HOCHFREQUENZABLATIONSSYSTEM FÜR HERZGEWEBE |
摘要 |
A system for delivering radiofrequency energy to ablate cardiac tissue comprises a radiofrequency generator and an intravascular catheter. The catheter includes both a radiofrequency ablation electrode and a temperature sensor within its distal end. Delivery of power to the ablation electrode may then be controlled based on electrode temperature using a cascade control system wherein analog temperature controller adjusts the set point to a secondary power controller. Alternatively, power delivered to the patient can be controlled directly based on a power set point. Reuse of the catheter is prevented by a fuse within the catheter which is sensed prier to power delivery and broken prior to disconnection of the catheter. |
