LEAD AND CATHETER ASSEMBLY
First Claim
1. A method of accessing lateral branch veins of the coronary sinus with a pacing lead and guide catheter assembly, said guide catheter having an open lumen extending therethrough and a distal end provided with a pre-formed guide curve, said pacing lead having a distal end provided with a first curve and a second curve extending proximally from the first curve, the method comprising:
- inserting the guide catheter into an access vessel of the heart;
advancing the guide catheter along the access vessel to the coronary sinus;
inserting the pacing lead into the guide catheter lumen;
advancing the pacing lead distally through the guide catheter lumen;
aligning the first curve of the pacing lead with a plane pre-determined by the orientation of the guide curve; and
advancing the first curve of the pacing lead into one of the lateral branch veins of the coronary sinus.

Abstract
A method of accessing lateral branch veins of the coronary sinus with a pacing lead and guide catheter assembly. The guide catheter has an open lumen extending therethrough and a distal end provided with a pre-formed guide curve, while the pacing lead has a distal end provided with a first curve and a second curve extending proximally from the first curve. The guide catheter is inserted into an access vessel of the heart and advanced along the access vessel to the coronary sinus. The pacing lead is inserted into the guide catheter lumen and advanced distally through the guide catheter lumen. The pacing lead is rotated by advancing the second curve of the pacing lead through the guide curve to align the first curve with a pre-determined plane. The first curve of the pacing lead into one of the lateral branch veins of the coronary sinus.
