Abstract:
1. A suspension liner sleeve adapted to provide an interface between a residual limb and a prosthetic socket, comprising: an elongate, generally conical body portion having an axis and formed of a material that is at least radially extendible from a relaxed non-extended condition and defining an open proximal end and a closed distal end, an outermost layer of the body portion being formed from a textile cover; at least one resilient seal element formed from an elastomeric material and defining proximal and distal portions extending along the outermost layer and a middle section extending between the proximal and distal portions, the at least one seal element extending outwardly relative to the axis from the distal portion toward the proximal portion such that a thickness of the at least one seal element at the proximal portion is greater than a thickness of the at least one seal element at the distal portion, the proximal portion having a section extending substantially perpendicular relative to the axis; wherein the at least one seal element annularly extends around the body portion at the distal end thereof.
