  1. IMPLANTED DEVICES. Wreford-Brown CE., Bodwin DM Virginia Mason Center for Hyperbaric Medicine, Seattle, WA 98101. I BACKGROUND Early pacemakers had captive air and did not tolerate compression due to carcass deflection. Recent devices are designed for better pressure tolerance. II METHODS Device manufactures were contacted for testing data. Data was pulled from manufacturers through phone calls, online posted data, and email. III RESULTS Automatic Implanted Cardiac Defibrillators and Pacemakers. Implanted Insulin Infusion Pumps. IPX 8 and Animus pumps are rated for swimming only, with 12 ft maximum depth Mini med pumps are not water proof or pressure tested for hyperbaric therapy Boston Scientific pacemaker to 2.35 ATA ELA Medical pacemaker to 4 ATA St. Jude/Ventritex pacemaker to 7 ATA St. Jude/Ventritex ICD to 3 ATA Medtronic pacemaker and ICD to 2.5 ATA Biotronic pacemaker and ICD to 3 ATA Cochlear Implants. ITB TherapySM (Intrathecal Baclofen Therapy) Nucleus C124R and CI124M to 2.5 ATA Freedom to 4 ATA Medtronic Synchro Med II to 2 ATA IV CONCLUSIONS Manufacturers are designing some implantable devices that are compatible with our current routine hyperbaric treatment protocols. Testing methods vary among manufacturers and among devices within the same manufacturer. Standardized testing and design would increase the safety of hyperbaric patients with implantable devices.
