Abstract
The present invention is a low profile hermetic package for an implantable medical device. The package includes a non-conductive substrate including a plurality of straight conductive vias through the non-conductive substrate. A conductive cover hermetically enclosing an electronics circuit is bonded to the non-conductive substrate. The device is low profile. The width of the non-conductive substrate is grater than the height of the cover.
