Expandable member for perforation occlusion

Abstract

Lead extraction is the removal of one or more leads from inside the heart utilizing a lead removal catheter having a tubular sheath that is placed in the blood vessel, either subclavian or femoral. The sheath of the lead removal catheter may accidentally tear or perforate the blood vesselas it is advanced over the lead toward the heart. Such an occurrence must be dealt with quickly to prevent harm to the patient or subject. An expandable member, such as a balloon, attached to the exterior of the sheath of a lead removal catheter can be deployed temporarily adjacent the perforation in the vessel wall. Inflation of the balloon not only stops (or substantially stops) the bleeding, but, upon inflation, the balloon may include one or more channels that allow blood to continue to flow through the channel(s) until the blood vessel perforation can be repaired.
