Self-clamping anchoring sleeve
First Claim
Patent Images
1. A method for anchoring an implantable lead to a blood vessel, comprising the steps of:
- (a) providing a lead, said lead having a proximal end and a distal end, an electrode adjacent said distal end and a plug adjacent said proximal end, said electrode being in electrical communication with said plug;
(b) inserting said distal end into said blood vessel at an anchoring point such that at least a distal portion of said lead lies within said blood vessel and a proximal portion lies outside said blood vessel;
(c) providing a sleeve separate from said lead said sleeve comprising a resilient helix having an unbiased, coiled shape;
(d) at least partially uncoiling the sleeve;
(e) placing the uncoiled sleeve adjacent the blood vessel at the anchoring point; and
(f) wrapping the sleeve around the blood vessel and lead while allowing the sleeve to partially resume its unbiased, coiled shape until it engages the lead and the blood vessel.

Abstract
A cardiac stimulator lead and sleeve for anchoring the lead at its point of entry into a vein. More particularly, the present invention comprises a helical coil made of a resilient material that is capable of being uncoiled and wrapped around the lead and/or the vein such that it is biased to resume its fully coiled state and thereby frictionally engages the vein and or lead and functions as an anchoring device for the lead.
