Abstract:
1. An interface for filling gaps that form between a limb liner and a socket of a prosthetic limb, said interface comprising: a double-layered body having a bottom end and an open top end, wherein a mounting pin hole is disposed through said bottom end; said body having an interior layer and an exterior layer wherein said interior layer is connected to said exterior layer in a first predetermined area surrounding the mounting pin hole, said first predetermined area being a concentric circle surrounding said hole where the interior layer lays flush against said exterior layer, and wherein said interior layer is connected to said exterior layer in a second predetermined area proximate said open top end; a gap space separating said interior layer and said exterior layer within said body at all points between the first predetermined area and second predetermined area, so that the first predetermined area and second predetermined area are of a lesser thickness than the body at all points between the first predetermined area and second predetermined area, wherein both said interior layer and said exterior layer are made of air-impervious material; and a vent for selectively controlling air flow into and out of said gap space.
