Implantable medical device battery
First Claim
1. An implantable medical device comprising:
- a battery including;
a tubular battery housing, wherein an external surface of the tubular battery housing comprises a biocompatible material,a battery header secured to an open end of the tubular battery housing, wherein the tubular battery housing and the battery header combine to form a substantially sealed enclosure,one or more voltaic cells within the substantially sealed enclosure, anda feedthrough electrically connected to the voltaic cells and extending through the battery header to form a battery terminal;
an electronic component subassembly including;
an electronics tray secured to the battery header opposite the tubular battery housing, anda set of electronic components coupled to the electronics tray and electrically connected to the battery terminal; and
a tubular cover secured to the battery header opposite to the tubular battery housing, wherein the battery header and the tubular cover combine to form an enclosure encasing the feedthrough and the electronic component subassembly,wherein the battery header includes a radial groove opposite the tubular battery housing, wherein the electronics tray includes a radial protrusion, andwherein the electronics tray is snap-fit to the battery header in that the radial protrusion of the electronics tray is mated to the radial groove of the battery header.

Abstract
A battery comprises a tubular housing. An external surface of the tubular housing comprises a biocompatible material. The battery further comprises a battery header secured to an open end of the tubular housing, and the tubular housing and the battery header combine to form a substantially sealed enclosure. The battery also comprises one or more voltaic cells within the substantially sealed enclosure, and a feedthrough electrically connected to the voltaic cells and extending through the battery header to form a battery terminal. The battery header includes a radial groove opposite the tubular housing, and the radial groove is configured to receive a mating snap-fit electronic component subassembly of an implantable medical device.
