highly preferred fiber for texturing elements.

(50) FIG. 8 shows an unraveled side view of another device wherein: 407 is super absorbent polymer (SAP) or nanofiber; 406 is desiccated chitosan or other cellulose/bio-sponge material; 404 is desiccated cotton; 405 is cotton string and 403 is polyethylene mesh covering.

(51) In order to absorb urine in an incontinent individual, the inventive devices may be inserted digitally or through the use of known applicators.

(52) Any of the currently available types of tampon applicators may be used for insertion of the absorbent devices of the present invention, with appropriate modification to accommodate the decreased size of the absorbent devices. Such applicators are typically a “tube and plunger” type arrangement and may be plastic, paper, or other suitable material. Additionally, a “compact” type applicator is also suitable. The applicator plunger will push the absorbent device out of the applicator due to the compressed nature of the core.

(53) FIG. 9A is an embodiment of an applicator 900 that may be utilized with the inventive devices wherein 901 is a cylindrical absorbent device having mesh that is housed in the interior of the applicator head 902. Abutted to the withdrawal side of the applicator is a removable plunger 903. A receptacle 904 is disposed at the insertion side of the applicator head 902 and is in fluid communication with an aperture at the tip of the insertion side. The receptacle may be filled with one or more of a lubricant, anesthetic jelly or an active agent.

(54) FIG. 9B shows the receptacle 904 filled with hydrophilic anesthetic jelly. The jelly and device 901 are pushed through an optional notched flange 906 at the aperture of the receptacle and the insertion end of the applicator head 902.

(55) It is anticipated the aforementioned devices are suitable to address incontinence issues in male and female mammals and ED in males. The devices should be changed at regular intervals to avoid infection.

(56) FIGS. 10A-10E show an exemplary method of treating urinary incontinence and ED in a human male patient using a device as shown in FIG. 9A. Referring to FIG. 10A, an applicator, such as 900 containing device 901, is used to place device 901 into a male urethra. The receptacle 904 contains lubricant and, if treatment of ED is desired, a vasodilator such as alprostadil. Alternatively, alprostadil can be impregnated in the device. The tapered applicator tip 906 is placed at the urethral opening with the plunger 903 fully extended out the distal end. As shown in FIG. 10B, the plunger 903 is compressed in the proximal direction, pushing the absorbent device 901, lubricant and alprostadil into the urethral meatus 12. The force used to push the plunger will squeeze the lubricant containing alprostadil in receptable 904 against the applicator head, popping it and coating the insertion tip of the device 901 as it moves into the meatus 12. Alternatively, a patient could pop receptacle 904 between fingers before placing device.

(57) It is also envisioned that the patient could add additional lubricant, as desired, to the insertion tip of the device prior to placing at the urethral opening or squeeze an ampule containing active agent onto the applicator head. It is further envisioned that lubricant could be contained in a first receptacle having a low burst strength and active agent could be contained in a second receptacle that would dissolve or become permeable upon exposure to bodily fluid, such that the agent would only release upon insertion into the urethra or after being in contact with the lubricant for several minutes. This embodiment would be useful for agents that have a tendency to degrade upon exposure to lubricant.

(58) Next, as depicted in FIG. 100, the lubricated device will remain in the meatus and the applicator body 902 containing the plunger 903 within it can be pulled distally and out of the urethral opening. As shown in FIG. 10D, the device 901 will absorb urine and bodily fluid and expand as it absorbs the fluids. As shown in FIG. 10E, when the device feels expanded and full (or after about 6 hours if there is no urination), the string 905 can be used to remove the device 901 from the urethra. The process can be repeated with a fresh, unimpregnated device as the patient desires to control incontinence.

(59) Alternatively, if treating ED, the device containing a vasodilator, i.e. alprostadil, should be inserted about 30-60 minutes prior to sexual activity. The device should remain in the urethra for 5-20 minutes and then be removed by pulling on string 905. Alternatively, a patient may have sexual activity with device remaining in the urethra. A device comprising alprostadil should not be use more than three times a week and the patient should wait at least 24 hours between each use.

(60) FIGS. 11A-11D show a method of treating incontinence in a female using device 10. A plunger similar in design to 900 is used but with the head 902 adapted to accommodate the shorter length of device 10. The tip 906 is placed at the urethral opening with the plunger 903 fully extended out the distal end. As shown in FIGS. 11A and 11B, the plunger 903 is compressed in the proximal direction, pushing the absorbent device 10 into the urethral meatus 12. The force used to push the plunger will squeeze the lubricant in receptable 904 against the head 906 popping it and coating the insertion tip of the device 10 as it moves into the meatus 12. Alternatively, a patient could pop receptacle between fingers just before placing device.

