DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS
(26) A better understanding of different embodiments of the support may be gained from the following description read with the accompanying drawings in which like reference characters refer to like elements.
(27) While the disclosure is susceptible to various modifications and alternative constructions, certain illustrative embodiments are in the drawings and will be described below. It should be understood, however, there is no intention to limit the disclosure to the embodiments disclosed, but on the contrary, the invention covers all modifications, alternative constructions, combinations, and equivalents falling within the spirit and scope of the disclosure and defined by the appended claims.
(28) It will be understood that, unless a term is defined in this disclosure to possess a described meaning, there is no intent to limit the meaning of such term, either expressly or indirectly, beyond its plain or ordinary meaning.
(29) Any element in a claim that does not explicitly state “means for” performing a specified function, or “step for” performing a function, is not to be interpreted as a “means” or “step” clause as specified in 35 U.S.C. § 112, paragraph 6.
B. Environment and Context of Embodiments
(30) The supports and methods for use herein may be used in various articles including braces, medical devices, clothing, apparel, bags, safety restraints and the like. In a preferred embodiment, the supports and methods are described in connection with orthopedic devices.
(31) Numerous orthopedic devices and components (e.g., subshells and strap retainers) for use therewith are described, with particular focus given to braces and components directed to the knee joint and surrounding areas. The orthopedic device embodiments may serve in protective, preventative or remedial capacities. While the orthopedic device is described within the context of a preferred embodiment directed to securing the knee joint, many of the features described may be extended to orthopedic devices and components that secure other joints and body parts, such as the wrist, elbow, shoulder, ankle and neck.
(32) The orthopedic device embodiments and components for use therewith may be dimensioned to accommodate different types, shapes and sizes of human joints and appendages. In addition, embodiments may be modified to orient principal forces exerted by support systems of the embodiments at any desirable location to secure the brace onto a leg to stabilize the knee.
(33) The knee joint comprises two joints, lateral and medial, between the femur and tibia, and one arthrodial joint between the patella and femur. The primary movements of the knee comprise flexion, i.e., rearward rotational movement of the tibia relative to the femur, and extension, i.e., forward rotational movement of the tibia relative to the femur.
(34) For explanatory purposes, each orthopedic device embodiment or component thereof described may be divided into sections denoted by general anatomical terms for the human body. Such anatomical terms are provided to distinguish various elements of the brace embodiments from one another, but which are not to be considered to limit the invention.
(35) Each of these terms may be used regarding a human leg, which is divided in similar sections with a proximal-distal plane generally extending along the meniscus of the knee between the femur and tibia. The terms “proximal” and “distal” generally refer to locations of the brace that correspond to the location of leg relative to the point of attachment of the leg to the body. The terms “upper” and “lower” may be used in combination with “proximal” and “distal” to connote gradations in-location of “proximal” and “distal.” The location where the brace corresponds to the knee joint is used to generally delimit the proximal and distal sections of the brace.
(36) The embodiments of the knee brace can also be considered to fall within “anterior” and “posterior” sections by an anterior-posterior plane. The anterior-posterior plane generally corresponds to the coronal or frontal plane of a human leg, which lies along the central longitudinal axis of a body. A posterior side or element is therefore behind this anterior-posterior plane, whereas an anterior side or element is in front of the anterior-posterior plane.
(37) The terms “inwardly” or “inner” are commonly used to distinguish the side of the brace that may be directed to the posterior side of the brace and specifically adjacent to the leg of the wearer of the brace. Contrariwise, the term “outwardly” or “outer” are used to denote the side of the brace opposite to the inwardly side.
(38) The terms “medial” and “lateral” are relative terms generally understood as indicating location near the midsagittal plane or midline. Therefore, elements located near the midline are referred to as “medial” and those elements further from the midline are “lateral.” The term “central” is used to denote the area along the midline of a joint dividing and sharing regions of the medial and lateral regions.
