Abstract
A prosthetic liner includes a flexible elongate, generally conical body portion formed from an elastomeric material. The body portion defines an inner surface, an outer surface forming a liner profile between a distal end and a proximal end, and an axis extending between the distal and proximal ends. At least one seal element extends circumferentially about the axis and protrudes radially outward a distance from the liner profile. The at least one seal element has a seal height defined between the liner profile and a radially outward end of the at least one seal element. The seal height varies circumferentially about the axis between a first seal height and a second seal height.
Claims19
A prosthetic liner adapted to provide an interface between a residual limb and a prosthetic socket, the prosthetic liner comprising:
- a body portion having an elongate and generally conical shape and formed from an elastomeric material, the body portion defining an inner surface, an outer surface forming a liner profile between a closed distal end and an open proximal end, and an axis extending between the distal end and the proximal end;
- wherein the body portion includes a seal element region having at least one seal element formed by the prosthetic liner and the elastomeric material of the body portion, said at least one seal element variably protruding radially outward relative to the axis about a circumference of the body portion such that the at least one seal element at least defines a first seal height and a second seal height at first and second circumferential positions, respectively, about the circumference of the body portion;
- wherein the first and second seal heights are defined by a distance between the outer surface of the liner profile adjacent to the first and second seal heights and a radially outward end of the at least one seal element measured normal to the liner profile, the first seal height being different from the second seal height.

- wherein the at least one seal element defines first and second plane side areas protruding radially from the liner profile and distally toward each other to a radially outward end;
- wherein the first and second seal heights are defined by a distance between the outer surface of the liner profile adjacent to the first and second seal heights and a radially outward end of the at least one seal element measured normal to the liner profile, the first seal height being different from the second seal height.
