IMPLANTABLE MEDICAL LEAD AND METHOD OF MANUFACTURE

摘要

ABSTRACT An implantable electrical lead having coiled conductors and a method of manufacturing the lead. The method generally comprises: (a) assembling, along an outer surface of inner elongate structure (56; 71) defining an longitudinal axis, at least one elongate conductor (50; 76) and at least one twist ring (52; 70) holding a first portion of the elongate conductor; (b) fixing) a second portion of the elongate conductor to the outer surface of the inner elongate structure (e.g., with a second twist ring bonded to the inner elongate structure, the second portion of the elongate conductor being spaced along the length of the elongate conductor from the first portion; and (c) rotating the twist ring (52, 70) relative to the longitudinal axis of the inner elongate structure to coil the at least one elongate conductor.