(39) In an embodiment of an orthopedic device, regions of the device may fall within the following quadrants: (I) proximal-medial, (II) distal-medial, (III) distal-lateral, and (IV) proximal-lateral. The posterior section of the brace has the following quadrants: (V) proximal-medial, (VI) distal-medial, (VII) distal-lateral, and (VIII) proximal-lateral. Structural members and features thereof will fall within one of the quadrants is specifically referenced in relation to such quadrant, either in its entirety or partially.
(40) The terms “rigid” and “flexible” are repeatedly used to distinguish characteristics of portions of the brace. The term “rigid” should denote that the frame is devoid of flexibility. Within the context of frame members that are “rigid,” it should indicate that they might break if bent with sufficient force. The term “flexible” should denote that features are capable of repeated bending. The term “resilient” is used to qualify such flexible features as generally returning to the initially molded shape with permanent deformation.
(41) The anatomical and characteristic terms described herein are not intended to detract from the normal understanding of such terms as readily understood by one of ordinary skill in the art of orthopedics. The elements of the embodiments described should embrace embodiments that generally correspond to the aforementioned anatomical sections. It is understood that the elements of the brace embodiments described may deviate from falling exactly within the confines of the aforementioned anatomical sections.
C. Various Embodiments
(42) In observing the
(43) The sleeve 12 is preferably short enabling it to be worn as a stand-alone orthopedic device or in combination with a brace, as depicted in
(44) The support 14 may define an arcuate shape or a C-shape, and is flexible to conform to anatomy of a wearer of the orthopedic device 10. The support 14 is preferably adjustable in length such that a first end 17 of the support 14 includes first and second straps 34, 35 removably securable to a surface of the sleeve 12. The sleeve 12 defines a fastener segment 38 arranged to secure to a corresponding connection feature carried by the first and second straps 34, 35.
(45) The patella device 10 includes first and second flaps 36, 37 each having a first end 39 secured to the sleeve 12 and a second end 41 flexibly extending from the sleeve 12. The second ends 41 are arranged to adjustably secure to an outer surface of the sleeve 12 for adjusting a circumference of the sleeve. The sleeve 12 defines a fastener segment 38 arranged to secure to a corresponding connection feature carried by the first and second straps 34, 35. The second end 41 of the first and second flaps 36, 37 secure to the fastener segment 38.
(46) The flaps 36, 37 may be arranged to secure over and onto the first and second straps 34, 35 and the fastener segment 38. Adjustment of the flaps 36, 37 enable circumferential adjustment of the sleeve to assure it is retained on the leg of the user.
(47) The support 14 may define first and second ends 17, 19 each extending toward the first side 13. The first and second ends 17, 19 have first and second straps 34, 35 securable to the sleeve 12. The middle portion 21 of the support 14 is arranged to resist adjustment of the first and second straps 34, 35. The main body 22 forming the support 14 is preferably formed from a resilient compressible material, such as foam, textile, synthetic or natural rubber, polymer and the like. The elasticity or inelasticity of the material forming the support will depend on the application. In the patella device 10, the support 14 is preferably inelastic to prevent the material of the support from significantly yielding to movement of the user's knee.
(48) The support may vary in width and thickness over its length or cross-section. For example, in
(49) Referring to the thickness, the thickness of the main body 22 may vary along the length of the support 14 and over its cross-section. For example,
(50) The main body 22 may be arranged so different surfaces may have varying contours according to desired areas of support and anatomy or other upon which the support extends. For example,
(51) Although exemplary widths, thicknesses and surface contours are described, the support is not limited to the depicted examples, but may include any combination and varying properties taking the examples in consideration.
(52) A stay 18 may be at one or both of the first and second sides 13, 15 and extending between first and second ends 31, 33 of sleeve 12. The stay 18 is preferably within the sleeve 12.
(53) According to an embodiment in
(54) As shown in
(55) The at least one opening 28 may be formed as a slit and define first and second ends 62, 64. The first end 62 may extend past the midline 65 short of a first periphery 61, 63 and the second end 64 is defined by opposed side portions 66, 67 clamped against one another depending on the length of the support 14.
