Method and apparatus for placing a coronary sinus/cardiac vein pacing lead using a multi-purpose side lumen
First Claim
Patent Images
1. A method for positioning an implantable medical electrical lead body in a cardiac vein, comprising:
- delivering a medium out through a distal opening of an open lumen of a lead body of the lead;
the open lumen extending generally parallel to a separate lead body conductor lumen, which extends to a distal end of the lead body, and including a distal opening positioned in proximity to the distal end of the lead body, the distal opening directing the medium in a distal direction generally parallel to a distal end of the lead body; and
fixing the distal end of the lead body within the vein by means of the delivered medium.

Abstract
A medical electrical lead, which may be useful in coupling an implantable medical device, is comprised of an elongate body having first and second spaced apart lumens. A conductor and an electrode are associated with the first lumen, and the second lumen is multi-purpose. The second lumen may be used to guide the lead and to introduce various fluids into the venous system. The second lumen may at various times be used to introduce vasodilation solutions, contrast fluids and adhesives into the venous system.
