摘要:
An electrosurgical device having a distal tip for creating a lesion on tissue includes a first electrode and a second electrode that are parallel for the delivery of RF energy to tissue. A sensor electrode is provided parallel to and spaced away from the first electrode a different distance than the second electrode. When the sensor electrode and at least one of the first and second electrodes are in contact with tissue, The electrosurgical device can perform at least one of the following: ablating tissue, and sensing at least one selected from the group of voltage, tissue impedance, electrical conduction, conduction time, conduction velocity, and signal phase angle.
