Claim 9:
10. The cryo-fixation lead extraction system of claim 9, including a cryogen fluid destination, and wherein the cryo-fixation lead extraction device includes
a distal freezing chamber located adjacent the distal liner end and being in fluid communication with the cryogen fluid source via the at least one cryogen supply line, and
at least one cryogen return line extending longitudinally through at least a portion of the liner lumen, the at least one cryogen return line being configured to place the distal freezing chamber in fluid communication with a cryogen fluid destination via the proximal liner end;
the cryogen fluid source, the at least one cryogen supply line, the distal freezing chamber, the at least one cryogen return line, and the cryogen fluid destination collectively comprising a closed cryogen loop preventing passage of cryogen fluid distally from the cryo-fixation lead extraction device; and
the operator interface being operatively connected to at least one of the at least one cryogen return line and the cryogen fluid destination for selectively regulating cryogen fluid flow.
