Third, the distal electrode portion includes at least two ring electrodes and the proximal shock electrode includes at least two larger surface coil electrodes.

They implement spiral electrodes of large surfaces, supporting the delivery of high currents.

The tube either has holes or a longitudinal slit so that the coiled electrodes can protrude from the central cavity of the tube.

The electrode catheter is made from joining a tube with 4 to 256 wire leads having terminal ends (2) and coiled electrodes (10).

The present invention relates to coiled electrode assemblies having conductive tabs, methods of attaching the conductive tabs to the coiled electrode, and electrochemical cells employing such assemblies.

The piles deliver 3,6 V. They are cylindrical, of format 1,2AA to D, with electrodes spiral for the applications of power or concentric (winds) for the prolonged discharges.
