Abstract
In an electrosurgical device, a RF generator is pulse modulated during coagulating procedures. Pulse repetition rate is varied allowing the occasional interjection of relatively wide pulses of RF energy while still allowing sufficient cooling time to avoid cell volatilization. The result is efficient coagulation with minimal cutting.
