DETAILED DESCRIPTION

[0048] With reference to FIG. 1, there is shown a multifunctional brace 10 in accordance with an embodiment of the present invention, generally indicated by the reference numeral 10. The brace 10 is intended to be used for aligning and protecting a patella 12 (schematically illustrated in phantom lines) part of a knee 14 of a leg of an intended user. The knee 14 allows bending of the leg between an upper leg segment 16 and a lower leg segment 18. As is well known, the patella 12 is attached to a patellar tendon 20 (also shown in phantom lines).

[0049] Although the brace 10 is described as a knee brace, it should be understood that the brace 10 could be used with slight modifications on different body parts such as elbows, ankles, wrists or any other suitable body part without departing from the scope of the present invention.

[0050] The brace 10 includes a mounting component 22 for mounting the brace 10 to the leg of the user. The mounting component 22 typically takes the form of a tubular sleeve 24 made of a substantially elastomeric material. For example, the mounting component could be made of Neoprene© or any other suitable material. In such instances, the sleeve 24 is configured and sized so as to be slidable over the knee 14 and to be frictionally retained in proper alignment with the knee 14 without causing discomfort to the user.

[0051] Also, the mounting component 22 could include two or more mounting component segments (not shown) attached to the upper leg segment 16 and lower leg segment 18. In such instances, the mounting component segments could be made of more rigid material and attached together by a hinge.

[0052] The brace 10 also includes a first attachment component 26 attached to the mounting component 22. The brace 10 further includes a second attachment component 28. The second attachment component 28 is typically in a substantially superposed relationship relative to the first attachment component 26.

[0053] Typically, the brace 10 also has an alignment component 30 for aligning the patella 12 in a proper position within the femoral notch formed by the condyles at the distal end of the femur. The alignment component 30 is attached to the mounting component 22 by the first attachment component 26.

[0054] Typically, the brace 10 further includes a cushioning component 32 for cushioning the patella against impact threreon. The cushioning component 32 is attached to the mounting component 22 by the second attachment component 28.

[0055] Preferably, the cushioning component 32 is releasably attached to the mounting component 22 by the second attachment component 28. Also preferably, the alignment component 30 is releasably attached to the mounting component 22 by the first attachment component 26.

[0056] Typically, the brace 10 further includes a therapeutic component 34 for promoting the health of the knee 14. The therapeutic component 34 is releasably attachable to the mounting component 22 by the first attachment component 26. In use, the alignment component 30 and the therapeutic component 34 are adapted to be alternatively attached to the mounting component 22 by the first attachment component 26.

[0057] In one embodiment of the invention, the therapeutic component 34 takes the form of a therapeutic pad 36. The therapeutic pad 36 can be a cryotherapy pad used for icing anatomical structures around the patella such as tendons and ligaments. In such instance the therapeutic pad 36 is provided with an icing pad aperture 38 extending therethrough.

[0058] The icing pad aperture 38 defines an icing pad aperture peripheral edge configured and sized for substantially surrounding the patella 12. The icing pad aperture 38 hence allows the icing pad 36 to cool around the patella 12 without directly icing over the patella 12.

[0059] The therapeutic pad 36 could also be used as a thermal therapy pad for delivering heat to the anatomical structures around the patella 12. The therapeutic pad 36 could further be used for delivering analgesic or therapeutic substances or for any other suitable therapeutic action without departing from the scope of the present invention.

[0060] In one embodiment of the invention, the first attachment component 26 includes a first attachment pocket extending from the sleeve 24 for receiving the alignment component 30 or the therapeutic component 34. The first attachment pocket is positioned so as to be positioned substantially over the knee 14 when the sleeve 24 is worn by the user.

[0061] The first attachment pocket typically includes a first pocket inner wall 40 and a first pocket outer wall 42. The first pocket inner wall 40 and first pocket outer wall 42 are attached together along their respective side and bottom edges so as to define a pair of closed first pocket side edges 44 and a closed first pocket bottom edge 46. The first attachment pocket defines a first pocket mouth 48 for slidably receiving the alignment component 30 or the therapeutic component 34.

[0062] The first pocket mouth 48 can be closed by joining the top edges of the first pocket inner wall 40 and the first pocket outer wall 42. for selectively preventing withdrawal of components inserted in the first attachment pocket. The first pocket mouth 48 is typically provided with a first mouth releasable locking means for releasably locking the first pocket mouth in a closed position.

