Multi-durometer reinforced suture sleeve
First Claim
1. 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 radially outside the inner layer, the outer layer having a second durometer greater than the first durometer; 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 and the reinforcing structure provide a protective layer to inhibit damage to the therapy delivery element from over-tightening of the suture material.

Abstract
Suture anchors for securing therapy delivery elements, such as stimulation leads or catheters, within a living body. The suture anchor includes an inner sleeve constructed with an inner layer of a softer, more pliable material that easily conforms to the therapy delivery element to reduce slippage and an outer layer constructed from a harder, stiffer durometer material that protects the therapy delivery elements from damage due to over-tightening the tie down sutures. A suture material located in the suture groove is tensioned to apply a radial compressive force. The reinforcing structure spreads the radial compressive force along a greater surface area of the therapy delivery element.

7. A suture anchor configured to secure a therapy delivery element with respect to a living body, the suture anchor comprising:
-
a deformable anchor body including; a primary lumen sized to receive the therapy delivery element; and at least one suture groove adapted to receive a suture material; an inner sleeve disposed within the primary lumen, the inner sleeve including an inner sleeve lumen substantially aligned with the primary lumen, the inner sleeve including an inner layer including a first material of a first durometer, and an outer layer radially outside the inner layer, the outer layer including a second material of a second durometer greater than the first durometer; and a reinforcing structure disposed around the inner layer of the inner sleeve, wherein; the first material of the inner layer provides a slip-resistant surface for gripping the therapy delivery element; and the second material of the outer layer and the reinforcing structure provide a protective layer to inhibit damage to the therapy delivery element from over-tightening of the suture material. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A suture anchor assembly for securing a therapy delivery element to a desired location within a living body, the suture anchor assembly comprising:
-
a deformable anchor body comprising a primary lumen sized to receive the therapy delivery element; 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 radially outside the inner layer, the outer layer having a second durometer greater than the first durometer; a reinforcing structure disposed within the primary lumen, the reinforcing structure including a braid; and a suture material located in a suture groove on an outer surface of the anchor body, the suture material being adapted to apply a radial compressive force that engages the inner layer of the inner sleeve with the therapy delivery element, 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 and the reinforcing structure provide a protective layer to inhibit damage to the therapy delivery element from over-tightening of the suture material. - View Dependent Claims (16, 17, 18, 19, 20)
