Abstract:
1. 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 at least one resilient 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 sleeve defines a thickness at the peak greater than the thickness at the first section of the liner body portion; 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.
