Abstract
A bipolar cutter/coagulator produces a coagulating waveform comprising an aperiodic sequence of damped RF bursts. The inter-burst spacing is pseudo-random, and the intra-burst RF frequency is swept between preset limits. The burst envelopes are uniform, always starting at the same preselected amplitude.
