An assembly for effecting comfortable fitting of a prosthetic appliance over an amputee's limb stump which has an irregular surface. The assembly includes an inner, stump surrounding liner which is at least indirectly connected to an artificial limb, an outer, prosthesis socket receiving liner, and a vacuum pump for evacuating the interstitial spaces between the stump and the assembly and the prosthesis and the assembly. A plurality of pressure-sensitive transducers are further provided and disposed about the stump at locations spaced from each other, in addition to a controller, responsive to pressure reduction sensed by the transducers, to activate the vacuum pump to thereby form fit and adjust the assembly relative to the stump and the prosthesis relative to the assembly as the situation warrants.
