Patent ID: 8790409

Claim:
A bone conduction device, comprising: an external component comprising: a sound input element configured to convert received sound into electrical signals, a sound processor configured to utilize the electrical signals to generate control signals, an actuator configured to generate mechanical vibration in response to the control signals received from the sound processor, and an external magnet mechanically coupled to the actuator; and an implantable anchor configured to be implanted adjacent to bone comprising: a housing having a first surface configured to be secured to the bone with a bonding agent, wherein the first surface comprises one or more surface features having a shape such that the bonding agent is configured to undergo one or more turns when the bonding agent fills a plurality of the surface features so as to create an interlock between the bonding agent and the first surface, and an implantable magnet enclosed in the housing configured to be magnetically coupled to the external magnet.
