US 2003/0204231 A1 · Method and apparatus for placing a coronary sinus/cardiac vein pacing and defibrillation lead with adjustable electrode spacing

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.
