BATTERY ENCASEMENT FOR IMPLANTABLE MEDICAL DEVICES

摘要

The present application describes a battery assembly (100) including a first housing shell (102), a second housing shell (104), an insulator (110) and battery components (130-132). The first housing shell has a first perimeter side wall, a first housing bottom, and a first contact area (113a) on the first housing bottom. The second housing shell has a second perimeter side wall, a second housing bottom, and a second contact area (113b) on the second housing bottom. The second housing shell (104) is disposed/nested in the first housing shell (102) with the second contact area opposing the first contact area. The insulator is interposed between the first housing shell and the second housing shell to effect electrical insulation between the first housing shell and the second housing shell. The battery components include an anode electrode, a cathode electrode, and an electrolyte- containing separator interposed between the cathode electrode and the anode electrode. The battery assembly may further comprise an electronic assembly located in an electronic assembly cavity (116) and is specifically designed for use in implantable medical devices.
