  • Patent number: 10098686
    Abstract: A cryogenic ablation catheter includes a catheter shaft, a balloon and a connector respectively at the catheter shaft proximal and distal ends, a refrigerant delivery tube assembly including a refrigerant delivery tube translatable within the catheter shaft lumen, and a refrigerant delivery element with an outlet located inside the balloon which directs refrigerant outwardly against the balloon at different axial positions as it translates. A cryogenic balloon ablation system includes the cryogenic ablation catheter, a catheter coupler mating with the connector, a linear motion assembly, and a connection line fluidly coupled to a refrigerant fluid source for supplying refrigerant fluid to the refrigerant delivery tube.
    Type: Grant
    Filed: July 15, 2016
    Date of Patent: October 16, 2018

  • Patent number: 9050073
    Abstract: A cryogenic ablation catheter includes a catheter shaft, a balloon and a connector respectively at the catheter shaft proximal and distal ends, a refrigerant delivery tube assembly including a refrigerant delivery tube rotatable within the catheter shaft lumen, and a refrigerant delivery element with an outlet located inside the balloon which directs refrigerant outwardly against the balloon at different rotary positions as it rotates. A cryogenic balloon ablation system includes the cryogenic ablation catheter, a catheter coupler mating with the connector, a motor including a rotatable hollow motor shaft, and a delivery line fluidly coupled to a cryogenic gas source for supplying cryogenic gas to the refrigerant delivery tube. At least one of the refrigerant delivery tube and the delivery line passes at least partway through the hollow motor shaft. The coupling tip of the connector and the refrigerant delivery tube rotate with the motor shaft.
