摘要： A cardiac pacing lead for endocardial use, having a pacing electrode which takes the form of a tapered, conical helix extending from the distal end of the lead. The helix is used to attach the distal end of the lead to heart tissues. The tapered shape of the helix facilitates passage of the lead through the venous system and through the tricuspid valve. Rotation of the fixation helix is accomplished by means of rotation of a coiled conductor extending the length of the lead, in conjunction with rotation of a stylet, passing down the conductor. The stylet is fixedly mounted with respect to the coiled conductor at both the proximal and distal ends of the lead.
