Abstract
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.
