Claim Text:
1. A system for ablating a target tissue during a medical procedure, the system comprising: an elongate flexible catheter adapted to be introduced into a patient during said medical procedure, said catheter including a distal portion; an ablation head disposed at said distal portion of said catheter, said ablation head adapted to contact with said target tissue during said medical procedure; a force sensor operatively coupled with said ablation head for measurement of a contact force exerted on said ablation head, said force sensor configured to output a signal in response to said contact force; a power source operatively coupled with said ablation head for energization of said ablation head; and a control system configured to receive said signal from said force sensor and to produce a sequence of contact force values acquired over a time period of energization based on said signal output by said force sensor for calculation of a force-time integral that is utilized by said control system to control ablation of said target tissue.
