A bipolar cardiac vein lead and method of assembly is provided wherein the lead includes a flexible coil anode electrode such that the lead may be advanced through a tortuous pathway. The coil electrode is coupled to a conductor using a method of assembly that minimizes or eliminates rigid components, maintaining flexibility of the distal lead end. Multi-polar cardiac vein leads may include multiple flexible coil electrodes to achieve pacing and/or sensing in the left atrium and the left ventricle or at multiple left heart sites.

Cardiac vein lead with flexible anode and method for forming same

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.

Screw-in lead

A cardiac pacing lead having a plurality of individually insulated conductors arranged as a multifilar coil. The lead includes a connector assembly and a ring electrode assembly, each of which are optimized for use in conjunction with conductors arranged in the form of a multifilar coil. The connector assembly takes the form of an in-line connector having a plurality of linearly arranged connecting surfaces, each coupled to one of the conductors in the multifilar coil. The ring electrode assembly is constructed such that it displays the same outer diameter as the pacing lead. In both assemblies, conductors are coupled by means of welds, rather than by crimping or swaging.
