Investigation results: our quality engineer inspected the representative samples submitted for evaluation.Bd received 148 sealed 20ga x 1.00in.Insyte autoguard units from lot number 3270877.A sampling of 125 units were selected to be tested.A penetration and drag test was performed on (b)(4) which tests for catheter penetration, cannula penetration, and drag force.All units met specifications.In addition, retraction failure was also reported therefore a sampling of 20 units were tested.The 20 units were visually inspected, tip adhesion broke, and catheter slightly advanced before retracting the cannula.All units retracted successfully.The returned units provided for evaluation met and performed per the required manufacturing specifications.There was no physical/mechanical evidence to confirm and support a manufacturing process related issue for the failures stated in your report.A device history record review showed no non-conformances associated with this issue during the production of this batch.
