Abstract
An improved power-source canister for isolating a power source from the device or devices to be powered when packaged therewith for implantation in a living animal body. The canister is formed by a bottom wall and a continuous side wall and is provided with a cover. Feed-through terminals pass through the side wall, at locations spaced along the perimeter of the side wall, for making an electrical connection between a power source within the canister and the device or devices to be powered. The side wall is formed by four generally straight portions of approximately equal length, each straight portion being generally perpendicular to two of the others and generally parallel to a third. The straight portions are joined by arcuate portions having a radius of curvature approximately equal to one-fourth the distance between parallel straight portions. In a preferred embodiment, the side wall is provided with a flange and the cover is coextensive with the flange such that the cover may be secured to the canister and seal its inner void by means of a heat generating sealing process applied at a point spaced from the canister inner void. The side wall may also include a bevelled portion t…
