ABSTRACT:
A medical electrical lead system featuring a medical electrical lead which features an improved anchoring sleeve. The medical electrical lead and anchoring sleeve cooperate with an introducer sheath to minimize the flow of blood through the introducer sheath during the introduction of the lead into the blood vessel. Specifically, the lead has a connector assembly, a conductor attached thereto and an electrode electrically coupled to the conductor. An insulative sleeve covers the conductor and an annular anchoring sleeve is movably positioned over the insulative sleeve. The anchoring sleeve has a distal end and a proximal end and further has an annular or circumferential seal within the inner lumen at the distal end. The distal end is further tapered along its exterior portion. The taper of the distal end cooperates with an introducer sheath to provide a seal between the outer portion of the anchoring sleeve and the introducer sheath. The circumferential seal on the same distal end cooperates with the medical electrical lead to create a seal between the anchoring sleeve and the medical electrical lead. In such a manner, a hemostatic seal is accomplished such that blood will not flow through the introducer sheath while the lead is within the introducer sheath and being positioned into the body.
