Terumo Cardiovascular, a medical device manufacturer, has informed hospitals that they will no longer allow in-house repair technicians to maintain or fix their Advanced Perfusion System 1 Heart Lung Machine. This change, requiring hospitals to enter into repair contracts with the manufacturer, will increase medical costs and potentially lead to delays in patient care. Medical device manufacturers have been lobbying against right-to-repair legislation, claiming patient safety concerns, despite the expertise of hospital technicians.
