| Zusammenfassung: | 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. |
