Abstract:
1. A device for monitoring luminal esophageal temperatures in a patient, comprising: a probe adapted to be inserted into an esophagus of the patient, the probe extending between a proximal end and a distal end; a plurality of electrodes and a plurality of temperature sensors extending along a length of a longitudinal axis of the probe, the length along which the plurality of electrodes and the plurality of temperature sensors extend being selected to enable continuous monitoring of temperatures in the area of an esophagus subject to formation of atrial-esophageal fistulas during a cardiac ablation; a temperature sensor interface coupled to the probe remote from the distal end of the probe, wherein the temperature sensor interface is in communication with the plurality of temperature sensors; an electrode interface coupled to the probe remote from the distal end of the probe, wherein the electrode interface is in communication with the plurality of electrodes; a controller having software executing; wherein the electrode interface is connected to the controller and the controller is adapted to receive signals from the electrode interface; wherein the temperature sensor interface is connected to the controller and the controller is adapted to receive signals from the temperature sensor interface; a video monitor in communication with the controller; wherein the controller is configured to display on the monitor a three-dimensional anatomic map of the esophagus based at least in part on the signals received from the electrode interface; wherein the controller is configured to display on the monitor a three-dimensional thermal map of the esophagus based at least in part on the signals received from the temperature sensor interface; and wherein the three-dimensional thermal map is overlaid on the three-dimensional anatomic map.
