Abstract
An implantable medical device having opposed major sidewalls of contoured shape closely fits the curved shape of a body. The contoured major sidewalls can have a curved shape of a continuous radius with the major sidewalls deflecting in a similar direction. Alternatively, the major sidewalls can have a curved shape corresponding to more than one radius. The device housing is either deep drawn or includes two clam shells that are secured together.
