Results: bd's quality engineer inspected the returned unit and confirmed the package was received open/partially peeled.The analysis conducted revealed an adequate amount of top web adhesive which was within specifications.The returned device was tested and retraction was successful as there was no delayed reaction to the needle retracting.We were unable to determine a root cause for this incident based on the provided sample.The samples were visually and microscopically evaluated and the customer's indicated failure mode for leakage with the incident lot was observed.A device history record review showed no non-conformances associated with this issue during the production of this batch.Conclusion: the defect package seal integrity poor/questionable, as stated in the description of the complaint was confirmed with the returned unit.Even though the package was partially opened, all the processes characteristics that directly influence the seal strength were observed to be within specification.No anomalies were found.The defect of needle retraction failure as stated as the reported coded was not confirmed with the returned units.No physical mechanical evidence was found to trigger the failure and the unit successfully retracted upon activation of the white button.Package seal integrity: although the packages were observed to be partially opened, there was no physical evidence to confirm or to support manufacturing process related issues for the defect.Needle retraction failure: the returned units did not display any adverse characteristics that would contribute to the defect the customer experienced.The defect that was described could not be confirmed or replicated with the returned representative unit.The actual unit described in the incident report was not returned for evaluation.Refer to (b)(4).
