Claim 7:
8. A bone conduction hearing prosthesis anchoring fixture, comprising:
a main body including a threaded section configured to be implanted into a skull bone, and
a proximal portion, the proximal portion being located above the main body when the anchoring fixture is implanted into the skull bone, wherein
the bone conduction hearing prosthesis anchoring fixture is configured for anchoring a bone conduction hearing prosthesis component to the skull bone at a location behind an external ear so that sound is transmitted from the bone conduction hearing prosthesis component via the skull bone to a cochlea, and
a portion of the bone conduction hearing prosthesis anchoring fixture main body between a proximal end at the proximal portion and a distal end opposite the proximal end of the bone conduction hearing prosthesis anchoring fixture has a wide diameter portion configured to impart a compressive action that is concentrated to a hard cortical part of skull bone tissue when the bone conduction hearing prosthesis anchoring fixture is fully seated in the skull bone, wherein
the wide diameter portion is configured to exert the compressive action onto the skull bone in a radial direction.
