Livanova (b)(4) received a report that the xtra equipment faulted when the user attempted to empty or fill the bowl during procedure to repair an aorta dissection.Though fluid was being emptied or filled at all times, the sensor always read zero and caused the cell savor to intermittently stop emptying or filling every 10 seconds or so.The user switched the unit out with a back-up unit, which allowed them to process the 3000cc of blood in the bowl.The patient reportedly expired several days after the procedure.
