Abstract: A system (102) comprising a box (104) for implanting in a mamMal body part (106), which box is provided with a first electrical contact (110, 121, 114, 116, 118, 120), and a module (108) for accommodating in the box, which module is provided with a second electrical contact (122, 124, 126) for cooperation with said first electrical contact. The first electrical contact and the second electrical contact are mutually movable, at least in a stationary accommodation of the module in the box, between a contact position in which said first and second electrical contacts are electrically connected, and a non-contact position in which said first and second electrical contacts are separated from each other.

Abstract: The invention relates to an implantable connection device (100) comprising a porous carrier (120) to which bone tissue (1) can attach and an electrical device that is embedded in the carrier or at least space for such a device. The carrier may particularly comprise ceramic particles, for example a mixture of hydroxyapatite and tricalcium phosphate. The electrical device may consist of one or more feedthrough wires to which leads (11, 21) of external devices can be coupled on both sides of the connection device. The connection device can for example be implemented into the skull (1) of a patient to provide an electrical connection between electrodes in the brain and an external pulse generator.