(61) As with the male, it is also envisioned that the patient could add additional lubricant, as desired, to the insertion tip of the device prior to placing at the urethral opening.

(62) Next, as depicted in FIG. 11C, the lubricated device will remain in the meatus and the applicator body 902 containing the plunger 903 within it can be pulled distally and out of the urethral opening. The device 10 will absorb urine and expand as it absorbs urine, as shown in FIG. 11C. As shown in FIG. 11D, when the device feels expanded and full (or after about 6 hours if there is no urination), the string 5 can be used to remove the device 10 from the urethra. The process can be repeated with a fresh, unimpregnated device as the patient desires to control incontinence.

(63) Although methods of addressing incontinence have been shown utilizing an applicator to insert the absorbent devices, it is also contemplated that a patient may easily be able to place desiccated device into urethra alone, without using applicator.

(64) Further, although the foregoing explanations have focused on embodiments of absorbent devices for light incontinence, it should be understood that the present invention may be applied to uses ranging from extremely light incontinence to more severe, by simply changing the materials explained in the embodiments herein.

(65) Another opportunity to use the inventive device is in the ureter. Patients who present with low grade urothelial cancer, or carcinoma in situ of the upper urinary tract often progress to nephroureterectomy because, unlike in the bladder, there is no effective way to allow chemotherapeutic agents to dwell in the ureter.

EXAMPLES

(66) Patient W is a healthy sixty year old female with total urinary incontinence. She is s/p radical robotic cystectomy with creation of orthotopic ileal neobladder 6/2018 and has been incontinent since that time. She wears several pads/day. Although she would like to be sexually active she cannot due to leakage issues. W/u of incontinence revealed no evidence of fistula. She has tried bulking agent in urethra, as well as two f/u operations using rectus fascia to close and support urethra which have failed. She has failed intra-vaginal devices placed to occlude her urethra (Poise Impressa). She refuses to wear an indwelling foley catheter. She refuses abdominal surgery to close urethra and create either continent cutaneous stoma she can catheterize, or creation of non-continent urinary diversion.

(67) Patient X is a healthy 51 year old male s/p radiation therapy to prostate for prostate cancer, s/p radical robotic cysto-prostatectomy with creation of Indian Pouch urinary reservoir for secondary bladder cancer. He is able to catheterize Indian Pouch for several hundred cc but also wears an ostomy appliance for sporatic stomal leakage.

(68) Patient Y is an 87 year old male with total urinary incontinence following radiation therapy to prostate several years ago. He wears a Cunningham clamp to control his incontinence.

(69) Patient Z is a healthy, 40 year old female runner, with significant urinary leakage every time she exercises. She has developed “diaper rash” from incontinence related to pad use, but does not want surgical intervention.

(70) Patient W, X, Y and Z are suitable for treatment with the inventive devices. With sensation of bladder or pouch fullness, or based on a preset timed schedule, e.g. every 6 hours, (if no bladder fullness sensation is noted) the inventive urethral devices could be easily removed, and new GU device replaced.

(71) Patient A is a 43 year old male with progressive ED due to hypertension and diabetes. Viagra and other PDE5 inhibitors work only for a short while. He does not want to use a vacuum pump. He does not want to try penile injection therapy. He has tried MUSE but can't sustain erection. He does not want surgery to place an inflatable penile prosthesis.

(72) Patient B is a 65 year old male who had normal erectile function until he underwent radical prostatectomy for prostate cancer. He also has tried the above mentioned ED treatments without success. He wishes there was a new option to treat his ED, short of proceeding with prosthetic surgery.

(73) Patient C is a 72 year old male s/p radiation therapy for prostate cancer. He has failed available treatment options to improve erectile function. He wishes there was new therapy to manage his ED.

(74) Patients A, B, and C are good candidates for treatment with inventive device. They are motivated men with good performance status who would like to try a new available therapy to treat their ED, short of proceeding with surgery.

(75) Detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms. It will be appreciated that many modifications and other variations that will be appreciated by those skilled in the art are within the intended scope of this invention as claimed below without departing from the teachings, spirit and intended scope of the invention.
