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.

Abstract: The device for hemostatic treatment of a puncture opening following catheterization comprises an elongate tubular penetration member having a longitudinal axis, an internal end, an external end and a passageway therein including at least one longitudinal channel which extends at least a major portion of the distance between the internal and external ends. A pressure gauge is connected by connecting structure to the external end of the penetration member and to the longitudinal channel. A reservoir for hemostatic pharmacon is provided and is connected to the external end of the penetration member. The penetration member is provided with an opening, close to the internal end of the penetration member, for communicating the pressure gauge to the puncture opening.
