Methods And Apparatuses For Inhibiting Movement Of Implanted Magnetic Devices
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.
