  • Patent number: 10966845
    Abstract: A prosthetic liner for use with a prosthetic assembly that acts as the interface between the residual limb of an amputee and the socket assembly. The prosthetic liner comprises an outer textile with variable stretch characteristics due to the knit construction and stitching and an interior gel layer. The distal region of the liner textile has less stretch than does the intermediate region or proximal region and is stitched together to form a unitary liner. The liner advantageously minimizes a condition referred to as “pistoning” wherein the distal most portion of the residual limb ascends and descends in the lower portion of the socket creating an unhealthy condition for the residual limb.

  • Patent number: 10945868
    Abstract: Thin-film mesh for medical devices and related methods are provided. The thin-film mesh may include slits to be expanded into pores, and the expanded thin-film mesh may be used as a cover for a stent device. The thin-film mesh has a tube-shape and the slits may be angled with respect to a longitudinal axis of the tube-shape thin-film mesh. The angled slits allow for the thin-film mesh to expand in multiple dimensions, including along the longitudinal axis and along the circumferential direction of the tube-shape thin-film mesh. The slits may be provided in diagonal rows arranged in longitudinal columns. Longitudinal columns of different types of slits may be arranged along the circumferential direction on the tube-shape thin-film mesh to form a zig-zag pattern of slits.

  • Patent number: 10864091
    Abstract: A prosthetic knee having a passive knee locking mechanism that uses the same four-bar mechanics found in a natural knee. The flexible four-bar mechanism guides the motion of the knee, aids in the return of the knee from full flexion to extension, and connects a femoral gear to a tibial gear. The gears have a circular radius and are connected using parallel links to keep the femur and tibia together when the knee is active. The knee stays locked throughout the stance phase. At toe off, no weight is applied on the prosthetic knee allowing the knee to flex. The flexible links are stretched, thereby increasing the stiffness in the springs, and at terminal swing phase, moments before heel strike, the flexible links in the four-bar mechanism snap back to the extended/locking position and lockout once the user applies his/her weight on the knee.
