We have a patient that is a candidate for HBOT (Radiation Proctitis).  He has bi-lateral cochlear implants.  The manufacturer is AB Bionics, I called them to ask if what is implanted beneath the skin is safe for therapy, their answer was basically, "they cannot say if it is safe or not and not sure if they can handle the pressure and to check with the surgeon who implanted them."  Now we checked on another manufacturer, "Cochlear Americas" and their products are safe up to 120ft of seawater.  Has anyone treated a patient with cochlear implants from AB Bionics?
