Abstract:
An arrangement for use with a power source to electrothermally treat a body, comprising:a manually graspable handle having a handle height dimension, a handle width dimension, and a handle thickness dimension, one of the dimensions being a greatest handle dimension; a catheter having a substantially straight portion and a longitudinal axis that runs through the substantially straight portion, the substantially straight portion including a first electrode and a second electrode that are insulated from one another and that are jointly inserted into the body, the first and second electrodes having longitudinal axes that coincide with the longitudinal axis of the substantially straight portion, the second electrode having a width that is at least as large as the width of the first electrode; means for joining the catheter to the handle; and means for connecting both electrodes of the catheter to the power supply, wherein the substantially straight portion has a length that is at least as large as the greatest handle dimension, and has a ratio of the length to the width of the second electrode that is large, and wherein the catheter has a tip and the first electrode is disposed at the tip, the first electrode having a length that is substantially smaller than the length of the second electrode.
