    Abstract: A method and system for presenting information representative of lesion formation is provided. The system comprises an electronic control unit (ECU). The ECU is configured to acquire a value for an ablation description parameter and/or a position signal metric, wherein the value corresponds to a location in the tissue. The ECU is further configured to evaluate the value, assign it a visual indicator of a visualization scheme associated with the parameter/metric corresponding to the value, and generate a marker comprising the visual indicator such that the marker is indicative of the acquired value. The method comprises acquiring a value for the parameter/metric, and evaluating the value. The method further includes assigning a visual indicator of a visualization scheme associated with the parameter/metric corresponding to the value, and generating a marker comprising the visual indicator.

    Abstract: A system that automatically detects a myocardial barotrauma (i.e., tissue pop) event so that proper post-procedure care can be given includes an electronic control unit (ECU), a computer-readable memory coupled with the ECU, and detection logic stored in the memory configured to be executed by the ECU. The detection logic is configured to receive a signal generated by an electro-acoustic transducer related to acoustic activity within the patient, monitor the signal for a pre-determined indication of a barotrauma event, and output a notification when the pre-determined indication is detected. The transducer can be integrated with an extra-body patch that includes one or more electrodes for use with a medical device navigation system.

    Abstract: An ablation catheter is provided for ablating internal tissue of a patient. The catheter includes a distal end that is adapted to be inserted into a body cavity relative to a desired location therein (e.g., within the heart). An ablation electrode is connected relative to the distal end of the catheter for providing ablation energy to patient tissue. A heat sink is provided that is in thermal contact with the ablation electrode. The heat sink, in addition to being in thermal contact with the ablation electrode, is electrically isolated from the ablation electrode. This allows the heat sink to conduct heat away from the ablation electrode without dissipating electrical energy from the electrode. In this regard, the heat sink may prevent build-up of excess heat within the electrode that may result in blood coagulation and/or tissue charring.
