Abstract:

A prosthetic device primarily intended for use by amputees and in particular, leg amputees. The prosthesis includes a relatively rigid, support shell dimensioned to receive a portion of the residual limb and a pad member having a plurality of pouches at least partially filled with fluid. The pad member substantially encircles the leg with its fluid pouches being positioned adjacent one another about and along the leg. Each pouch is supported between the leg and the shell and has inner and outer pouch layers with the fluid being contained between them. Portions of each inner layer fold back on one another to form wrinkles wherein slack is maintained in the inner layer so that it can conform to the user's leg without hammocking or being drawn taut. It can also accommodate and move with the user's leg relative to the support shell without being tensioned or distended.
