Patent ID: 8676341

Claim:
A suture anchor for securing a therapy delivery element to a desired location within a living body, the suture anchor comprising: a deformable anchor body comprising a primary lumen sized to receive the therapy delivery element and at least one exterior suture groove adapted to receive a suture material; an inner sleeve located in the primary lumen, the inner sleeve comprising an inner sleeve lumen aligned with the primary lumen, the inner sleeve comprising an inner layer of a compliant material having a first durometer, and an outer layer of a second durometer greater than the first durometer; at least one compression member disposed over the inner sleeve and recessed within the at least one suture groove, the at least one compression member including a first portion including spaced-apart first ends and a second portion including spaced-apart second ends, the first and second portions together forming a substantially annular shape, wherein the first ends of the first portion are separated by gaps from the second ends of the second portion with the compression member in an open configuration, and wherein the first ends of the first portion abut the second ends of the second portion with the compression member in a compressed configuration, wherein tensioning of the suture material imparts a radial compressive force on the at least one compression member to move the compression member from the open configuration to the compressed configuration; and a reinforcing structure integrated with the inner sleeve, wherein: the first durometer of the inner layer provides a slip-resistant surface for gripping the therapy delivery element; and the second durometer of the outer layer, the at least one compression member, and the reinforcing structure provide a protective layer to inhibit damage to the therapy delivery element from over-tightening of the suture material.
