Abstract
Abstract A process for producing a medical electrode. A coil of conductive metal is slid over a tubular insulative substrate. The spaces between individual turns of the coil are backfilled with an insulative plastic. The backfilled plastic is thereafter etched away from and off of the exterior of the metal coil by means of a gas plasma.
