Sutureless lead retention features
First Claim
1. A system comprising:
- a lead having a lead body and at least one electrode, wherein the lead body is configured for advancement into an epidural space through a needle; and
a coiled retention feature disposed along the lead body proximal to the at least one electrode,wherein the coiled retention feature comprises an unexpandable coil wrapped around a section of the lead body passable through the needle,wherein the coiled retention feature is formed from or coated with a material configured to promote tissue in-growth, andwherein the coiled retention feature is configured to assist in atraumatically anchoring the lead to nearby tissue within the epidural space by frictional forces when the lead is positioned in the epidural space.

Abstract
A system includes a lead having a lead body and at least one electrode; and a retention feature disposed along the lead body proximal to the at least one electrode and configured to assist in atraumatically anchoring the lead to nearby tissue when the lead is positioned in the body. A system includes a lead having a lead body and at least one electrode; and a coiled retention feature disposed along the lead body proximal to the at least one electrode and configured to assist in anchoring the lead to nearby tissue when the lead is positioned in a body. A lead for stimulating a target neural tissue includes an elongate body; at least one electrode disposed along the elongate body; and a passive retention feature disposed along the lead body proximal to the at least one electrode and configured to assist in anchoring the elongate body to tissue near the target neural tissue.
