Definitions

[0090] As used herein, the following terms have the indicated meanings unless expressly stated to the contrary:

[0091] The term contoured regions as used herein, means that the regions of the body of the applicator have a shape to them in those embodiments. This would be in contrast to essentially flattened regions.

[0092] The term directionally as used herein means that the object to which it refers has a defined orientation. The term also means that the object is moved or intended to be moved with a defined orientation. For example, the term directionally receiving the pessary means that the applicator device is designed to receive the pessary in a defined orientation and the term directionally expelling the pessary means that the applicator device expels the pessary in a defined orientation for proper placement and positioning within the vagina.

[0093] The term distal as used herein with respect to the applicator device means that portion of the applicator that is intended to receive the object or pessary or into which the object or pessary is inserted. The term distal is the opposite of the term proximal. The term distal with respect to the human female anatomy refers to the end of the vagina closest to the introitus and to the portion of the vaginal pessary that is intended to be oriented towards the distal end of the vagina.

[0094] The term essentially as used herein means that the parameter it defines does not have to be completely as such. For example, essentially flattened means nearly, almost, or primarily flattened.

[0095] The term longitudinal as used herein, is with respect to and parallel or in the same direction as the axis of the body of the applicator, the axis being such that it defines an imaginary line through the body of the applicator. FIG. 1A shows a planar view of the applicator with the longitudinal axis depicted as a dotted line.

[0096] The term proximal as used herein with respect to the applicator device, means that portion of the applicator that is intended to expel the object or pessary or from which the object or pessary is expelled. This proximal portion of the applicator can be defined as terminating in or defining an orifice. The proximal portion of the applicator is the portion intended to be inserted into the body opening or cavity (an orifice) of the human or animal. The orifice of the applicator device is separate from and not intended to be confused with the orifice of the human or animal.

[0097] The term proximal, as used herein with respect to the human female anatomy refers to the end of the vagina closest to the cervix, and to the portion of the vaginal pessary that is intended to be oriented towards the proximal end of the vagina. The term distal refers to the end of the vagina closest to the introitus and to the portion of the vaginal pessary that is intended to be oriented towards the distal end of the vagina.

[0098] The term reinforced as used herein means that the applicator is thicker or has more material associated with it at that area of the applicator. This reinforcement can be achieved by a variety of means, including for example, overmolding the applicator at the desired area with a second material.

[0099] Applicators

[0100] As discussed above, it is an object of the invention to provide a solution for proper positioning of an item that is inserted into the vagina. It is a further object of the invention to provide a solution that allows the item to be stored in a manner that does not distort its shape during storage and which accomplishes temporary compression of the item during deployment, thus allowing it to quickly return to its uncompressed state, particularly when the item is made of a resilient material.

[0101] Disclosed herein are applicators (applicator devices) for inserting and positioning an item inside the vagina. The initial intended use is for inserting and positioning a vaginal pessary for temporary management of stress urinary incontinence. The applicators include a portion which can house a vaginal pessary prior to deployment and a portion which is inserted into the vagina. The portion which houses the pessary is of sufficient width that when it is aligned essentially parallel to the coronal plane of the body, it cannot be easily inserted into the vagina of the average woman without exerting significant force. The portion which is intended for insertion into the vagina is sufficiently narrow such that it can be inserted into the vagina of the average woman without exerting significant force. The force required for insertion is intended to be similar to that force that is required for insertion of commercially available tampon applicators. With the applicators of the present invention, when the narrower portion is inserted, the wider portion will control how deeply the applicator can be inserted into the vagina. The length of the narrower portion will control how deeply the pessary is inserted into the vagina when deployed. The two portions described connect with each other in a way that facilitates compression of the pessary during deployment and further facilitates proper passage of the pessary from the wider portion through the narrower portion during deployment of the pessary. The wider portion can have a length that is significantly less than its width. Such a shape can facilitate proper rotational orientation along the longitudinal axis of the applicator device due to the way that the average user would hold such a shaped applicator device. FIG. 1A is a planar view of the applicator showing the longitudinal axis of the device, represented as a dotted line. Additionally, features such as a groove or channel on the inside wall of the device, or a ridge or protuberance on the inside wall of the device, can help to guide the rotational positioning of the object being inserted.

[0102] In certain embodiments, the applicator device is comprised of an outer member which receives a separate inner member that acts as a plunger to push the pessary in a manner to expel it from the applicator during deployment. In other embodiments, the user can use a finger to expel the pessary from the applicator.