[0063] In one embodiment of the invention, the first mouth releasable locking means includes cooperating strips 50 of Velcro© extending along the inner surface of the first pocket inner wall 40 and the first pocket outer wall 42 adjacent their respective top edges. The first mouth releasable locking means can take the form of a zipper-type mechanism, a locking flap or any other suitable means without departing from the scope of the present invention.

[0064] When the first attachment component 26 takes the form of a first attachment pocket, the peripheral edges of the first pocket inner wall 40 are attached to the mounting component 22 using a pocket-to-mounting component attachment means designated by the reference numeral 52. The pocket-to-mounting component attachment means 52 may take the form of stitches, thermal welding lines or any other suitable means without departing from the scope of the present invention.

[0065] The tubular sleeve 24 is typically provided with a sleeve window 54 extending therethrough. The sleeve window 54 is typically substantially in register with at least a portion of the first pocket inner wall 40 for allowing the at least a portion of the first pocket inner wall 40 to be in contact with the knee 14 of the intended user. The sleeve window 54 also allows at least a portion of the alignment component 30 to be in a more proximal relationship with the knee 14 of the intended user then it would be without the sleeve window 54.

[0066] In one embodiment of the invention, the second attachment component 28 includes a second attachment pocket for receiving the cushioning component 32. The second attachment pocket is positioned so as to be in a substantially overlapping relationship relative to the first attachment pocket.

[0067] The second attachment pocket typically includes a second pocket inner wall 56 and a second pocket outer wall 58. The second pocket inner wall 56 and second pocket outer wall 58 are attached together along their respective side and bottom edges so as to define a pair of closed second pocket side edges 60 and a closed second pocket bottom edge 62. The second attachment pocket defines a second pocket mouth 64 for slidably receiving the cushioning component 32.

[0068] The second pocket mouth 64 can be closed by approaching the top edge of the second pocket inner wall 56 and the second pocket outer wall 58 for selectively preventing withdrawal of components inserted in the second attachment pocket. The second pocket mouth 64 is typically provided with a second mouth releasable locking means for releasably locking the second pocket mouth in a closed position.

[0069] In one embodiment of the invention, the second mouth releasable locking means includes cooperating strips 50 of Velcro© extending along the inner surface of the second pocket inner wall 56 and the second pocket outer wall 58 adjacent their respective top edges. The second mouth releasable locking means can take the form of a zipper-type mechanism, a locking flap or any other suitable means without departing from the scope of the present invention.

[0070] When the second attachment component 28 takes the form of a second attachment pocket, the peripheral edges of the second pocket inner wall 56 are attached to the mounting component 22 using a pocket-to-mounting component attachment means designated by the reference numeral 52. The pocket-to-mounting component attachment means 52 may take the form of stitches, thermal welding lines or any other suitable means without departing from the scope of the present invention.

[0071] The alignment component 30 typically includes an alignment pad 66. The alignment pad 66 is typically provided with an alignment aperture 68. The alignment aperture 68 defines an alignment aperture inner edge. The alignment aperture inner edge is configured and sized for substantially surrounding at least a portion of the patella 12 of the intended user.

[0072] In a preferred embodiment of the invention, the alignment aperture inner edge has a substantially circular main edge segment 70 and an auxiliary edge segment 72. The auxiliary edge segment 72 is configured, sized and positioned for surrounding at least a portion of the patellar tendon 20 when the sleeve 24 is properly positioned over the knee 14.

[0073] Typically, the alignment pad 66 defines an alignment pad inner surface 74 and an alignment pad outer surface 76. As shown more specifically in FIG. 3, the alignment pad 66 is provided with an abutment component 78 extending from the alignment pad inner surface 76 adjacent the main edge segment 70.

[0074] The abutment component 78 is shown having the configuration of an interrupted and truncated torus, the torus being circumferentially truncated in half and interrupted about the auxiliary edge segment 72. It should however be understood that the abutment component 78 could have any other suitable shape without departing from the scope of the present invention.

[0075] In a preferred embodiment of the invention, the cushioning component 32 is a cushioning pad 80. The cushioning pad 80 is made of an impact absorbing material.

[0076] The first and second pockets, the therapeutic pad 36, the alignment pad 66 and the abutment component 78 are all shown throughout the drawings has having a substantially parallelepiped-shaped configuration. It should however be understood that these component could have any other suitable configuration without departing from the scope of the present invention.

[0077] In an alternative embodiment of the invention, illustrated more specifically in FIG. 4, there is shown a brace 10′ further including a medializing component 82 for progressively medializing the position of the patella 12 of the intended user.

