Abstract:
1. A suspension liner adapted to provide an interface between a residual limb and a prosthetic socket, the suspension liner defining an interior surface and an exterior surface forming a liner profile between a closed distal end and an open proximal end, the suspension liner comprising: a flexible elongate, generally conical liner body portion formed from an elastomeric material; a reinforcement material embedded into a thickness of the elastomeric material of the liner body portion, the reinforcement material being generally axially stiff and radially compliant, the reinforcement material being different from the elastomeric material; at least one seal protruding circumferentially about and radially outwardly a distance from the liner profile, which liner profile is defined at areas outside the at least one seal, the at least one seal formed in one piece with the elastomeric material of the liner body portion, the at least one seal having a radially bendable peak at least in part defining a sealing surface arranged to deflect toward the liner profile and take up a higher pressure when donned on a residual limb and engaged with an interior wall of a prosthetic socket, wherein the sealing surface is arranged such that a form of the at least one seal increases sealing forces with the higher pressure existing at the radially bendable peak and along an upper portion of the at least one seal as compared to a distal portion of the at least one seal.
