Patent ID: 7699829

Claim:
A medical device, comprising: a catheter with a distal end and a proximal end and at least one catheter lumen extending therebetween; a sensor located at the catheter distal end; and at least two sensor leads, a distal end of each of the sensor leads in electrical communication with the sensor, and a proximal end of each of the sensor leads extending to the catheter proximal end; wherein the sensor includes at least two electrodes, where each electrode is in electrical communication with at least one of the at least two sensor leads, and the electrodes are located at the catheter distal end such that the electrodes contact a target site when the catheter distal end is placed at the target site; wherein each electrode has an end plate with a major axis that is substantially perpendicular to a longitudinal axis of the catheter, and wherein at least a portion of the end plate overhangs the distal end of the catheter.