(56) According to the variation in
(57) The tensioning device 26 is preferably secured to the support 14 so actuation of the tensioning device 26 shortens or lengthens a length of the support 14. The a least one cable segment 24, 25 is linked to the tensioning device 26 and cooperates with the support 14 to adjust the length thereof by actuation of the tensioning device 26. The at least one cable segment 24, 25 extends through the thickness of the support 14 and extends from the first end 17 to a second end 19 opposed to the first end 17 such that actuation of the tensioning device 26 adjusts the length of the at least one cable segment 24, 25 to modify the length of the support 14. The support 14 defines at least one opening 28 through which the at least one cable segment 24, 25 extends.
(58)
(59) Various cable types can be used, including but not limited to stranded steel cable with no coating, stranded steel cable with a polymer coating (e.g., nylon coating), monofilament (e.g., nylon), or other suitable elongate elements. In some embodiments, standard conventional shoe laces or textile cords can be used for the cable.
(60) According to the illustrated embodiments, the tensioning device is configured to incrementally provide or release tension to the cable by tensioning. The tensioning device may correspond to a strap tightener assembly for an orthopedic device according to U.S. application Ser. No. 13/739,491, filed on Jan. 11, 2013 and published as U.S. patent application publication no. 2013/0184628 A1 on Jul. 18, 2013. A variation of the tensioning device is also described in U.S. Pat. No. 7,198,610, granted on Apr. 3, 2007, and U.S. Pat. No. 9,125,730, granted Sep. 8, 2015, which are incorporated herein by reference and belong to the assignee of this disclosure. Commercial examples of a tensioning device that may also be used with different embodiments of the support include the BOA lacing system of BOA Technology Inc. of Steamboat Springs, Colo.
(61) The tensioning device is not limited to dial tensioning or a winding system but may include other ratcheting type systems such as a ladder ratchet strap, as discussed in U.S. Pat. No. 7,198,610. Alternatively, the tensioning device can be simplified as a clasp arranged to disengage from the cables and lockingly engage upon a desired tension in the cable by applying traction or wedging. Examples of clasp or blocking devices are described in U.S. Pat. No. 5,566,474, granted Oct. 22, 1996, U.S. Pat. No. 7,082,652, granted Aug. 1, 2006, U.S. Pat. No. 7,360,282, granted Apr. 22, 2008, each of which are incorporated by reference. From the foregoing, a variety of tensioning devices may be employed in combination with the cable that enable locking of a desired tension in the cable and the selective release of tension of the cable.
(62)
(63) In observing
(64) In an alternative, the support may be arranged so that openings do not overlap. While in this alternative the support may not shorten or lengthen according to an increase in tension in the cable, the support can still adapt to a surface along which it is located. A variation of such alternative may include different cables extending along across the openings rather than a cable extending about the guide 171. The cable ends may be anchored at the head portion 172 or other suitable location, and each cable may be adjusted differently so as to create different shape profiles of the first and second peripheries 161, 162.
(65) One of the features the support may have is the overlapping shape described with
(66)
(67)
(68)
(69)
(70)
(71) The support 194 may likewise have different patterns of openings according to the sections, or may have yet further varying openings within a section itself. The first section 174 is shown with elongate openings 195 generally uniformly spaced apart by height H.sub.4, whereas the second section 175 has circular openings 196 spaced apart by height H.sub.5 which may be different from height H.sub.4. Alternatively, the second section 175 may be devoid of openings so that this region is substantially non-adjustable in height. The third section 176 has openings 197 of differing lengths to cross the length adjustment axis 165, and may be spaced apart differently according to where they are located within the third section 176. For example, some openings are spaced apart by height H.sub.6 whereas other openings are spaced apart by height H.sub.7 which is different from height H.sub.6.
(72) According to the embodiments described herein, a cable system and a tensioning device may be adapted to different configurations.
(73)
(74)
(75)
(76) In any of the cable configurations, the tensioning device is not limited to being centrally located along the cable configuration but may be located so the initial lengths of the first and second cable segments are disproportionate relative to one another to achieve different contouring and tensioning of each of the first and second cable segments. By placing the tensioning device generally in the middle of the cable configuration, the support may probably have a generally uniform contraction. Alternatively, by disproportionately placing the tensioning device in the cable configuration, there may be non-uniform contraction so the shape of the support may contort.
