ABSTRACT:
An extractor is provided for safely and easily removing an implanted lead such as a cardiac pacing lead from a patient. The extractor accomplishes a method that includes imparting a wedging condition to an implanted lead at a distal location thereof, such as a location at or near an electrode implanted in an atrium or ventricle of a heart, which wedging condition permits a pulling force to be transmitted along the length of the extractor and to the implanted electrode location, thereby avoiding the need to impart any substantial pulling forces along length of the lead itself. The extractor includes a tube and a line which move with respect to each other to impart the wedging condition onto a distal portion of the implanted lead.
