Abstract:
An implantable medical device having opposed major sidewalls of contoured shape closely fits the curved shape of a body. The contoured major sidewalls can have a curved shape of a continuous radius with the major sidewalls deflecting in a similar direction. Alternatively, the major sidewalls can have a curved shape corresponding to more than one radius. The device housing is either deep drawn or includes two clam shells that are secured together.
Abstract:
The present invention provides an electrochemical cell of either a primary or a secondary chemistry housed in a casing having opposed major side walls of a contoured shape.
Abstract:
An economical method for manufacturing an electrode assembly of virtually any shape to fit into a similarly shaped casing without compromising volumetric efficiency is described. This is accomplished by providing an electrode assembly of multiplate anode and cathode plates that substantially match the internal shape of the casing. That way, no matter what shape the device being powered by the cell dictates the electrode assembly assumes, as little internal volume as possible is left unoccupied by electrode active materials.
