1. An implantable medical device comprising:
- a biocompatible housing comprising at least one fluidically sealing and thermally conductive divider integrally formed therein, said divider configured to divide the inside of said housing into two or more substantially fluidically sealed and thermally conductive compartments;
an electronic assembly for processing sound into stimulation signals mounted in said housing;
a power source mounted in a first of said fluidically sealed and thermally conductive compartments; and
a heat absorption medium, sealed within a second of said fluidically sealed and thermally conductive compartments, thermally coupled to said power source, wherein said divider is configured to allow absorption of heat from said power source through said divider during a state change of said heat absorption medium.
