Investigation summary: since no samples displaying the condition reported were available for examination, we were unable to fully investigate this incident.Observations and testing could not be performed because units were not provided for investigation.A lot history review was carried out and no related non conformances were raised in association with this packaged lot concluding all inspections were performed per the applicable operations and met qc specifications.The lot number 8087800 is currently being investigated further for review of the safety shield activation failure.Investigation conclusion: the root cause was related to manufacturing.This is an issue with the safety feature of the device.Although occurrence is low and all reported incidents thus far have limited severity (contaminated needle stick injury with no known blood borne pathogen), there is the potential for higher severity end user effects.Capa #(b)(4) has been opened to address this incident.Capa (b)(4) problem statement: the tip shield did not properly capture the tip of some nexiva 18 ga needle between the v-clip and washer.Instead, due to the failure mode of bump out of specification (small or missing), the needle pulled through the washer and allowed the gray tip shield to disconnect from the needle assembly.Correction: due to an it issue beginning on 7/3/2018, previously filed emdrs did not contain required fields.This supplemental emdr is filed to provide the following omitted fields: event attributed to: other, device single use?: no, device returned to manufacturer: no.
