Abstract
An improved system and method for placing implantable medical devices (IMDs) such as leads within the coronary sinus and branch veins is disclosed. In one embodiment, a slittable delivery sheath and a method of using the sheath are provided. The sheath includes a slittable hub, and a substantially straight body defining an inner lumen. The body comprises a shaft section and a distal section that is distal to, and softer than, the shaft section. A slittable braid extends adjacent to at least a portion of one of the shaft section and the distal section. In one embodiment of the invention, the sheath further includes a transition section that is distal to the shaft section, and proximal to the distal section. The transition section is softer than the shaft section, but stiffer than the distal section.
