An ankle prosthesis or orthosis includes a tibia portion, at least one foot clamping member, at least one upper foot part, at least one lower foot part, at least a first piston, at least a second piston, which allows that internal rotational movement, inversion and eversion of the ankle joints and alignment thereof with a below-knee mechanism at 0 degrees are performed in an efficient manner is disclosed.

TRACTION SYSTEM FOR AN AMBULATORY SUPPORT

A traction system for an ambulatory support such as a prosthetic foot blade or a crutch includes a sole plate, a latch assembly, and a strap. The sole plate is couplable to a distal end of the ambulatory support to extend under a bottom side of the ambulatory support and a latch assembly. The latch assembly includes a front catch and a rear catch both fixable at a top side of the ambulatory support with the front catch nearer to the distal end of the ambulatory support than the rear catch, and a lever having a front end and a rear end, the front end releasably latchable to the front catch and the rear end releasably latchable to the rear catch when the lever is pivoted about the latched front end. The strap is secured to the lever and to the sole plate.

Post-operative residual limb support assembly
10729565 · 2020-08-04 · ·

An upper extremity post-operative residual limb support assembly includes an upper frame; a lower frame adjustably coupled to the upper frame; a liner coupled to the upper frame and the lower frame, the liner including: a first liner portion configured to be positioned adjacent the upper frame and extend at least partially about an arm of a user; and a second liner portion configured to be positioned adjacent the lower frame, the second liner portion including a closed end configured to receive a distal end of a residual portion of the arm.

Prosthetic limb and prosthetic limb attachment for swimming

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.

Above the knee post-operative residual limb support
10639172 · 2020-05-05 · ·

An above-the-knee post-operative residual limb support device is described. The support device may be used shortly after amputation of a portion of a limb, such as a portion of a patient's leg (e.g., such as in an above-the knee (AK) amputation procedure). Such a support device may be referred to as an Immediate Post-Operative Prosthesis (IPOP).

Non-snag prosthetic foot and leg
10568750 · 2020-02-25 · ·

The present disclosure illustrates a prosthetic foot that may reduce snagging on external obstacles. In some embodiments, a prosthetic foot includes a symmetric wear member that is rotatable to allow a user to alter an orientation of the symmetric wear member for even wear. A cuff may couple to the symmetric wear member, and include the proximal end comprising a receptacle with an opening having an adjustable diameter. The receptacle may be sized and shaped to receive and selectively retain the prosthesis pylon by adjusting the diameter of the opening. The prosthetic foot may further include a vertical adjustment mechanism that selectively alters a depth of the receptacle of the cuff to vertically displace the prosthesis pylon.

Synergetic Prosthesis
20190209347 · 2019-07-11 ·

The synergetic prosthetic system comprises of a knee and an ankle sleeve on the functional leg and a prosthesis on the amputated leg. Each sleeve comprises of a power supply, an accelerometer, a wireless transmitter and a wire connecting the accelerometer to the wireless transmitter. The prosthesis comprises of a power supply, a microcontroller, servo motors, a knee joint assembly, and an ankle joint assembly. A steel rod covered with a casing connects the knee and ankle joints. The accelerometer measures and transmits the angle of rotation of the functional knee and ankle joint to a microcontroller. The microcontroller pre-programmed with normal gait data pairs the data from the healthy leg and controls the servo motors. The servo motors, move the prosthetic joints to mimic a normal human gait.
