Claim 0:
1. An endovascular near critical nitrogen based cryoablation system for creating a lesion along an interior wall of a heart, the system comprising:
a near critical nitrogen pressure generator;
a near critical nitrogen cooler for cooling near critical nitrogen;
a near critical nitrogen based endovascular cryoablation catheter in fluid communication with the generator; and
a controller operable to modify a flow rate of the near critical nitrogen thereby controlling an ablative power delivered from a distal treatment section of the catheter to the interior wall of the heart, wherein the distal treatment section is configured to create a continuous transmural lesion;
wherein the cryoablation catheter comprises a tube bundle comprising a plurality of first tubes, each of which is individually surrounded by an outer tube and defining a gap between the outer tube and the first tube, and wherein the gap is filled with a thermally conducting fluid.
