Claim 0:
1. A cryo-fixation lead extraction device comprising: a lead extraction catheter having longitudinally spaced proximal and distal catheter ends and an elongate catheter lumen; a liner having longitudinally spaced proximal and distal liner ends and an elongate liner lumen, the liner lumen extending entirely between the proximal and distal liner ends and being configured to selectively accept at least part of a lead being extracted longitudinally therethrough, at least a portion of the liner being located a chosen one of circumferentially within and circumferentially surrounding the catheter lumen; and at least one cryogen supply line extending longitudinally through at least a portion of the liner lumen, the cryogen supply line being configured to place a cryogen fluid source in operative proximity to the proximal liner end in fluid communication with the distal liner end, the cryogen supply line being configured to selectively generate a patient tissue frozen zone adjacent the distal catheter end, wherein the at least one cryogen supply line is affixed to an inner surface of the liner lumen; and a cutting feature located adjacent the distal catheter end, the cutting feature configured to selectively mechanically cut into at least a portion of the patient tissue frozen zone adjacent the lead being extracted.
