Abstract
Abstract An implantable medical device has a novel ceramic enclosure with joinable multi-layered clamshells. In the preferred embodiment one half of the enclosure carries the hybrid circuitry and feedthroughs of, for example, a pacemaker, while, the other half carries a battery. The advantages over the prior art include higher transparency to radio frequency waves (for telemetry purposes), and reduced costs and construction time.
