1. A prosthesis liner system comprising:
a porous prosthesis liner having a perforated distal end, and
a valve for said porous prosthesis liner, the valve comprising:
a first portion comprising:
means for locating the valve on the distal end of the porous prosthesis liner; and
a frusto-conical shaped inner circumferential band having a first thickness; and
a second portion extending from the first portion of the valve to a peripheral edge of the valve, the second portion comprising a frusto-conical shaped outer circumferential band having a second thickness which is not equal to the first thickness, thereby resulting one of the inner and outer circumferential bands being a thinner circumferential band and the other one of the inner and outer circumferential bands being a thicker circumferential band,
wherein the thinner circumferential band is resiliently deformable and movable between:
a first, at rest, position where the thinner circumferential band is adapted to abut a corresponding portion of the distal end of said porous prosthesis liner, and
a second position where the thinner circumferential band is adapted to be spaced from said corresponding portion of the distal end of said porous prosthesis liner,
wherein the means for locating the valve on a distal end of the said porous prosthesis liner comprises means for preventing lateral movement of the valve relative to the distal end of the said porous prosthesis liner.
