Abstract

Implantable components configured to be secured to a recipient with a bonding agent are presented herein. The implantable components are configured to be implanted adjacent to a recipient's bone and/or tissue and have a surface for attachment to the bonding agent.

Claims (27)

1. 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.

2. The bone conduction device of claim 1 , wherein the surface features comprise pores in the first surface having an irregular shape so as to cause the bonding agent to undergo one or more turns when the bonding agent fills the pores.

3. The bone conduction device of claim 2 , wherein the pores having irregular shapes are chemically etched pores.

4. The bone conduction device of claim 1 , wherein the surface features comprise a plurality of elongate grooves each having an undercut region.

5. The bone conduction device of claim 4 , wherein the plurality of elongate grooves comprise a plurality of L-shaped grooves.

6. The bone conduction device of claim 1 , wherein the housing has a shape configured to distribute pressure resulting from the magnetic coupling and the vibration received from the external actuator.

7. The bone conduction device of claim 6 , wherein the housing has a generally flattened-elliptical cross-sectional shape.

8. The bone conduction device of claim 6 , wherein the housing has a generally semi-circular cross-sectional shape.

9. The bone conduction device of claim 6 , wherein the housing has a generally hexagonal cross-sectional shape.

10. The bone conduction device of claim 6 , wherein the housing has a generally rounded-cylindrical cross-sectional shape.

11. The bone conduction device of claim 1 , wherein the implantable anchor comprises a plurality of implantable anchors each comprising:

a housing having a first surface configured to be secured to the bone with a bonding agent, wherein the first surface of each housing 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 surfaces of each housing, and

an implantable magnet enclosed in the housing configured to be magnetically coupled to the external magnet.

12. The bone conduction device of claim 11 , wherein the plurality of implantable anchors are disposed on a support structure.

13. The bone conduction device of claim 12 , wherein the support structure has a support surface comprising 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 support surface.

14. The bone conduction device of claim 12 , wherein the support structure is a mesh.

15. The bone conduction device of claim 14 , wherein the mesh is flexible.

16. The bone conduction device of claim 14 , wherein the mesh is configured to osseointegrate with the bone.

17. The bone conduction device of claim 11 , wherein the plurality of implantable anchors comprises two or more groups of implantable anchors configured to be secured to the bone at different locations.
