ABSTRACT:
Apparatus for effecting comfortable fitting of a prosthetic appliance over an amputee's limb stump which has an irregular surface. The apparatus includes a liner surrounding the stump. The liner is, in turn, at least indirectly, connected to the artificial limb. A vacuum pump is provided, the pump serving to draw vacuum at an interface of the stump and an inner wall of the liner, and a plurality of pressure-sensitive transducers are disposed about the stump at locations spaced from each other. The apparatus includes a controller, responsive to pressure reduction sensed by the transducers, to actuate the vacuum pump
