1. A method for retrofitting a socket used in a vacuum suspension system, wherein
the vacuum suspension system comprises the socket, a stump liner, and a vacuum pump, with the socket being a rigid container having substantially continuous side and bottom walls and inner and outer surfaces and an open top end defined by a top edge, thereby forming an interior space, said interior space being configured to receive a residual stump of an amputee, said socket further providing an attachment means on its outer surface for securing a prosthetic leg thereto, the stump liner being a flexible sleeve configured to fit snugly over the residual stump, the stump liner being substantially air impermeable, said stump liner being capable of forming an air impermeable barrier against the inner surface of the socket when worn over the residual stump and placed into the socket, and the vacuum pump being in communication with the interior space of the socket and being capable of evacuating air from the interior space of the socket to create at least a partial vacuum therein; said method comprising the steps of: A. obtaining a material having a liquid state and a solid state; B. applying the material to the top edge of the socket while the material is in its liquid state; and C. allowing the material to harden into its solid state. |
