Claim 12:
13. A cryo-fixation lead extraction liner comprising: 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 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 liner 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 liner 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.
