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.
L'invention concerne une dérivation de veine cardiaque bipolaire et un procédé d'assemblage. La dérivation comprend une anode à bobine flexible permettant à la dérivation d'avancer dans une voie sinueuse. L'électrode à bobine est couplée à un conducteur à l'aide d'un procédé d'assemblage minimisant ou éliminant les composants rigides, et maintenant la flexibilité de l'extrémité distale de la dérivation. Les dérivations de veines cardiaques multipolaires peuvent comprendre de multiples électrodes à bobines flexibles de stimulation cardiaque et/ou de détection dans l'oreillette gauche et le ventricule gauche, ou au niveau de multiples sites cardiaques du côté gauche.
