Event Description

Medtronic received information that during use of an affinity pixie oxygenator, it was reported by a researcher that the oxygenators used in their research projects had mechanical failures when used within inline perfusion systems for pig liver and pig kidney.The flow rates were below 300 mmhg and between 30-60 minutes after beginning the process, the device would form a crack and cause outward leaking.The devices were replaced to complete the procedures.There were no adverse patient effects associated with this event.Medtronic received additional information that the customer is part of a research group working on pig and human liver perfusions.The breakage of all the devices were noticed within the same week of experiments, but the exact dates are not available.The customer stated that no blood was used but the solution used did leak significantly throughout the perfusion.The customer stated that the defect was not visible, only through the leakage.
