Abstract
A method, including subjecting a subcutaneous medical device containing a first magnet to a magnetic field of an MRI machine, thereby imparting a torque onto the first magnet and resisting the imparted torque via an external device that includes a second magnet, wherein the second magnet is movable relative to another component of the external device
Claims23
A method, comprising:
- subjecting a subcutaneous medical device containing a first magnet to a magnetic field of an MRI machine, thereby imparting a torque onto the first magnet;
- and
- resisting the imparted torque via an external device that includes a second magnet, wherein the second magnet is movable relative to another component of the external device.
A method, comprising:
- placing an Mill compatibility apparatus, including a magnet, against a recipient such that the apparatus at least generally aligns with an implanted magnet in the recipient due to magnetic attraction between the two magnets, wherein the magnet of the apparatus generates a magnetic force that is at least about 2 times as strong as a magnetic force generated by the implanted magnet as measured at a surface of the skin of the recipient closest to the implanted magnet;
- and
- subjecting the recipient and the compatibility apparatus to an Mill field with the two magnets being subjected to the field.
(canceled)
An MRI compatibility assembly, comprising:
- a first component configured to interface with skin of a recipient at a location overlying an implanted magnet of an implantable component;
- and
- a magnet supported by the first component and movable relative to the first component, wherein
- the MM compatibility assembly is configured to be exposed to at least a 1T magnetic field of an MRI machine for at least 15 minutes.
