On 7/20/2016 integra investigation completed.Method: failure analysis, devices history evaluation.Results: failure analysis: the actual samples that were found to be broken and those that broke during use were not returned, however 18 kits from the same lot were returned and analyzed.All 18 kits were opened and inspected for damage that could indicate a root cause for the breaking glass syringes.During the inspection of the returned kits, only 1 glass syringe was found to have small cracking on the outer shaft of the syringe.The box used for shipping the glass syringes was also inspected for damage and damage along the sides was found.The cracked glass syringe was functionally tested for leaking using blue dye used for dye penetration leak testing per (b)(4) standards.No leaking was observed after multiple uses of the syringe.Slight hand force was applied to the male luer tip of the syringe and no further cracking or damage was observed.Devices history evaluation: the dhr was reviewed and no ncmr or other issue was found related to this complaint failure mode.Conclusion: the likely root cause for the damaged glass syringes is excessive mishandling during shipping.
