Latest Patents

Culp’s patent, “System Configuration for Combined Defibrillator/Pacemaker,” describes features for an implantable cardiac device. The system delivers a multiphase defibrillation waveform and includes measures to limit patient current leakage and protect pacing circuitry from the defibrillator’s high-voltage output. Its dual-channel pacing circuit supports bipolar and pseudo-unipolar pacing. The design can also detect breaks in a defibrillator lead without delivering a shock and use the pacing output stage for high-rate pacing to induce ventricular fibrillation.

Career Highlights

Culp’s documented patent work reflects engineering focused on integrating defibrillation and pacing functions in an implantable system. The disclosed features address device protection, lead monitoring, and flexible pacing operation.
