Abstract
A prosthetic liner includes a textile cover having at least first and second regions having different elongation from one another. The first region is in a prestretched configuration in at least one orientation relative to an axis of the prosthetic liner and locked in the prestretched configuration according to a layer of elastomeric material located along a surface of the textile cover.
Claims14
A prosthetic liner having a central, longitudinal axis, comprising:
- a textile cover having at least first and second regions with textile configurations having first and second elongation properties, respectively, different from one another as defined relative to the central, longitudinal axis of the prosthetic liner;
- a layer of cured elastomeric material is located along an inner surface of the textile cover across the first and second regions;
- wherein the first and second regions are adjacent to one another along the central, longitudinal axis such that the second region is located proximally relative to the first region, the first and second regions extending circumferentially about the prosthetic liner;
- wherein the first region is in a prestretched configuration in at least one orientation relative to the central, longitudinal axis of the prosthetic liner, and locked and maintained in the prestretched configuration by the layer of cured elastomeric material,
- wherein the second region is in an unstretched configuration relative to the prestretched configuration first region with the layer of elastomeric material secured thereon;
- wherein the second elongation properties of the second region have greater axial elongation relative to the first elongation properties of the first region;
- wherein the first elongation properties have an elongation gradient in which elongation varies across the first region.
