ABSTRACT:
The cryo-ablation catheter comprises a generally tubular body having a proximal end and a distal end. The distal end includes a hollow closed head made of a thermally conductive material. A pressure line is received in and extends in the catheter from a location near the proximal end to a location near the head. The catheter includes a discharge channel extending from the head to the proximal end. The pressure line is made of a synthetic material which has, compared to metal, a low modulus of elasticity and a high thermal resistance coefficient.
