Abstract
A system for lead removal of both heart pacemaker leads and cardioverter-defibrillator endocardial leads comprising a flexible coil of flattened ribbon. Preferably, the ribbon is comprised of polyethylene or another suitable biologically compatible material. At a distal end of the coil, a cutting surface may be provided, such as a chisel-like edge at the distal end of the coil. A handle may be provided for twisting the coil onto the lead. The coil should be at least partially radiopaque or provided with a surface which is radiopaque so that its use may be observed in the body by fluoroscopy or other suitable means.
