Abnormal pulse delivery protection for pulsed field ablation systems

Abstract

One aspect provides a pulsed field ablation system including a bridge circuit configured to deliver bipolar and biphasic voltage pulses to a catheter. An asynchronous current monitor circuit electrically coupled the bridge circuit. An electronic processor is coupled to the bridge circuit and the asynchronous current monitor circuit. The electronic processor is configured to determine whether an abnormal pulse delivery is present in the bridge circuit and control the bridge circuit to deliver therapeutic current to the catheter when the abnormal pulse delivery is not present. The electronic processor is also configured to inhibit the bridge circuit from delivering therapeutic current to the catheter when the abnormal pulse delivery is present.
