Key Points
- To design and assess a novel catheter ablation system using a short-time capacitive power source to deliver high voltages without arcing or barotrauma.
- Engineered an ablation system combining a short-time capacitive power source with a specialized catheter designed to suppress arcing.
- Tested and compared the electrical delivery performance against a conventional ablation system in an in vitro saline tank model.
- Enabled substantial increases in delivered voltage, current, and total energy compared to the conventional system without triggering electrical arcing.
- Successfully prevented fulguration, avoiding the formation of shockwaves that cause mechanical barotrauma.
