The catheter may include an expandable member having a plurality of electrodes, where each electrode is in association with at least one contact sensor and at least one light emitting element. Light is emitted in response to the contact of the contact sensor with the tissue to be ablated. A light sensor disposed centrally to the catheter gathers light emitted from the light emitting elements and sends a signal to a system controller for display.2/4 30--, 38 34 42i 20 463 36 2 40 42 40 6~38 34 FIG.2 30 38/3 42 44443 24 42 40 46 38 34 FIG. 3
