Abstract
Official abstract text for this publication.
Tissue ablation systems and methods are provided, wherein a cardiac catheter 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 computed ablation volume. The monitor may dynamically display the progress of the ablation by varying the visual indication.
First claim
Opening claim text (preview).
What is claimed is: 1. An ablation apparatus, comprising: a flexible catheter, having a proximal segment, a distal end for insertion into a body cavity of a living subject and a distal tip, which is disposed at the distal end of the catheter and is configured to be brought into contact with a tissue in the body cavity, the flexible catheter further comprising a joint connecting the proximal segment to the distal end, the flexible catheter being configured to bend at the joint to d…
