| 1. A pacing lead and catheter assembly for accessing lateral branch veins of the coronary sinus, the pacing lead and catheter
assembly comprising:
a guide catheter having an open lumen extending therethrough, a proximal end and a distal end, said distal end pre-formed
with a guide curve; and
a chronic pacing lead having an elongated lead body, an electrode coupled to the lead body and in communication with a conductor,
and a fixation mechanism coupled to the lead body, wherein the pacing lead is slidably receivable within the guide catheter
lumen, and has a proximal end and a distal end pre-formed with a first curve and a second curve extending proximally from
the first curve, said second curve adapted to mate with the guide curve to direct the first curve into a selected branch vein
of the coronary sinus;
wherein the lead body is non-torquable such that, during implantation, rotation of the proximal end is not transferred to
the guide curve.
