1. A defibrillation lead for location in a human heart, comprising:
- an elongated lead body having proximal and distal ends, said lead body having a first generally straight segment extending from its proximal end and a second curved segment extending distally from said first segment, said second segment having a sigmoidal configuration comprising a plurality of alternating, generally coplanar curves;
an elongated electrode extending along said second segment;
a first conductor located within said lead body, and coupled to said elongated electrode;
first connector means, coupled to said first conductor, for electrically coupling said elongated electrode to an implantable defibrillator; and
means for straightening said second segment.

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.
