- 22 Tissue ablation systems and methods are provided, wherein a cardiac catheter 5 incorporates a pressure detector for sensing a mechanical force against the distal tip when engaging an ablation site. Responsively to the pressure detector, a controller computes an ablation volume according to relationships between the contact pressure against the site, the power output of an ablator, and the energy application time. A monitor displays a map of the heart which includes a visual indication of the 10 computed ablation volume. The monitor may dynamically display the progress of the ablation by varying the visual indication. 14/12/10,va 18990 spcci.doc.22 cv, |