[0078] Since the brace 10′ is otherwise similar to the previously described brace 10, similar reference numeral will be used to designate similar components and only the sleeve 24 and associated medializing component 82 will be shown. It should however be understood that the brace 10′ includes the other components of brace 10.

[0079] The medializing component 82 includes a medializing tongue 84 extending from the mounting component 22. The medializing tongue 84 has a medializing aperture extending therethrough. The medializing aperture defines a medializing edge 86 for abutting against a lateral portion of the patella 12.

[0080] The medializing component 82 is provided with an adjustment means for allowing the intended user to adjust the position of the medializing edge relative to the mounting component 22. The adjustment means preferably acts also acts as a biasing means for biasing the patella towards proper alignment.

[0081] In the embodiment illustrated in FIG. 4, the medializing component 82 includes a medializing component attachment section 88 for attachment to the mounting component 22. At least a portion of the medializing component attachment section 88 is made of reversibly deformable or elastic material.

[0082] The medializing component 82 also includes a medializing component locking segment 90 extending from the medializing tongue substantially opposite the medializing component attachment section 88 for releasably locking the medializing edge 86 in a predetermined relationship relative to the mounting component 22

[0083] A terminal portion 94 of the medializing component locking segment 90 extends underneath the inner surface of the sleeve 24 through a tongue aperture 92 formed in the sleeve 24. A tongue fixing means (not shown) such as a pair of Velcro© strips, a clip or any other suitable means is used for releasably locking the terminal portion 94 to the exterior surface of the sleeve 24.

[0084] A marking system may be used for providing a visual clue to the intended user about the progression of the medialization an allowing for more precise adjustment of the position of the of the medializing edge 86.

[0085] In the illustrated embodiment, the marking system includes a tongue line 96 marked on the terminal portion 94 and lines 98 on an adjacent section of sleeve 24. It should however be understood that any other suitable marking means could be used without departing from the scope of the present invention.

[0086] In use, the user pulls on the medializing component locking segment 90 stretching the elastic portion of the medializing component attachment section 88 and allowing lateral displacement of the medializing edge 86. The elastic portion of the medializing component attachment section 88 is prevented for springing back to its original configuration by the tongue fixing means.

[0087] At given intervals of time, when judged appropriate, the tongue fixing means is temporarily released so as to allow the elastic portion of the medializing component attachment section 88 to gradually spring back, by increments, towards its original configuration, hence allowing the medializing edge 86 to gradually medialize the patella 12.

[0088] In yet another embodiment of the invention, there is provided a brace 10″ substantially similar to brace 10 except that brace 10″ is intended to be used with an existing cushioning component and an existing aligning or therapeutic component. The existing cushioning component and existing aligning or therapeutic component could be similar to the ones herein disclosed or display different characteristics without departing from the scope of the present invention. Since brace 10″ is substantially similar to brace 10, the same drawings are used to illustrated brace 10 and 10″, brace 10″ being referred to as brace 10 throughout the drawings.

[0089] Similarly to brace 10, brace 10″ includes a mounting component 22 for mounting brace 10″ to a chosen body part of an intended user such as a leg or other suitable body part. Similarly to brace 10, brace 10″ includes a first attachment component 26 attached to the mounting component 22 for attaching the existing alignment component 30 to the mounting component 22 so that at least a portion of the alignment component 30 is positioned substantially over the chosen body part 14 when the mounting component 22 is mounted on the chosen body part of the intended user.

[0090] Similarly to brace 10, brace 10″ also includes a second attachment component 28 for attaching the existing cushioning component 32 to the mounting component 22. The second attachment component 28 is typically in a substantially superposed relationship relative to the first attachment component 26 so that the alignment component 30 is positioned between the chosen body part and the cushioning component 32 when the mounting component 22 is mounted on the chosen body part of the intended user.

[0091] Typically, the first attachment component 26 allows for releasable attachment of the alignment component 30 to the mounting component 22 and the second attachment component 28 allows for releasable attachment of the cushioning component 32 to the mounting component 22.

[0092] Similarly to brace 10, brace 10″ may include a therapeutic component 34 for promoting the health of the knee. The therapeutic component 34 is typically releasably attachable to the mounting component 22 by the first attachment component 26. Brace 10″ can be used either with any combination of alignment component 30, cushioning component 32 or therapeutic component 34 without departing from the scope of the present invention.

[0093] When used with both an alignment component 30 and a therapeutic component 34, the alignment component 30 and the therapeutic component 34 are adapted to be alternatively attached to the mounting component 22 by the first attachment component 26.
