Apparatuses and methods of fabrication are provided which include a mechanical coolant pump to facilitate pumping a coolant through a coolant loop. The mechanical coolant pump is to couple to an individual and be physically powered by a specified movement of the individual to pump coolant. Coolant pumped by the mechanical coolant pump is circulated by the coolant pump through a device associated with the individual to cool the device.

An artificial knee that includes a first knee component having an extension member, a second knee component having a slot configured and dimensioned to allow the extension member to move therein. A fastener connects the knee components to facilitate rotation of the knee components between an upright and rotated positions. The knee components also include a terminal end that includes a central opening and transverse apertures to receive pylons therein. A biasing member of a flexible rod or tube of an elastomeric material urges the knee components towards the upright position when the knee components are rotated. The biasing member passes through the apertures of the terminal ends of the knee components, as well as through the extension member and the slot. Also, a prosthetic leg along with a kit and method for assembling the prosthetic leg.

A prosthetic socket system comprising a prosthetic socket and a liner, said prosthetic socket having a distal end region, at least one socket wall extending therefrom in proximal direction, and connection means for securing a prosthetic component. The socket wall, when in the applied state, at least partially enclose a stump that is received in the prosthetic socket The liner includes a proximal entry opening and a lateral wall which extends in the distal direction, at least partially surrounds a stump when in the applied state and is arranged between the stump and the prosthetic socket when in the applied state. A coupling device is arranged between the liner and the prosthetic socket in the distal end region, and, on the outer side of the lateral wall of the liner and on the inner side of the socket wall, resistance regions are arranged or formed which interact with one another and which counteract a movement extracting said liner out of the prosthetic socket, in the proximal direction.

The invention relates to a process of designing and manufacturing a tailored 3D printed or standard prosthetic socket for a residual limb with a 3D printed distal end, and a computer device for carrying out the process. The process includes obtaining a digital surface of the residual limb and information about the patient, possibly altering the digital surface of the residual limb, creating a shell of the prosthetic socket comprising the altered digital surface of the residual limb, virtually spatially arranging the prosthetic socket including virtual spatial translational or rotational movements of selected prosthetic parts and the prosthetic socket for optimal load transfer from a residual limb to the prosthesis, wherein the structural design of the prosthetic socket is based on the virtual axial adjustment of the prosthesis.

A method of making a thermoplastic gel 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 open proximal end, a closed distal end, and sidewalls comprising an inner layer of molded thermoplastic gel. The thermoplastic gel is molded over a mandrel that has been sandblasted using #36 grit and, optionally, #320 grit at 100 psi so as to form microcraters and reduce the coefficient of static friction.
