A transvenous bipolar lead (1) specifically designed for coronary sinus implantation. The lead has essentially two main characteristics, the distal end has a 45-degree pre-shape to facilitate introduction of the lead through a catheter and provide optimal positioning of the lead (1) within the coronary sinus. The lead further features a distal electrode tip (20) which itself is canted at an angle of 45 degrees on the distal end of the lead to provide a very close contact with the coronary sinus upper wall and, thus, with the left atrium inferolateral wall. In addition, each of these sections (51, 53) is flexible to permit the lead to be introduced through a relatively small-sized guide-catheter. Finally, the lead further features a center lumen to also permit the lead to be straightened for introduction with a stylet.
