Abstract

Various aspects of the present disclosure are directed toward methods, apparatuses, and systems that include an implantable medical device comprising an implantable lead, a suture sleeve having an interior surface defining a lumen of the suture sleeve that receives the implantable lead, and an engagement feature configured to non-removeably secure the suture sleeve to the implantable lead.

Claims

1. An implantable medical device comprising:

an implantable lead having a distal region, a proximal region, and an intermediate region therebetween;

a suture sleeve having an interior surface defining a lumen of the suture sleeve, the lumen receiving the implantable lead, the suture sleeve comprising an exterior surface that defines at least one suture receiving track and at least one indentation along the interior surface of the suture sleeve; and

an engagement feature arranged on the implantable lead and configured to non-removeablely secure the suture sleeve to the implantable lead and the engagement feature comprises at least one radial projection having an upper surface, a lower surface, and sidewalls, the upper surface and the sidewalls being configured to provide a mechanical stop for the suture sleeve and engage the at least one indentation to secure the suture sleeve to the implantable lead.

2. The medical device of claim 1, wherein the at least one radial projection comprises opposing sidewalls configured to engage the at least one indentation to secure the suture sleeve to the implantable lead.
