System and method for controlling delivery of ablation energy to tissue
First Claim
1. A system for controlling delivery of ablation energy from an ablation catheter to tissue in a body, comprising:
- 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; and
generate a first control signal, responsive to the determined value of the characteristic, to control an amount of energy delivered from the ablation delivery element to the tissue;
wherein the amount of energy varies continuously in response to a change in the determined value of the characteristic when the determined value of the characteristic is between a first threshold value and a second threshold value.

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.
