H.6.Investigation summary: device/batch history record review findings: lot 7199367 was built on afa line 9 from 28jul2017 through 01aug2017 and packaged on packaging line 11 from 01aug2017 through 02aug2017 for the quantity of (b)(4).It was concluded that all required challenges samples and testing was performed per specification in accordance with the set-up and in process sampling plans.It was noted that there were no reject activity findings throughout the build of this lot that would impact upon the quality of the product.Set-up and in-process inspections included but were not limited to blister thickness, bad seal/cut/holes, seal transfer width and package leak test.These were performed on various stages throughout the process, all the inspections passed per specifications.Sap (qn) database review findings: subject code was an s1 severity ranking.Review was conducted for this mdr-level a investigation which disclosed the following: there were no reject activity findings relevant to the defect stated in the pir associated with the lot number provided for this incident.Peura (end user risk analysis) was analyzed to determine the risk to customer.The analysis showed that current risk is acceptable.Occurrence and severity rankings have not changed.Observations and testing: received one unused 18ga bd insyte autoguard blood control catheter unit within a partially opened package from lot 7199367.All components were present and intact with the blister pack was partially opened at both ends.There was a pink discoloration to the top of the package at the top web (tyvek), near the lot number/expiry date.Visual/microscopic examination: observed that although the unit package had a partially opened seal at the top and bottom of the blister pack, the sterility barrier was not compromised and the unit package (blister pack) demonstrated to have had an adequate seal with no anomalies at time of manufacturing.The product characteristics require a minimum of 1/8¿ seal transfer.This characteristic was met.In addition the paper top web of the returned unit was analyzed under uv light.The adhesive used to seal the top and bottom webs is uv fluorescent.The analysis revealed adequate top web adhesive.The key variables that affect seal strength are: seal transfer/width and top web adhesive presence.Both of these variables were included in the investigation.Conclusions: confirmation of the defect of package seal integrity poor / questionable, stated in the description of the complaint was conclusive with the unit provided for this incident; as the unit was received with partially opened packaging (blister pack).Although the package was received partially opened at the top and bottom, all the process characteristics that directly influence the seal strength were observed to be within specification.No anomalies were found.There was no physical evidence to confirm or to support manufacturing process related issues for the defect.Capa 48637 was initiated to address the issue of open seal complaints.Tasks associated with the capa plan have been completed.
