Device manufacture date: 08/08/2015-08/21/2015.Device evaluation: results: one used sample was returned for evaluation.A visual inspection revealed the tip shield was not activated and was connected to the catheter adapter.The v-clip in the tip shield was tilted.As part of a simulated use test, the v-clip was lightly touched to reset it and the safety mechanism was then successfully activated.A review of the device history record revealed no irregularities during the manufacture of the reported lot # 5299015.A manufacturing review revealed no abnormalities in the incoming material, assembly process, or packaging process.Conclusion: although the customer's indicated failure mode was observed, an absolute root cause for this incident cannot be determined.Our quality engineer notes that a probable cause for this incident is tilted v-clips causing the tip shield to stick and not activate.Employees will be trained not to squeeze transfer boxes in the production process, v-clip assembly operators will be notified to not touch tip shields, and design improvement will be discussed with r and d.
