ABSTRACT:
An inflatable lower limb prosthesis comprises an outer cover of relatively inextensible material defining the shape of a leg prosthesis and having a pad of rigid material at its lower end defining the shape of a foot. An inner member of independently inflatable compartments welded together comprises a shin compartment contacting the rigid pad and of upwardly convergent profile, an inner spacer compartment between the upper end of the shin compartment and the patient's stump and an annular socket compartment that surrounds the patient's stump and extends downwardly in overlapping relation around the upper end of the shin compartment to resist bending of the prosthesis at the false joint at the patient's stump.
