Abstract
An active medical implant has a hermetically sealable capsule formed by a first part and a second capsule-closing part, whereby the capsule is arranged to hold a battery unit and an electronics unit, conductors for electrically connecting the battery to the electronics unit and contacts with associated conductors arranged on the exterior of the capsule for connection to electrodes. The first part and the second part are made of an essentially biocompatible material, and a partition wall is arranged to form a first essentially closed space in the first part for the battery unit, and an electrically insulating layer, impermeable to battery chemicals, is arranged on the surfaces of the biocompatible material facing the first closed space. An additional space is formed for the electronics between the capsule-closing part and the partition wall.
