Suspension liner system with seal

A suspension liner adapted to provide an interface between a residual limb and a prosthetic socket, and defines an interior surface and an exterior surface forming a liner profile with a closed distal end, the suspension liner comprising:

• an elongate, generally conical liner body portion formed from at least one type of polymeric material;
• at least one textile segment secured to and substantially coextensive with the liner body portion;
• first and second seals protruding circumferentially about and radially outwardly from the liner profile and separated by a clearance along the liner profile;
• wherein the first and second seals are defined by a molded portion of the at least one type of polymeric material forming the liner body portion continuously extending through the at least one textile segment and are unitary and integrally formed with the liner body portion, the first and second seals each form an outward radial extremity of the exterior surface of the suspension liner beyond the clearance formed between the first and second seals, the first and second seals are arranged for deflection toward the liner profile when donned on a residual and placed within a prosthetic socket;
• wherein the at least one type of polymeric material continuously extends through the at least one textile segment and is formed on opposed sides of the at least one textile segment at least at a location corresponding to the first and second seals.

A suspension liner adapted to provide an interface between a residual limb and a prosthetic socket, and defines an interior surface and an exterior surface forming a liner profile with a closed distal end, the suspension liner comprising:

• an elongate, generally conical liner body portion formed from at least one type of elastomeric silicone, liner body portion defining the interior surface of the suspension liner;
• at least one textile segment secured to and substantially coextensive with the liner body portion;
• a distal reinforcing cup provided at the closed distal end of the suspension liner;
• first and second seals protruding circumferentially about and radially outwardly from the liner profile and separated by a clearance along the liner body portion;
• wherein the first and second seals are defined by a molded portion of the elastomeric silicone forming the liner body portion continuously extending through the at least one textile segment and are unitary and integrally formed with the liner body portion, the first and second seals each form an outward radial extremity of the exterior surface of the suspension liner beyond the clearance formed between the first and second seals, the first and second seals are arranged for deflection toward the liner profile when donned on a residual and placed within a prosthetic socket;
• wherein the elastomeric silicone continuously extends through the at least one textile segment and is formed on opposed sides of the at least one textile segment at least at a location corresponding to the first and second seals.
