Claim:
1. An ablation control system, comprising: a measurement circuit to determine a contact state between an ablation electrode and a tissue to be ablated by measuring a degree of electrical coupling between the ablation electrode and the tissue to be ablated; a clock to measure a time period during which ablative energy is applied by the ablation electrode to the tissue to be ablated; a lesion analysis processor for estimating a volume of a lesion forming in the tissue to be ablated as a function of at least three interdependent variables, wherein the at least three interdependent variables are inversely related for a preset volume of the lesion forming in the tissue to be ablated, and wherein the at least three interdependent variables comprise: a controller coupled to the lesion analysis processor and configured to control an ablation power source to create a lesion of the preset volume based on information provided by the lesion analysis processor.
