1. A medical electrical lead, comprising:
- a first lead having a first electrode coupled adjacent a distal end portion thereof, said distal end portion of said first lead being anchorable in the coronary sinus of a patient; and
a second lead coupled with and moveable along said first lead, said second lead having a second electrode located thereon wherein the position of the first and second electrodes may be varied relative to one another by movement of said second lead along said first lead.

Abstract
A medical electrical lead, which may be useful in coupling an implantable medical device, is comprised of a first and second lead. The first lead has a first electrode coupled adjacent a distal end portion thereof. The distal end portion of the first lead is anchorable in the coronary sinus of a patient. The second lead is coupled with and moveable along the first lead. The second lead has a second electrode located thereon wherein the position of the first and second electrodes may be varied relative to one another by movement of the second lead along the first lead. A rubber tip holds the relative position of each electrode.

16. A method for positioning a medical electrical lead in a coronary sinus, comprising:
-
inserting a first lead within the coronary sinus wherein the first lead includes a first electrode;
anchoring the first lead within the coronary sinus;
guiding an over-the-wire lead into the coronary sinus wherein the over-the-wire lead includes a second electrode and the first lead acts as a guide for the over-the-wire lead; and
adjusting the relative position of the second electrode relative to the first electrode by controlling the position of the over-the-wire lead relative to the first lead. - View Dependent Claims (17)
