Suture sleeves having exterior surface tear resistance

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.
