Suture sleeves having exterior surface tear resistance
First Claim
1. A suture sleeve for securing an implantable lead with at least one suture, the suture sleeve comprising:
- a tubular body having a proximal end portion and a distal end portion;
a lumen within the tubular body extending from the proximal end portion to the distal end portion, the lumen sized to receive the implantable lead;
at least one suture receiving area along the tubular body, the at least one suture receiving area respectively defining at least one exterior surface respectively within at least one channel that extends around a circumference of the tubular body;
a tear resistant feature extending only along the at least one exterior surface within the at least one channel, the tear resistant feature comprising a textured pattern configured to resist initiation of a tear in the at least one exterior surface from the at least one suture; and
an inner surface within the lumen, the inner surface configured to frictionally engage the implantable lead.

Abstract
Various embodiments concern a suture sleeve for securing an implantable lead with a suture. The suture sleeve can comprise a tubular body having a proximal end portion, a distal end portion, an exterior surface, and a lumen, the lumen sized to receive the implantable lead. The suture sleeve can further comprise a suture receiving area along the tubular body, the suture receiving area within a channel that extends around a circumference of the tubular body. An exterior surface of the suture receiving area can comprise a tear resistant feature. The tear resistant feature can be configured to resist initiation of a tear in the exterior surface from the suture. The lumen can comprise an inner surface configured to frictionally engage the implantable lead.

18. A method of making a suture sleeve for use with at least one suture for securing an implantable lead, the method comprising:
-
forming a tubular body having a proximal end portion, a distal end portion, a lumen sized to receive the implantable lead, an inner surface within the lumen, and at least one channel around the circumference of the tubular body, the at least one channel comprising at least one exterior surface, the at least one channel sized to accommodate the at least one suture within the at least one channel, respectively; and forming a textured pattern on the at least one exterior surface in the at least one channel, the textured pattern providing a tear resistance property of the at least one exterior surface, wherein the textured pattern is only formed on the at least one exterior surface within the at least one channel. - View Dependent Claims (19, 20)
