Patent ID: 8172760

Claim:
An implantable medical system comprising: a first die substrate with a first outer surface; a second die substrate with a second outer surface; and a medical device with a first portion that is mounted to the first die substrate and a second portion that is mounted to the second die substrate, wherein the first portion comprises at least one first conductive element terminating at a mating surface and the second portion comprises at least one second conductive element terminating at a mating surface, the first and second die substrates being fixed to each other and substantially hermetically sealed to each other, the medical device substantially encapsulated between the first and second die substrates, the at least one first conductive element of the first portion being electrically connected to the at least one second conductive element of the second portion when the first and second die substrates substantially hermetically seal and substantially encapsulate the medical device, the first and second outer surfaces of the first and second die substrates being directly exposed to a biological material.
