1. A lead comprising:
- a lead body adapted to carry signals to and from a heart, the lead body having a proximal portion and a distal portion;
a connector located at a proximal end of the lead, the lead adapted for connection to a signal generator for monitoring or stimulating cardiac activity, the lead constructed and arranged for implantation within a coronary vein, a portion of the distal portion of the lead body having a preformed radius of curvature substantially the same as or slightly smaller than a coronary sinus and geometrically shaped to hug a wall of the coronary sinus upon implantation therein; and
at least one electrode coupled with the lead body.

Abstract
A lead for monitoring or stimulating cardiac activity is provided. The lead is adapted for implantation on or about the heart within the coronary vasculature and for connection to a signal generator. The lead body has one or more electrodes associated therewith. The lead is constructed and arranged so that when it is implanted, the electrodes are housed in the coronary vasculature and urged into intimate contact a vessel wall.

15. A lead comprising:
-
a lead body adapted to carry signals to and from a heart, the lead body having a proximal portion and a distal portion, and an intermediate portion therebetween;
a connector located at a proximal end of the lead;
the distal portion of the lead body constructed to be implanted within a coronary vein;

21. A method comprising:
-
providing a coronary sinus lead comprising;
a lead body adapted to carry signals to and from a heart, the lead body having a proximal portion and a distal portion;
a connector located at a proximal end of the lead, the lead adapted for connection to a signal generator for monitoring or stimulating cardiac activity, the lead constructed and arranged for implantation within a coronary sinus, the distal portion of the lead body having the same radius of curvature as or smaller radius of curvature than the coronary sinus and geometrically shaped to hug a wall of the coronary sinus upon implantation therein;
a first electrode associated with the distal portion of the lead body, the first electrode including a first electrode contact area;
a second electrode associated with the distal portion of the lead body, the second electrode including a second electrode contact area, the distal portion of the lead constructed and arranged to urge the first and second electrodes toward a wall of the coronary sinus;
inserting the coronary vein lead into the coronary sinus, disposing the first and second electrodes in the coronary sinus;
advancing the distal portion of the lead through the coronary sinus; and
sensing and pacing of the heart via the coronary vein lead in its implanted site in a coronary vein. - View Dependent Claims (22, 23)
