1. An implantable medical device, comprising:
- (A) a substantially hermetic container, comprising;
(1) a lid having a circumferential lid edge surface;
(2) a shield having a bottom wall and a circumferential side wall connected to said bottom wall and terminating at an outer circumferential flange surface overlapping and sealingly attached to said circumferential lid edge surface to provide said container;
(B) an electronic circuit located within said container;
(C) a feedthrough extending through said shield and coupled to said electronic circuit;
(D) a shroud of a resilient, compliant plastic having a connector bore means for receiving a connector of an electrical lead formed therein and enclosing said circumferential lid edge surface, said flange surface and said feedthrough; and
(E) an electrical connector means for coupling to an electrical lead, mounted in said material of said shroud, coupled to said feedthrough and exposed to said connector bore means.

Abstract
An enclosure for use in pacemaker as well as other implantable medical devices has a substantially planar lid which is welded to a circumferential flange formed on a deep drawn shield. The shield and lid form a "container" which is encased in a compliant shroud which isolates the welded flange from direct body contact and which enhances the biocompatibility of the entire device. A resilient and compliant shroud material accepts connector module components, integrates seals, provides storage for lead wrap, and provides a simple low cost and reliable method of attaching stimulating leads or other structures required by the medical device.
