Transvenous cardiovascular integrated lead anchoring sleeve, protector, and permanent lead introducer stop gap

Abstract

A body implantable lead having an anchoring sleeve slideably affixed thereto. The anchoring sleeve is generally cylindrical in shape, having a cylindrical lumen through which the main body of the body implantable lead passes. Since the lumen within the anchoring sleeve is smaller than the diameter of the electrode fixation device at the distal end and the electrical connector at the proximal end of the body implantable lead, the anchoring sleeve is fixedly, though slideably attached to the body implantable lead. The anchoring sleeve is molded of a body compatible material such as silicone or polyurethane. Small serrations of body compatible material within the lumen of the anchoring sleeve generate sufficient friction such that the anchoring sleeve does not slide along the body implantable lead from the sheer force of gravity. The distal end of the anchoring sleeve is tapered or otherwise suitably shaped to permit it to occlude a permanent lead introducer and/or blood vessel during implantation. A groove about the body of the anchoring sleeve permits ready attachment through suturing.