[0103] As discussed above, the term proximal with respect to the human female anatomy refers to the end of the vagina closest to the cervix, and to the portion of the vaginal pessary that is intended to be oriented towards the proximal end of the vagina. The term distal with respect to the human female anatomy refers to the end of the vagina closest to the introitus and to the portion of the vaginal pessary that is intended to be oriented towards the distal end of the vagina. In a normal, intact, female pelvis, the distal end of the vagina is constrained laterally by the pubococcygeus muscles, limiting the width of the vagina. Proximally, the vagina is not constrained laterally by the pubococcygeus muscles and in this area it can accommodate an object of greater width than can be accommodated in the distal vagina. Contraceptive diaphragms and several types of commercially available ring-shaped drug delivery devices are positioned in the wider proximal portion of the vagina when used properly. The present invention can be employed to aid insertion of various products (objects or devices) into the vagina. The invention is depicted here for use with a vaginal pessary for managing and treating stress urinary incontinence. This pessary has a certain shape and is made of a resilient material. During use of the pessary, the narrower, distal, portion of the pessary is intended to occupy a position in the distal portion of the vagina, underlying the urethra. The wider, proximal, portion of the pessary is intended to occupy a position further proximally where its width can be easily accommodated. Insertion of the pessary to the proper depth within the vagina is beneficial for maximum effectiveness of the pessary. See, U.S. Pat. No. 8,323,176 B2, issued Dec. 4, 2012, to Spitz et al., and U.S. Pat. No. 7,981,021 B2, issued Jul. 19, 2011, to Spitz et al., which are incorporated by reference herein in their entirety.

[0104] Insertion of the pessary into the vagina is facilitated by compression of the proximal arms of the pessary prior to, or during, the insertion process. After passing through the distal portion of the vagina, the proximal arms of the pessary are allowed to return to their original configuration and do so because of the resilient nature of the material from which the pessary can be constructed.

[0105] An applicator device as described herein facilitates the insertion of the pessary illustrated herein in several ways. A narrow portion of the applicator device can be inserted into the distal portion of the vagina where the opening of the narrow portion of the applicator device allows the pessary to be expelled from within the device into the appropriate location in the vagina. The length of this narrow portion can be in the range of 0.5 cm to 3 cm. This narrow portion of the applicator device is contiguous with a wide portion that cannot be easily inserted into the vagina of the average woman without exerting significant force. The widest area of this wide portion can be in the range of 3 cm to 8 cm. The illustrations herein depict an applicator device with a widest portion measuring approximately 5.5 cm. When the applicator device is inserted into the vagina using an amount of force that is similar to that force that is required for insertion of commercially available tampon applicators, the wide portion can cause insertion to stop. When the wide portion of the applicator device causes insertion to stop, the point at which the narrow portion is contiguous with the wide portion will be located approximately at the vaginal introitus. When the applicator device is in this position, the pessary can be deployed. When the pessary is pushed toward the vagina, the tapered shape of the inside of the wide portion of the applicator device facilitates compression of the resilient arms of the pessary, allowing the pessary to pass through the narrow end of the applicator device. When the pessary is pushed forward an additional amount, the arms of the pessary are expelled from the applicator device into the vagina. The applicator device is then removed from the vagina.

[0106] Applicators most commonly used for insertion of vaginal products have been cylindrically shaped tampon applicators that are longer in the longitudinal axis than in the horizontal axis. The current invention is such that a part, or the entirety, of the applicator device is a generally tubular structure that can house an object within the applicator device, and this tubular structure has at least one open end through which the object can be ejected. Note that in various embodiments of the present invention, the applicator comprises a housing or region where the device to be inserted can be stored in its essentially noncompressed form. The tubular structure can be configured in a way to create unique advantages over a cylindrical tampon applicator.

[0107] One embodiment of a device 97 is illustrated in top planar view in FIG. 1, FIG. 3, and FIG. 4, and in side view in FIG. 2, FIG. 6, and FIG. 8. A cross-section of the widest portion of the applicator device 97 is shown in FIG. 7 and FIG. 9. As illustrated in FIG. 1, the distal end 6 of the pessary 5 is oriented away from the narrow end 2 of applicator device 97 and the proximal arms 7 of the pessary 5 are oriented towards the narrow end 2 of applicator device 97. The pessary 5 is housed in its natural, uncompressed state with a portion of pessary 5 occupying the wide portion 1 of applicator device 97. Alternatively, the pessary 5 can be placed into the wide portion 1 when the user intends to deploy it. FIG. 3 and FIG. 4 illustrate how a finger is used to push the pessary 5 through the narrow open end 3 of applicator device 97 and into the vagina after applicator device 97 has been properly placed. FIG. 3 illustrates that the finger has pushed pessary 5 towards the narrow end 2 of applicator device 97. FIG. 3 further illustrates compression of the resilient arms 7 of the pessary 5 which has been facilitated by tapering of the inside of applicator device 97 from its area of widest cross-section 1 towards its narrow portion 2. In FIG. 3, the compressed resilient arms 7 of the pessary 5 have entered the narrow portion 2 of the applicator device 97. FIG. 4 illustrates almost complete deployment of pessary 5. FIG. 4 further illustrates that the resilient arms 7 of the pessary 5 have exited the open end 3 of applicator device 97 and have returned to their original uncompressed state.

