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.
Claims20
An apparatus, comprising:
- an implantable device housing;
- electronics disposed in the implantable device housing;
- a battery disposed in the implantable device housing, the battery comprising;
- a battery housing;
- 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 the implantable device housing defines an implantable housing interior shaped to conform to an implantable housing exterior having modeled fluid dynamics, and the battery housing defines a contoured interior and a battery housing exterior, wherein the anode and cathode are shaped to conform to the contoured interior of the battery housing and the battery housing exterior is shaped to conform to the implantable housing interior.
A method for construction of an implantable device battery, the method comprising:
- shaping an implantable device housing by modeling fluid dynamics of the implantable device housing, including defining an implantable device housing exterior having modeled fluid dynamics, and also including defining an implantable device housing interior conforming to the implantable device housing exterior;
- shaping a battery housing including defining a battery housing exterior conforming to the implantable device housing interior, and also including defining a battery interior conforming to the battery housing exterior;
- forming an anode of the implantable device battery, the anode adapted to be connected to a first terminal of the implantable device battery, the anode shaped to conform to the battery housing interior;
- forming a cathode of the implantable device battery, the cathode adapted to be connected to a second terminal of the implantable device battery of the implantable device battery, the cathode formed of a compressed material pressed into the battery housing to conform to the battery housing interior;
- and
- arranging the anode and the cathode in a bobbin configuration.
A method for construction an implantable device, comprising:
- shaping an exterior of a housing of the implantable device, including modeling fluid dynamics of the exterior wherein shaping includes shaping an interior of the housing to conform to the exterior of the housing;
- shaping an interior of the housing to conform to the exterior of the housing;
- shaping an exterior of a battery housing to fit the interior of the housing;
- shaping an interior of the battery housing to conform to the exterior of the battery housing;
- stacking at least one anode with at least one cathode into a stack;
- and
- disposing the stack into the battery housing.
