The following fields were updated due to additional information: d10: device available for eval yes, d10: returned to manufacturer on: 10/06/2020 investigation conclusion it was reported that a product failure with item 10031776 may have resulted in a patient death.Received one used extension set model 10031776 lot 20065112.Also received fifty new extension sets model 10031776 lot 20065112.The set was visually inspected for kinks, incomplete bonding engagements, holes/tears in the tubing or damages to the components.Visual inspection found a lateral crack in the event sample¿s female luer wall (p/n 630-01363) located at the top end of the female luer opposite of the luer gate.The location of the luer gate on the female luer (below the ¿wings¿) indicates that this female luer was manufactured after the change order where the injection gate was moved to a lower location to help mitigate and prevent female luer cracks.No signs of visible over torque marks were observed on the female luer.No other damages or anomalies were observed with the set or the components during initial visual inspection.Visual inspection of the fifty associated sets as received did not observe any damages or cracks with any of the components.Functional testing was performed by attaching a 10ml lab syringe filled with bleach water to the event set¿s female luer.The syringe plunger was gently depressed and a leak was observed where the noted crack was found.The syringe was disconnected from the set and the set was pressure tested using air pressure (pounds per square inch or psi, unit of pressure) while submerged underwater (per dir # 10000360033 ¿ iv disposable leak test method).The air supply regulator was set to a pre-pressure level of 5psi +/- 1 psi, ensuring air is flowing.The set was attached to the output of the air pressure regulator with a closed lab stopcock at the end of the set and air bubbles were observed leaking from the previously noted female luer damage at 5psi.A leak is defined as one air bubble approximately every 5 seconds.No other leaks or issues were observed.Bd supplier quality engineering manufacturing was notified of the component failure and a quality systems supplier notification memo was issued to the filter supplier (borla).15 of the 50 associated sets including the event sample were sent to bd global materials coe lab for further analysis to determine the possibility of material deficiency (gml-20-10-006).The analysis was performed using optical microscopy, sem images, ftir, and differential scanning calorimetry (dsc) to identify or eliminate possible root causes of the cracked female luer.The customer¿s report of a product failure was confirmed due to lateral cracks found in the event model 10031776¿s female luer.The root cause of the female luer cracks were not definitively determined.The proximate cause of female luer cracks were identified to be a result of an excess application of external force applied between mating components.See h10.
