A medical implant includes a hermetically sealed hollow housing having a hermetically sealed feedthrough suitable for conducting electrical signals to and from the hollow housing without impairing the hermetic seal thereof. The hollow housing includes a circuit suitable for measuring signals from the human body, sending signals to the human body, and transmitting signals to a receiver located outside the body. The implant also includes a connection housing having an insulating connection body, an externally accessible cavity for connecting an implantable electrode line, an insulating substrate having at least one electrically conductive strip conductor structure, and contacts that are securely electrically connected to a strip conductor structure present in or on the substrate material. The substrate may be embedded in the connection body in such a way that the contacts are present in the externally accessible cavity.
