Patent Images
1. An apparatus, comprising:
- an implantable electronics shell;
electronics disposed in the implantable electronics shell;
an implantable power source shell defining an implantable power source shell interior, the implantable power source shell being hermetically sealed to the implantable electronics shell with a first seal, with the electronics disposed outside the implantable power source shell;
a power source disposed in the implantable power source shell interior, the power source being sealed in the implantable power source shell with a second seal, the power source comprising;
an annular anode connected to a first terminal; and
a cathode connected to a second terminal and disposed around the anode,wherein the anode and the cathode are arranged in a bobbin configuration,wherein an exterior of the apparatus includes an exterior of the implantable electronics shell and an exterior of the implantable power source shell.

Abstract
One example includes a battery that includes a stack of at least one substantially planar anode and at least one substantially planar cathode, wherein the stack defines a contoured exterior, and a battery housing enclosing the stack, the battery housing defining a battery housing exterior, wherein the contoured exterior of the stack is shaped to conform to a contoured interior of the battery housing that approximately conforms to the battery housing exterior, the battery produced by the process of modeling, using fluid dynamics, an exterior of a biocompatible housing and shaping the battery housing to conform to at least some of the exterior of the biocompatible housing.
