Inflatable limb prosthesis

A limb prosthesis, comprising:

• a socket comprising an inner cavity configured for disposal therein of a limb stump of a user;
• a means for changing an inner diameter of said inner cavity by a remote control, wherein said means for changing said inner diameter comprises:
• a lining (16) disposed within said cavity, said lining comprising between fifteen and sixty of only longitudinal inflatable cells, each cell comprising an inwardly-facing surface having a convex curvature, wherein each of said cells is situated immediately adjacent to two other of said cells such that no intervening element aside from a shared border is provided between two such immediately adjacent cells
• wherein all of said inflatable cells are configured to inflate simultaneously towards a limb stump disposed in said prosthesis, wherein inflation or deflation of said inflatable cells changes said inner diameter of said cavity, providing an adjustable space between said cells and said limb stump, thereby diminishing blood flow blockage in the limb stump, and wherein upon inflation of said inflatable cells, a gap is generated between said inwardly-facing surfaces having convex curvature of adjacent said cells;
• and
• a pump assembly (19), for inflating and deflating air in the inflatable lining (16) to a desired air pressure set by a user or by a controller,
• wherein said remote control (17) being in data communication with said pump assembly (19), for instructing said pump assembly to inflate or deflate said lining (16) to said desired air pressure.
