Abstract
Maximum HF current is initially introduced into tissue at a pre-specified maximum coagulation voltage. In this initial state, the tissue behaves in accordance with Ohm's law and can take up the maximum energy per unit of time. After the tissue has changed from an initial state to a state in which the tissue impedance or resistance is voltage-dependent, the HF parameters are selected such that the maximum possible energy input per unit of time is set.
