Abstract: A self-anchoring helical wire structure electrode for energy conduction to or from a tissue target in a body, made of at least one wire rope consisting of biocompatible and conductive wire, and enclosing a hollow core within an inner diameter and having a longitudinal axis, an outer diameter and two ends, being flexible for self-bending in any direction up to 180 degrees on said longitudinal axis, and secured by being capable of self-forming a bunching anchor wider than the insertion channel when injected while its dispenser is substantially stationary.

Abstract: A head design that reduces wear at the leading and trailing edges where the tape contacts the head while minimizing any adverse effects on the performance of the head. In one embodiment of the invention, a localized layer of wear resistant material is formed on the leading edge where the tape contacts the head before passing over the head recording surface. In a second embodiment, the leading edge is formed as wear resistant material embedded in the head structure adjacent to the recording surface. And, in a third embodiment, the leading edge is formed as a wear resistant material strip affixed to the side of the head structure. For each embodiment, the wear resistant material may also be applied in the manner described to the trailing edge where the tape may also contact the head after passing over the recording surface.
