23. A process for producing an implantable, hermetically sealed housing for components of an implantable medical device, wherein said housing comprises an hermetically tight separation wall which divides said housing into a first chamber for housing a storage for electrical energy for supplying electric current to the medical device and a second chamber for housing said electronic unit, the process comprising:
-
machining two chamber-like depressions from two opposing sides into a blank, wherein the remaining material between said two depressions constitutes said hermetically tight separation wall; and
forming a first and a second chamber by placing an hermetically tight cap onto each of the two depressions.

24. A process for producing an implantable, hermetically sealed housing for components of an implantable medical device, wherein said housing comprises an hermetically tight separation wall which divides the housing into a first chamber for housing a storage for electrical energy for supplying electric current to the medical device and a second chamber for housing said electronic unit, the process comprising:
-
forming, in the course of a first deep-draw step, a first open hollow space in a flat blank;
forming, in the course of a second deep-draw step which is conducted from a side of the blank that is opposite to that from which the first deep-draw step has been conducted, a second open hollow space in a bottom of the first open hollow space; and
forming a first and a second chamber by placing an hermetically tight cap onto the openings of each of the two hollow spaces.

25. A process for producing an implantable, hermetically sealed housing for components of an implantable medical device, wherein said housing comprises an hermetically tight separation wall which divides the housing into a first chamber for housing a storage for electrical energy for supplying electric current to the medical device and a second chamber for housing said electronic unit, the process comprising:
-
forming, in the course of a deep-draw step, a first open hollow space in a flat blank, said first open hollow space having a bottom; and
placing a hollow body which is open on one side with its open side onto said bottom, and connecting the hollow body with the bottom in an hermetically tight manner, thus forming a first and a second chamber.

27. A process for producing an implantable, hermetically sealed housing which houses components of an implantable medical device, wherein said housing comprises an hermetically tight separation wall which divides the housing into a first chamber for housing a storage for electrical energy for supplying electric current to the medical device and a second chamber for housing said electronic unit, the process comprising:
-
forming, in the course of a deep-draw step, a first open hollow space in a flat blank, said first open hollow space having a bottom;
placing a hollow body which is open at both ends one of its open ends onto said bottom, and connecting the hollow body with the bottom in a hermetically tight manner, thus forming a first chamber; and
placing an hermetically tight cap onto the second open end of the hollow body thus forming a second chamber.
