Medical electrical lead
First Claim
1. A medical electrical lead comprising:
- a connector assembly;
a lead body coupled to the connector assembly, the lead body having a first distal section and a second proximal section, the first section having a flexible first bend and a first stiffness, the second section having a flexible second bend and a second stiffness, the first stiffness greater than the second stiffness, second bend is between 15 to 90 degrees, the first bend is between 15 to 90 degrees; and
a tip electrode coupled to the lead body.

Abstract
A transvenous bipolar lead 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 within the coronary sinus. The lead further features a distal electrode tip 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 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.
