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.
