Additional Manufacturer Narrative

BLOCK H6: IMDRF DEVICE CODE A150201 CAPTURES THE REPORTABLE EVENT OF STENT FAILURE TO DEPLOY. BLOCK H11: FOLLOWING AN UPDATE TO THE AXIOS RISK DOCUMENTATION, THIS EVENT IS BEING REPORTED AS PART OF THE EFFORTS ASSOCIATED WITH BOSTON SCIENTIFIC'S NONCONFORMING EVENTS AND PREVENTION INVESTIGATION, (B)(4). INVESTIGATION RESULT: WITH THE INFORMATION AVAILABLE, BOSTON SCIENTIFIC CONCLUDES THAT THE REPORTED EVENT INVOLVING FAILURE OF THE STENT TO DEPLOY COULD NOT BE CONFIRMED. IN ADDITION, THE MANUFACTURING DOCUMENTATION REVIEW DID NOT IDENTIFY ANY ISSUES THAT COULD BE ASSOCIATED WITH THE REPORTED EVENT. DEVICE HISTORY RECORD REVIEW: A REVIEW OF THE MANUFACTURING DOCUMENTATION FOR THIS DEVICE REVEALED THAT NO ANOMALIES OR DEVIATIONS RELATED TO THE EVENT OCCURRED DURING MANUFACTURING. DEVICE TECHNICAL ANALYSIS: THE DEVICE WAS NOT RETURNED FOR ANALYSIS; THEREFORE, A TECHNICAL ANALYSIS COULD NOT BE PERFORMED. RISK REVIEW: A RISK REVIEW WAS COMPLETED AND CONFIRMED THAT THE EVENT OF "STENT FAILURE TO DEPLOY" WAS DEFINED IN THE RISK DOCUMENTATION. THIS EVENT TYPE HAS BEEN ACCOUNTED FOR DURING PRODUCT RISK ANALYSIS TO SUPPORT ACCEPTABLE RISK BENEFIT FOR THE PRODUCT. INVESTIGATION CONCLUSION: BASED ON THE AVAILABLE INFORMATION, THERE IS NOT ENOUGH EVIDENCE TO CONFIRM THE REPORTED EVENT. DUE TO THE LACK OF EVIDENCE AND WITHOUT PROPER EVALUATION OF THE COMPLAINT DEVICE, CAUSE NOT ESTABLISHED IS SELECTED AS THE MOST PROBABLE ROOT CAUSE.
