MECHANICAL FIXATION SYSTEM FOR A PROSTHETIC DEVICE
First Claim
1. A fixation system for a bone conduction device comprising:
- a bone anchor configured to be implanted in a recipient of the bone conduction device;
an abutment coupled to the bone anchor defining a conduction path to the bone anchor such that vibrations applied to the abutment are transferred to the bone anchor, the abutment comprising a plurality of inter-locking stacked plates disposed adjacent the bone anchor forming part of the conduction path; and
a vibratory coupler extending from the bone conduction device, comprising a second conduction surface and a magnet, wherein the magnet attracts to the abutment so as to couple the second conduction surface to the abutment, thereby enabling vibrations to pass through the conduction path,wherein the plates are configured to laterally slide with respect to another in response to tangential forces incident upon the abutment.

Abstract
A fixation system for a bone conduction device is disclosed. An abutment is coupled to a bone anchor such that vibrations applied to the abutment pass into the bone anchor. The abutment defines a conduction path to the bone anchor such that vibrations applied to the abutment are transferred to the bone anchor. The abutment comprises a plurality of interlocking stacked plates disposed adjacent the bone anchor, wherein the plates form part of the conduction path. The fixation system also comprises a vibratory coupler extending from the bone conduction device, comprising a second conduction surface and a magnet, wherein the magnet attracts to the abutment so as to couple the second conduction surface to the abutment, thereby enabling vibrations to pass through the conduction path. The plates are configured to slide laterally in response to tangential forces incident upon the abutment.

14. An implantable anchor for coupling a vibratory coupler extending from the bone conduction device to a recipient, the bone conduction device comprising a second conduction surface and a magnet, the anchor comprising:
-
a bone anchor configured to be implanted in the recipient of the bone conduction device; and an abutment coupled to the bone anchor defining a conduction path to the bone anchor such that vibrations applied to the abutment are transferred to the bone anchor, the abutment comprising a plurality of inter-locking stacked plates disposed adjacent the bone anchor forming part of the conduction path; wherein when the second conduction surface is adjacent the abutment the magnet attracts to the abutment so as to couple the second conduction surface to the abutment, thereby enabling vibrations to pass through the conduction path, and wherein the plates are configured to laterally slide with respect to another in response to tangential forces incident upon the abutment. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
