Sorin group received a report that the tubing in the suction pump split during a procedure.There was no report of patient injury.None of the tubing was returned to sorin group usa for evaluation.Evaluation of representative tubing from inventory, including a tubing life test, was unable to reproduce the type of failure seen in the returned tubing and found no evidence to suggest a product defect.All samples lasted well beyond the rated lifetime of 6 hours.A review of the dhr was unable to identify any concessions, deviations or non-conformities relevant to the reported failure.The customer stated that the pump head may have been over-occluded during use.The sorin heart-lung instructions for use states "failure to maintain proper occlusion of the roller pump can lead to premature pump head tubing failure." it has been concluded that the reported issue was caused by over-occlusion of the roller pump.No trend for this type of issue has been identified therefore no corrective actions are planned at this time.
