Abstract
A vascular snare system and method for extracting elongated objects such as pacemaker pacing leads or defibrillator leads from the vasculature of a patient are provided. The system utilizes a sheath having a lumen through which two wire elements are deployed to snare and extract a lead. Each wire element has a magnet disposed at its distal end. The wire elements may be manipulated to form a closed loop transversely around a midsection or central portion of the body of the lead by coupling the magnets to each other. The wire elements may then be utilized to extract the lead from the vasculature of the patient through the lumen.
