US12605262B2 Inflatable Limb Prosthesis, Israel Pilosof
Summary
The USPTO granted patent US12605262B2 to inventors Israel Pilosof and Yehuda Pilosof for an inflatable limb prosthesis. The invention includes a socket with an inner cavity configured for disposal of a limb stump, a mechanism for changing the inner diameter via remote control, and an inflatable lining with 15-60 longitudinal cells designed to diminish blood flow blockage. A pump assembly allows inflation/deflation to a user-set air pressure.
What changed
The USPTO issued patent US12605262B2 to inventors Israel Pilosof and Yehuda Pilosof on April 21, 2026. The patent covers a limb prosthesis with a socket cavity for limb stump disposal, a remote-controlled mechanism for adjusting inner diameter, and an inflatable lining comprising 15-60 adjacent longitudinal inflatable cells arranged to minimize blood flow blockage, connected to a pump assembly for user-controlled inflation.
Prosthetics manufacturers and medical device developers should note this intellectual property grant, as it may be relevant to Freedom-to-Operate analyses for similar adjustable-socket prosthetics. The specific arrangement of longitudinal cells without intervening elements represents a defined technical approach now protected under US patent law.

Abstract
A limb prosthesis including a socket having an inner cavity configured for disposal therein of a limb stump of a user, and a mechanism for changing an inner diameter of the inner cavity by a remote control, where the inner diameter includes a lining disposed within the cavity, having between fifteen and sixty of only longitudinal inflatable cells where each of the cells is situated immediately adjacent to two other of the cells such that no intervening element aside from a shared border is provided between two such immediately adjacent cells, thereby diminishing blood flow blockage in the limb stump, and a pump assembly, for inflating and deflating the inflatable lining to a desired air pressure set by a user or by a controller, the remote control being in data communication with the pump assembly, for instructing the pump assembly to inflate or deflate the lining to the desired air pressure.
