Suspension liner system with seal

A suspension liner sleeve adapted to provide an interface between a residual limb and a prosthetic socket, the liner sleeve comprising:

• an elongate, generally conical liner body portion having a first section with a generally uniform thickness;
• and
• at least one resilient seal element formed from an elastomeric polymeric material and protruding radially and annularly from the liner body portion, the at least one seal element defining:
• a peak defined as an outermost extending portion of the at least one seal element,
• a distal curvilinear section extending from the peak to a distal root adjacent and attached to the liner body portion,
• a proximal curvilinear section extending from the peak to a proximal root adjacent and attached to the liner body portion, and
• at least one annular recess formed from a layer of the elastomeric polymeric material and located adjacent to one of the distal and proximal curvilinear sections;
• wherein the liner body portion includes a first layer formed from a first polymeric material and is located along and defines an inner peripheral surface of the suspension liner sleeve;
• wherein a thickness of the suspension liner sleeve at the at least one seal element from the inner peripheral surface to the peak of the at least one seal element comprises the first layer forming the inner peripheral surface, the at least one seal element forming an outer peripheral surface of the suspension liner sleeve, and a textile material segment interposed between the first layer and the at least one seal element;
• wherein the at least one resilient seal element includes first and second seal elements, the liner body portion defining a clearance between the first and second seal elements, the liner sleeve having a generally uniform thickness across the clearance;
• wherein the clearance spans a distance between a first annular recess corresponding to the first seal element and a second annular recess corresponding to the second seal element.
