Patent ID: 7850740

Claim:
A prosthesis system comprising: a prosthetic limb having a prosthetic socket, the prosthetic socket including a proximal end, a distal end, a rigid structure disposed at the distal end, and a sleeve extending from the distal end towards the proximal end and forming an opening at the proximal end to receive a residual limb, the rigid structure having a portion extending from the distal end toward the proximal end; a sub-dermal strut configured for placement under the skin of the residual limb, the sub-dermal strut having a distal end and a proximal end and a flange extending from the distal end of the sub-dermal strut toward the proximal end of the sub-dermal strut; an anchoring post attached to the sub-dermal strut and configured to anchor to a bone of the residual limb; at least two discrete magnets, one of the discrete magnets being disposed on the flange and the other discrete magnet being disposed at the distal end of the sub-dermal strut; a magnet set including at least two set magnets disposed on the portion of the rigid structure, the at least two magnets being arranged and configured to generate magnetic fields extending inwardly toward a longitudinal center axis of the sleeve; and an individual magnet disposed on the rigid structure.
