Abstract

An improved suture sleeve for a lead body includes an elongated tubular sleeve body formed of a compressible elastomeric material wherein a surface of the lumen has a relatively rough texture formed by a particulate or fibrous media embedded therein.

Claims

1. An improved suture sleeve for a lead body, comprising an elongated tubular sleeve body formed of a compressible elastomeric material and including a lumen extending through the suture sleeve body, the lumen including a surface having a relatively rough texture formed by a particulate or fibrous media embedded therein.

2. The suture sleeve of claim 1, wherein the surface of the lumen is formed in part by an insert in which the particulate or fibrous media is embedded.

3. The suture sleeve of claim 2, wherein the insert is formed of a compressible elastomeric material similar to the compressible elastomeric material from which the tubular sleeve body is formed.

4. The suture sleeve of claim 1, wherein the lumen surface includes a layer of a pressure-activated adhesive.

5. The suture sleeve of claim 1, wherein the lumen surface includes a layer of a fluid-activated adhesive.

6. The suture sleeve of claim 1, wherein the particulate or fibrous media comprises irregular shaped and differing sized particles.

7. The suture sleeve of claim 1, wherein the particulate or fibrous media comprises radiopaque particles.

8. The suture sleeve of claim 1, wherein the particulate or fibrous media comprises non-water soluble powders or grits, which are selected from the group consisting of polyurethane, polysulfone, polyimide, silica, ceramic, platinum, stainless steel, tantalum, and titanium.

9. The suture sleeve of claim 1, wherein particulate or fibrous media comprises generally spherical particles.

10. The suture sleeve of claim 9, wherein the generally spherical particles are selected from the group consisting of platinum, stainless steel, tantalum, and titanium.

11. The suture sleeve of claim 1, wherein the particulate or fibrous media comprises fibers.

12. The suture sleeve of claim 1, wherein the particulate or fibrous media comprises particles having a hardness greater than that of the compressible lastomeric material.
