ABSTRACT:
An implantable electrical lead having a lead body fabricated of a first, inner tube and a second, outer tube, the first, inner tube, mounted slideably within the outer tube, the outer tube overlapping the inner tube along at least a portion of its length; and having a conductor extendible along a portion of its length, mounted within and extending along the first and second tubes with the extendible portion of the conductor extending within a region in which the outer tube overlaps the inner tube and having an electrode mounted to a distal portion of the lead body, coupled to the conductor. The inner and outer tubes are preferably approximately the same length, and the extendible portion of the conductor preferably extends along a majority of its length. The extendible conductor may be a coiled conductor provided with an insulative coating.
