Abstract
Abstract A defibrillation lead for location in a human heart, having an elongated lead body defining a generally straight segment extending from its proximal end and a curved segment extending distally from the straight segment. The curved segment has a sigmoidal configuration including a two or more alternating, generally coplanar curves, and carries an elongated defibrillation electrode extending along its length. A stylet is provided for straightening the curved segment prior to implant.
