1. A system for displaying contact between a catheter and a tissue in a body, comprising:
- a catheter comprising a distal portion and a sensor; and
a controller in operable communication with the sensor and configured to receive as input therefrom a reading indicative of a degree of contact between the distal portion and the tissue, to calculate a degree of contact between the distal portion of the catheter and the tissue, and to provide an output indicative of the degree of contact.

Abstract
A system and method for assessing and displaying a degree of contact between a sensor, an electrode, and tissue in a body is provided. Values for the sensor are read, and a degree of contact is calculated. This degree of contact is displayed to a clinician in a variety of ways to indicate the degree of contact to the clinician. The system and method find particular application in ablation of tissue by permitting a clinician to create lesions in the tissue more effectively and safely.
