The following were reviewed as part of this investigation: patient severity, frequency analysis, applicable previous investigation(s), sample (if available), applicable fmea documents, labeling, and applicable manufacture records.Based on a review of this information, the following was concluded: the complaint of a leak is confirmed but the exact cause remains unknown.Two ez huber infusion sets were returned for investigation.One sample was returned in sealed packaging.The second sample was returned without the packaging and the safety mechanism engaged.Usage residue was observed.The used sample was flushed with water using a 12 ml syringe and water was observed to leak at the y-site connector.Microscopic observation of the leak location revealed a longitudinal crack starting at the proximal end of the y site connector.The crack extends down to the y site extension leg stem section of the hub.Material whitening is observed surrounding the crack surfaces indicating that an outward radiating force was applied from within the connector.The crack was likely initiated by the advancement of a tapered object into the hub; however, the exact conditions the hub was exposed prior to or after packaging are unknown.The sealed sample was opened and no apparent issues were observed.It was then flushed and was found to be patent to infusion.Since the leak in the hub was found to be caused by a crack in the connector, the complaint is confirmed.A lot history review (lhr) of recv2131 showed no other similar product complaint(s) from this lot number.
