Abstract
The invention is directed to medical leads for use with implantable medical devices. Various features of medical leads are described, many of which may be useful in a variety of different leads, e.g., used in a variety of different applications. In one embodiment, the invention provides a medical lead of varying stiffness characteristics. In another embodiment, the invention provides a medical lead having a semi-conical shaped distal tip that becomes wider at more distal tip locations. In either case, described lead features may be particularly useful for J-shaped lead configurations used for implantation in a patient's right atrium. Many other types of leads, however, could also benefit from various aspects of the invention.
