Abstract: A balloon catheter for an intravascular catheter system includes a cryogenic balloon that is formed from a blend of polyurethane and polyamide block copolymer. The percentages of polyurethane and polyamide block copolymer can vary. For example, the cryogenic balloon can be formed from greater than 50% polyurethane and less than 50% polyamide block copolymer; greater than 75% polyurethane and less than 25% polyamide block copolymer; or approximately 85% polyurethane and approximately 15% polyamide block copolymer. Additionally, a ratio of a change in inflation pressure (in psi) to a change in outer diameter (in mm) of the cryogenic balloon, and a ratio of outer diameter (in mm) of the cryogenic balloon to inflation pressure (in psig) can be varied to form the desired cryogenic balloon.

Abstract: A cryoablation catheter system comprises a cryoablation catheter having a shaft, a guidewire lumen member and an expandable balloon attached to the shaft and the guidewire lumen member, and an auxiliary device configured for use in combination with the cryoablation catheter, the auxiliary device including a location sensor configured to provide a sensor output indicative of a location of the location sensor within a localization volume responsive to a localization field. A user-accessible relative position indicator is located on one or both of the cryoablation catheter and the auxiliary device and is configured to provide an indication of a relative position of the cryoballoon and the location sensor.

Abstract: A cryoablation catheter comprises a catheter shaft, a guidewire lumen disposed within the catheter shaft, a cryoballoon having a first end connected to the catheter shaft and an opposite second end connected to the guidewire lumen, the cryoballoon configured to transition between a deflated state and an inflated state, the cryoballoon having a maximum circumference in the inflated state, a proximal electrode array having a plurality of proximal electrodes arranged around the cryoballoon and located proximally of the maximum circumference of the cryoballoon, and a distal electrode array having a plurality of distal electrodes arranged around the cryoballoon and located distally of the maximum circumference of the cryoballoon. The cryoablation catheter has no electrodes located at the maximum circumference of the cryoballoon.
