An exciting new device, which utilizes an Omron MEMS (Micro Electromechanical Systems) mass flow sensor, is entering the medical field and will allow people who would normally be hospitalized while awaiting a heart transplant, to be discharged and live at home while waiting for their new heart. The SynCardia temporary Total Artificial Heart is a bridge-to-transplant total heart replacement for patients who have end-stage heart failure of both ventricles (biventricular failure). The device is implanted, and connected to a driver unit outside the body that powers the Total Artificial Heart and contains all of the pumps, motors and associated electronics. The Total Artificial Heart began sustaining patients in the hospital in the early 1980s. Recent innovations and miniaturization of the driver design resulted in the new 13.5 lb Freedom® portable driver, designed to provide patients with more “freedom” in their daily lives. This driver is CE approved in Europe and is currently in an FDA-approved Investigational Device Exemption (IDE) clinical study in the U.S. The Freedom driver uses the very compact D6F-03A3-000 MEMS flow sensor, from Omron Electronic Components LLC. This fast-response, ultra-compact and lightweight sensor contributed greatly to making the Freedom driver small and light enough to be carried by the patient in a backpack.
