Abstract
An active medical implant has a hermetically sealable capsule formed by a first part and a second closing part, the capsule being devised to hold a battery unit, an electronics unit, conductors for electrically connecting the battery to the electronics unit, and contacts arranged on the exterior of the capsule for connection to electrodes. The first part is made, at least in part, of a rolled, multi-layer composite sheet or plate, one layer of which is made of a biocompatible material and a second layer of which is made of a diffusion-proof material which is essentially resistant to corrosive chemicals. The two layers are joined by rolling, with the layer made of biocompatible material constituting the outer wall of the capsule. The closing part contains a layer of the biocompatible material serving as the capsule's outer wall and a partition wall made of diffusion-proof material which is essentially resistant to corrosive chemicals, is arranged to form a first essentially closed space for the power source in the first part. A second space for the electronics unit is formed between the wall closing the capsule and the partition wall.
