Patent ID: 8454587

Claim:
A cryoablation system comprising a cryotreatment catheter and a coolant console having: a coolant supply; a condenser in fluid communication with the coolant supply; a compressor in fluid communication with the coolant supply, the compressor having an inlet line and an outlet line, the outlet line branching into a first segment providing a fluid path to the coolant supply and a second segment providing a fluid path to the cryotreatment catheter; wherein at least a portion of the inlet line and a portion of the outlet line pass through the condenser upstream of the cryotreatment catheter; a heat exchanger thermally coupling at least a portion of the inlet line to at least a portion of the output line of the compressor upstream of the catheter, the first and second segments of the compressor outlet line branching downstream of the condenser and upstream of the heat exchanger; and a first pressure regulator disposed between the coolant supply and the condenser.
