Patent ID: 8034120

Claim:
A suspension liner sleeve adapted to provide an interface between a residual limb and a prosthetic socket, the liner sleeve having an inner peripheral surface and an outermost peripheral surface, the liner sleeve comprising: an elongate, generally conical liner body portion formed from at least first and second textile material segments that are at least radially elastically extensible from a relaxed non-extended condition; and a plurality of resilient seal elements protruding radially and annularly from the liner body portion, and defining at least a portion of and being exposed at the outermost peripheral surface of the liner sleeve; wherein at least one seal element of the plurality of seal elements defines a peak defined as an outermost extending portion of the at least one seal element, a distal curvilinear section extending from the peak to the liner body portion, and a proximal curvilinear section extending from the peak to the liner body portion; and at least one annular recess formed from the layer of elastomeric polymeric material; wherein a clearance is formed from the elastomeric polymeric material and defined between each of respective first and second seal elements of the plurality of seal elements; wherein the clearance has a generally uniform first thickness of the elastomeric polymeric material, the at least one annular recess is directly adjacent to the first seal element and the clearance, and the clearance spans a distance between each set of adjacent at least one annular recess and seal element; wherein the plurality of seal elements defines proximal and distal annular borders; wherein areas of the outermost peripheral surface of the liner sleeve adjacent first and second annular peripheries of the plurality of seal elements are defined by the first and second textile material segments; wherein the first and second textile material segments are independent from and formed from a material different from a first elastomeric polymeric material forming the plurality of seal elements.