[0108] FIG. 5 illustrates reinforcement of an area 11 of applicator device 97. FIG. 5 illustrates the reinforced area 11 as including a segment of the wide portion 1 of applicator device 97 and all of the narrow portion 2 of applicator device 97. Alternatively, the reinforced area 11 can include only a segment of the narrow portion 2, or it can include a segment or all of the narrow portion 2 and none of the wide portion 1. Reinforcement of the reinforced area 11 can be accomplished by thickening the walls of applicator device 97 in the reinforced area 11, or by addition of another material as an overlay or insert. FIG. 5 further illustrates that the inside wall of applicator device 97 and the outside wall of applicator device 97 may not be parallel. A specific tapered configuration of the inside wall of applicator device 97 as it transitions from the wider portion 1 to the narrower portion 2 of applicator device 97 can be beneficial for optimal compression of the pessary 5 as it is deployed. A different tapered configuration of the outside wall of applicator device 97 can be desirable to reliably limit how far the applicator device 97 can be inserted into the vagina.

[0109] FIG. 6 and FIG. 7 illustrate a groove 8 or channel 8 on the inside of applicator device 97. The groove 8 or channel 8 is of an appropriate size to accommodate the resilient arms 7 of pessary 5 to guide pessary 5 through applicator device 97 during deployment of the pessary 5.

[0110] Similarly, FIG. 8 and FIG. 9 illustrate protuberances (i.e. protrusions) 9 on the inside of applicator device 97. The protuberances 9 are an appropriate size and spacing to accommodate the resilient arms 7 of pessary 5 to guide pessary 5 through applicator device 97 during deployment of the pessary 5. These protuberances guides can help maintain proper rotational positioning of the pessary 5 during deployment.

[0111] Another embodiment of an applicator device 98 is illustrated in top planar view in FIG. 10, FIG. 12, and FIG. 13, and in side view in FIG. 11. As with applicator device 97, a finger is used to deploy pessary 5 with applicator device 98, as illustrated in FIG. 12 and FIG. 13. Applicator device 98 is constructed of 2 separate materials, as illustrated in FIG. 10, FIG. 11, FIG. 12, and FIG. 13. The proximal end of pessary 5 is housed within a portion 12 of applicator device 98 sufficiently strong to maintain its general shape throughout the process of deploying pessary 5. This portion 12 can be constructed of various materials such as a cardboard material or molded paper slurry. Preferentially, this portion 12 is constructed of a plastic resin. The distal end of pessary 5 is housed within a portion 13 of applicator device 98 that is constructed of a flexible material, such as paper, and this portion 13 is deformed by the finger that is used to deploy the pessary 5. This applicator device 98 either can or does not, depending on the desired embodiment, include the groove 8, protuberances 9, and reinforcement 11 as described above and illustrated with applicator device 97. FIG. 12 illustrates an interim step during the deployment of pessary 5 and illustrates deformation of portion 13 by the finger. FIG. 13 illustrates almost complete deployment of pessary 5. Portion 13 is not visible in FIG. 13 as it has been pushed entirely inside portion 12 by the finger.

[0112] An additional embodiment of an applicator device 99 is illustrated in top planar view in FIG. 14, FIG. 16, and FIG. 17, and in side view in FIG. 15. The shape and position of a vaginal pessary 5 are illustrated when stored within the applicator device 99 and during deployment of the pessary 5. In this embodiment of applicator device 99, a plunger 4 is illustrated. This plunger 4 is used instead of a finger to push the pessary 5 through the narrow open end 3 of applicator device 99 and into the vagina after applicator device 99 has been properly placed.

[0113] FIG. 15 illustrates a thickening 10 of the wall of applicator device 99 where it receives a plunger 4. This thickening can help to stabilize plunger 4 during deployment of the pessary 5.

[0114] In FIG. 14 and FIG. 15 the pessary 5 is illustrated housed inside applicator device 99 in its position during storage. As with applicator device 97 and applicator device 98, the distal end 6 of the pessary 5 is oriented away from the narrow end 2 of applicator device 99 and the proximal arms 7 of the pessary 5 are oriented towards the narrow end 2 of applicator device 99. The pessary 5 is housed in its natural, uncompressed state. FIG. 16 illustrates an interim step in the deployment of the pessary 5. In FIG. 16, the plunger 4 has been pushed partially into the wide portion 1 of the applicator device 99. This has pushed the pessary 5 towards the open end 3 of the applicator device 99. FIG. 17 illustrates almost complete deployment of pessary 5. In FIG. 17, the plunger 4 is shown to be fully depressed into applicator device 99. FIG. 17 further illustrates that the resilient arms 7 of the pessary 5 have exited the open end 3 of applicator device 99 and have returned to their original uncompressed state. This applicator device 99 either can or does not include, depending on the desired embodiment, the groove 8, protuberances 9 and reinforcement 11 as described above and illustrated with applicator device 97.

[0115] FIG. 18. illustrates applicator device 99 when it has been properly placed in the vagina. For illustration purposes, the applicator device 99 that is illustrated in FIG. 18 is aligned generally along the sagittal plane of the body, but during actual use, it may be preferentially aligned generally along the coronal plane of the
