The first-of-its-kind, the HiRes Ultra 3D Cochlear Implant’s innovative multi-magnet assembly provides alignment to the strong magnetic field of an MRI machine, allowing adult and pediatric users to safely undergo high-resolution imaging, such as 3.0 Tesla MRIs, without any preparation, surgery or head bandaging.
The unique multi-magnet assembly is composed of four rotatable magnets encased in a revolving disc. There is no need for head bandaging or possible surgical removal of the multi-magnet assembly. And there is no need for restriction of head orientation at any time when in an MRI field.
The torque generated in the multi-magnet assembly is so low, that it translates to pressure values below the pain or discomfort thresholds for adults and pediatric recipients.1,2,3,4 The multi-magnet assembly in the HiRes Ultra 3D cochlear implant, when compared to the standard Ultra magnet, has a similar artefact when undergoing an MRI procedure.5
When getting an MRI, all they have to do is take off their processor and headpiece prior to the MRI. And when the scan is done, put them back on to continue hearing. For your patients, this means uninterrupted hearing.
The multi-magnet assembly in the HiRes Ultra 3D cochlear implant was tested to remain functional for life. In bench tests, the multi-magnet assembly keeps going without any risk of demagnetization or damage even after 200 3T MRI routines.6
