Manufacturer Narrative

Livanova received a report stating that the tubing had disconnected from the inlet connector of another manufacturer oxygenator.The issue occurred about three minutes after the initiation of support.No patient affected.It was reported that the circuit was dry assembled and connections were double tie banded using a tie gun.Therefore, the connection between livanova tubing and the oxygenator was made by the customer.A review of the dhr did not identify any deviations, non-conformity or material scrap/requests relevant to the reported issue.The oxygenator and the disconnected tubing were returned to livanova for investigation.Visual inspection could not identify any connection issues between the tubing and the oxygenator.Moreover, wall thickness and id of the tubing was found to be within specification.Similar complaints have been registered in the last 12 months on different customers/pts codes.Based on all the gathered information, the most likely root cause of the reported tubing disconnection can be traced back to an alteration of the chemical / mechanical characteristics of the tubings (which are supplied by a livanova).However, this could be enhanced by the tubing not being properly secured to the oxygenator inlet.Supplier of the tubing has been formally notified of the issue.At the moment, no other corrective action is deemed necessary.Livanova will keep monitoring the market.
