Left ventricular access lead for heart failure pacing
First Claim
1. A method of pacing a patient'"'"'s heart, comprising the steps of:
- a) transveineously inserting and positioning a lead having a proximal end, a distal end, and a lumen, through a coronary sinus and into a coronary vein of a patient'"'"'s heart, the coronary vein being one of a posterior vein, an anterior vein, a middle vein and a great vein, the lead including an electrode surface disposed on the lead in a zone located near the distal end and a transition ring for transferring a rotational force fixed within the lead;
b) coupling said electrode surface to a means for pacing the patient'"'"'s heart; and
c) applying a pacing pulse from said means for pacing to said electrode surface via said lead to thereby pace the left ventricle of the patient'"'"'s heart.

Abstract
An elongated monopolar or bipolar coronary vein lead having a reduced outer diameter and especially adapted to be advanced into a selected coronary vein for delivering a pacing signal to a predetermined region of a patient'"'"'s heart, such as the left ventricle. A method of using the lead for pacing a patient'"'"'s heart in the treatment of heart failure is also described. The method for pacing the heart includes advancing the coronary vein lead through both the coronary sinus and into a selected coronary vein of a patient'"'"'s heart, connecting the lead to an electrical pacing source and applying electrical stimulation to a particular chamber of the patient'"'"'s heart via the implanted lead. The lead includes a flexible tip and transition ring that enhances the ability to guide the lead through the coronary veins.
