Abstract

An apparatus is provided that inhibits movement of a magnetic device relative to a recipient in which the magnetic device is implanted that is caused by exposing the magnetic device to a magnetic field generated externally to the recipient. The apparatus includes a pressure applicator portion configured to apply pressure against the recipient at a location over the magnetic device when the apparatus is pressed against the recipient. The apparatus further includes a support portion configured to support the apparatus against the recipient at a different location than over the magnetic device when the pressure applicator portion applies pressure at the location over the magnetic device. The location and the different location are spaced apart from each other.

First claim

1 . An apparatus for inhibiting movement of a magnetic device relative to a recipient that is caused by exposing the magnetic device to a magnetic field generated externally to the recipient, wherein the magnetic device is implanted in the recipient, the apparatus comprising:
a pressure applicator portion configured to apply pressure against the recipient at a location over the magnetic device when the apparatus is pressed against the recipient; and a support portion configured to support the apparatus against the recipient at a different location than the location over the magnetic device when the pressure applicator portion applies pressure at the location over the magnetic device, wherein the location and the different location are spaced apart from each other.

2 . The apparatus of claim 1 further includes a base portion from which both the pressure applicator portion and the support portion extend.

3 . The apparatus of claim 2 , wherein the base portion includes a surface that extends between, and that is recessed relative to, the pressure applicator portion and the support portion.

4 . The apparatus of claim 1 , wherein the support portion substantially surrounds the pressure applicator portion.

5 . The apparatus of claim 2 , wherein the support portion extends substantially around a perimeter of the base portion.

6 . The apparatus of claim 2 , wherein one or more of the pressure applicator portion, the support portion, and the base portion is/are curved.

7 . The apparatus of claim 1 , wherein the apparatus further comprises a cavity adapted to removably receive a magnetic implant locator.

8 . The apparatus of claim 1 , wherein the pressure applicator portion comprises a mound.

9 . The apparatus of claim 1 , wherein the support portion comprises a flexible material.

10 . A method for inhibiting motion of an implanted magnetic device in a recipient in response to a magnetic field that is generated externally to the recipient, wherein the method comprises:
placing an apparatus on the recipient such that a first portion of the apparatus contacts the recipient at a location that is over the implanted magnetic device, and such that a second portion of the apparatus contacts the recipient at a location adjacent to the implanted magnetic device; and securing the placed apparatus to the recipient such that the first portion and the second portion are pressed against the recipient so as to inhibit movement of the implanted magnetic device while the implanted magnetic device is exposed to the magnetic field.

11 . The method of claim 10 , wherein securing the placed apparatus to the recipient further comprises strapping the apparatus to the recipient.

12 . The method of claim 10 further comprising:
placing a magnetic implant locator in a cavity of the apparatus to assist in aligning the first portion of the apparatus over the implanted magnetic device when placing the apparatus on the recipient.

13 . The method of claim 12 further comprising removing the magnetic implant locator from the cavity after securing the placed apparatus to the recipient.

14 . A device for limiting motion of a magnetic implant in a recipient caused by an externally generated magnetic field, the device comprising:
a first portion that is able to apply pressure on the magnetic implant when the device is secured to the recipient; and a second portion that is able to limit movement of the secured device relative to the recipient during exposure of the magnetic implant to the externally generated magnetic field.

15 . The device of claim 14 further comprising a third portion from which the first portion and the second portion extend.

16 . The device of claim 15 , wherein the third portion comprises a curved surface.

17 . The device of claim 15 , wherein at least one of the first portion, the second portion, and the third portion comprises a flexible material.

18 . The device of claim 14 , wherein the device further comprises a textured surface adapted to inhibit relative movement between the device and a strap that is used to secure the device to the recipient.

19 . The device of claim 18 , wherein the textured surface includes a plurality of spikes.

20 . The device of claim 14 , wherein the second portion comprises one or more bumpers.
