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 tubular shaft having a shaft distal end and a shaft lumen, a tubular guidewire lumen member extending within the shaft lumen and forming a guidewire lumen extending between the guidewire lumen member proximal end and the guidewire lumen member distal end, an expandable cryoballoon having a proximal portion attached to the shaft distal end and a distal portion attached to the guidewire lumen member distal end, and a cryoablation catheter location sensor configured to generate a cryoablation location signal when in the cryoablation catheter location sensor is within a magnetic localization field.