(77) The cable configuration is not limited to a single tensioning device, however it is envisioned that multiple cables may be employed that are respectively tensioned independently from one another by their own or shared tensioning devices. Additionally, while the cable configurations schematically show the cable as generally linearly extending through or relative to the body of the support, the cable may be arranged so that it alternates between opposed sides of the length adjustment axis, either terminating at an anchor or returning toward or to the tensioning device much like lacing of shoes.
(78) While the cable is described as extending through the body of the support in certain embodiments, it may be located along at least one of the surfaces of the body with external guides channeling the course of the cable. Alternatively, the support body may define channels within the thickness of the body through which the cable extends. Essentially, the cable configuration is arranged so that adjusting a length of the cable relative to the support enables length adjustment and/or shape contouring of the support, whether the cable is internally or externally mounted relative to the support.
(79) From these cable configurations and the aforementioned embodiments, a method for adjusting a length involves adjusting tension in the at least one cable or cable segments by regulating the tensioning device and causing geometry of the at least one opening to modify according to tension in the cable. Ends of the support are preferably anchored at first and second locations such that the length of the support adjusts along the length adjustment axis according to regulation of the tensioning device. By providing at least one peripheral opening along a periphery of the support, the shape of the support may be contoured according to regulation of the tensioning device by modifying a geometry of the peripheral opening as a result in adjustment of tension in the at least one cable.
(80)
(81) As with the embodiment of
(82) The shape of the main body 302 may vary depending on the tension of the cables 316, 318 such that the opening 329 may be elongate, whereas reducing the tension will cause the opening 329 to reflect a more circular profile. As with the embodiment of
(83)
(84) In this embodiment, a rear surface of the elongate body 82 may include silicone to assist in maintaining the support 80 in position over the knee. The strap is particularly used to exert a downward force on the patella and a lateral to medial pull. As with any of the embodiments, the connection assembly 88 may be secured to the elongate body 82 by stitching 44 extending through a plurality of apertures 46 formed by the connection assembly 88.
(85)
(86)
(87)
(88)
(89) The first and second extensions 218, 219 include connection elements 220 for securing to the orthopedic device 270 at frame supports 276, 278 spaced apart by struts 280, 282. The second side portion 217 includes bifurcated first and second extensions 221, 222. The first and second extensions 221, 222 of the second side 217 include connection elements 223, and may extend over or underneath the strap assembly 272, 274 supported by the unloading device 270.
(90) Referring to
(91) The support may be constructed of a material that is substantially rigid or becomes sufficiently rigid to place and maintain an ankle in a desired eversion or inversion configuration according adjustment by the tensioning device. The support may be sufficiently compressible to enable comfort to the user's ankle as the support is adjusted. The shape or geometry of the support may be adapted for contouring to a user's ankle such in the illustrated example whereby the width of the support tapers from the foot plate to the upper portion.
(92) The embodiments of the support described above in accordance with the present disclosure reduce pain, speed healing processes, and impart improved stability and mobility in numerous indications. In an orthopedic device, for example, the support permits more precise adjustment and enables efficient coordination between a medical professional and the wearer on the degree the orthopedic device should be configured. Patient comfort is also enhanced and donning and doffing of the orthopedic device is eased with the novel features described.
(93) It is to be understood that not necessarily all such objects or advantages may be achieved under any embodiment of the disclosure. Those skilled in the art will recognize that the support, either by itself or combined with another article such as an orthopedic device, may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught without achieving other objects or advantages as taught or suggested.
(94) The skilled artisan will recognize the interchangeability of various features from different embodiments. Besides the variations described, other known equivalents for each feature can be mixed and matched by one of ordinary skill in this art to construct a support or an orthopedic device under principles of the present disclosure.
(95) Although the support has been disclosed in certain preferred embodiments and examples, it therefore will be understood by those skilled in the art that the present invention extends beyond the specifically disclosed embodiments to other alternative embodiments and/or uses of the support and obvious modifications and equivalents thereof. It is intended that the present disclosure should not be limited by the particular disclosed embodiments described above.
