A prosthetic knee can include a variable-torque magnetorheological (MR) actuator assembly or braking system, a frame and an electronics assembly or system that also serves as a mount for the knee actuator and facilitates in monitoring and controlling the operation of the knee actuator. The prosthetic knee system advantageously provides resistive forces to substantially simulate the position and motion of a natural knee joint during ambulation and/or other locomotory activities performed by the amputee. The prosthetic knee can be enclosed in a waterproof compartment. An outer cover can be configured to fit around the waterproof cover of the prosthetic knee.

A transfemoral prosthetic level socket system for a user's lower limb comprising modular socket components fitted to the individual user's residual limb having a mounting point for an attachment, at least one compliant member attached to at least one stabilizing unit, and at least one second compliant member attached to at least one stabilizing unit wherein the first compliant member and the second compliant member work in cooperation with the stabilizing unit(s) to control bone position and support the limb within the interface.

A prosthetic cover for a prosthetic support element can include a substantially cylindrical hollow body with a first end and a second end and sized to fit around a support element of a prosthesis. A first flexible end seal and a second flexible end seal can each attach with the substantially cylindrical hollow body at the first and second ends, respectively, and connect the hollow body with the support element of the prosthesis by deforming about the support element when the prosthetic cover is installed around the support element.

A lower limb prosthetic device for use when bathing and showering includes a first shell. A rod is coupled to and extends substantially perpendicularly from an upper face of the first shell. A second shell, which has a top that is open, is coupled to and extends from the rod distal from the first shell. The second shell is substantially complementary to and configured to insert a stump of an amputated leg. A plurality of bladders, which is selectively inflatable, is coupled to an inner surface of the second shell. The bladders are configured to be inflated to couple the second shell to the stump. A plurality of first holes and a plurality of second holes are positioned through the first shell and the second shell, respectively. The first holes and the second holes are configured to drain water from the first shell and the second shell, respectively.

The present disclosure provides aqueous propulsion devices for prostheses. An aqueous propulsion device may comprise at least one substantially flat protruding extension member configured to extend from an outer surface of a lower-limb prosthesis. In some aspects, the aqueous propulsion device may be configured to be at least temporarily secured to a lower-limb prosthesis via one or more attachment mechanisms. In some implementations, the aqueous propulsion device may comprise a plurality of protruding extension members. In some embodiments, the aqueous propulsion device may comprise two protruding extension members configured on opposing lateral sides of the aqueous propulsion device. In some aspects, securing the aqueous propulsion device to a lower-limb prosthesis may enable a user to swim or otherwise move through a body of water by exerting a pushing force on the water that propels the user in a desired direction when the user kicks or engages in a similar movement.

A prosthesis including a socket configured to receive a residual limb, a pylon attached to the socket, the pylon comprising at least one fin, and an artificial foot attached to an end portion of the pylon.

The invention relates to an automated hand, such as a prosthetic hand. In one form, the automated hand may be fluid compatible. In one form, the automated hand may comprise features to reduce the risk of harm to motors and/or other sensitive components of the hand when subject to an impact. In one form, the hand may comprise a wrist joint configured to allow the hand to curl and flex and/or to rotate. In one form, one or more digits of the hand may be individually controlled. In one form the hand may include a thumb rotation locking mechanism. In one form the hand may be provided with removable grip plates. In one form, the hand may be configured for use as a training hand.

A prosthetic hand with a waterproof cover and/or a filament-based digit securement mechanism. A first annular recess on the digit aligns with a second corresponding annular recess on a chassis to form a groove into which the filament is inserted. The prosthetic hand may comprise a waterproof cover that protects the interior components of the prosthetic hand. A thumb cover and a dorsal cover attach to a palm cover. A thumb cover interface is adhered via a clamp with an exterior sealing ring. A dorsal cover interface has a sealing ring. The thumb cover may be flexible and have three layers. The dorsal cover may be rigid and have a latch that snaps onto the chassis. The cover may be put onto the palm portion with the thumb and thumb cover, and then the prosthetic digits may be attached to the chassis thereafter.
