Abstract: A defibrillation catheter having a connection from an electrode to an infeed conductor in the mid-point area of the electrode. The mid-point current feed provides for a voltage drop from the center of the electrode to its ends, which minimizes extreme electrical fields which normally develop at the electrode ends. The coil resistance is selected to further optimize the field distribution so as to allow a large passage of defibrillation current without cell damage.
