System and method for controlling delivery of ablation energy to tissue
First Claim
1. A method for controlling delivery of energy to an electrode, comprising:
- delivering an amount of energy to the electrode;
receiving, with a processor, a measurement signal indicative of a first characteristic associated with delivery of the amount of energy to the electrode; and
varying the amount of energy based on the measurement signal.

Abstract
A system for controlling delivery of ablation energy by an ablation catheter to tissue in a body is provided. The system includes an electronic control unit configured to determine, responsive to a measurement signal from the ablation catheter, a value for a characteristic associated with the delivery of ablation energy to the tissue. In one embodiment, the characteristic is the degree of contact between the ablation catheter and the tissue. The unit is further configured to generate a control signal, responsive to the determined value of the characteristic, to control an amount of energy delivered from an ablation delivery element on the ablation catheter to the tissue. The amount of energy varies in response to the determined value of the characteristic when the determined value of the characteristic meets a predetermined condition relative to a threshold value for the characteristic.
