Claim Text:
1. A power source for an implantable medical device, the power source comprising: a plurality of planar solid state batteries overlaying one another in an aligned arrangement and adhered to one another to form a stack, the stack having first and second edges extending along a height of the stack, the first and second edges being opposite one another; a first group of conductive vias, each via of the first group extending through a positive contact of a corresponding battery and approximately parallel to the first edge of the stack; a second group of conductive vias, each via of the second group extending through a negative contact of a corresponding battery and approximately parallel to the first edge of the stack; a first group of redistribution layers, each redistribution layer of the first group of redistribution layers extending over a first surface of a corresponding battery and each including a first conductive trace, coupled to the positive battery contact of the corresponding battery, and a second conductive trace, coupled to the negative contact of the corresponding battery, each first conductive trace extending to the first edge of the stack, and each second conductive trace extending to the second edge of the stack; and a second group of redistribution layers, each redistribution layer of the second group of redistribution layers extending over a second surface of a corresponding battery, the second surface opposite the first surface, and each second group of redistribution layers including a conductive bonding runner, each conductive bonding runner being coupled to a corresponding via of the first and second groups of conductive vias and to a corresponding conductive trace of an adjacent and confronting redistribution layer of the first group of redistribution layers.
