Abstract: The invention relates to an implantable pulse generator (100), IPG, for stimulation of a neurological cellular mass comprising a casing (2) that at least partially encloses the pulse generating module (PGM) (4) and that is transparent to radio-frequency electromagnetic fields, or wherein the pulse generating module (4) includes a controller circuit (18) provided as two or more circuit boards (20, 22), co-operatively connected, one such circuit board being an interface circuit board, where at least one component of the controller circuit (8) is located on the interface circuit board (20), and feed through wires for connector block (6) are connected thereto (20), and one of the opposing surfaces of the interface circuit board (20) is aligned over apertures (48, 50, 52) in the PGM housing for the feed through wires.

Abstract: A combined set including a vibration actuator and an implantable device provided to be implanted in an inner ear part is disclosed. The implantable device has a surface in contact with an inner ear fluid when inserted in said inner ear part. The implantable device includes a frame having an inner wall and a slidably movable member having an outer wall which is connected to the vibration actuator. The slidably movable member is provided for transferring energy supplied by the vibration actuator from and towards the inner ear fluid by means of a translational movement. The slidably movable member is at least partially mounted inside the frame in such a manner that a gap extending between the inner wall of the frame and the outer wall of the member is less than or equal to 0.1 mm.
