    MANUFACTURER¿S REF. NO: (B)(4). THE PURPOSE OF THIS MDR SUBMISSION IS TO REPORT THE INVESTIGATIONAL FINDING OF THE RETURNED DEVICE. THE COMPLAINT PRODUCT WAS RETURNED AND RECEIVED FOR EVALUATION AND ANALYSIS. THE INVESTIGATION IS DOCUMENTED BELOW. INVESTIGATION SUMMARY: A NON-STERILE 4.5MM X 22MM ENTERPRISE® VASCULAR RECONSTRUCTION DEVICE WAS RECEIVED CONTAINED IN THE DECONTAMINATION POUCH. VISUAL INSPECTION WAS PERFORMED. THE STENT COMPONENT WAS STILL ATTACHED TO THE DELIVERY WIRE AND INSIDE THE INTRODUCER. NO APPEARANCE OF DAMAGE WAS NOTED. MICROSCOPIC INSPECTION REVEALED NO DAMAGES ON THE STENT NOR THE DELIVERY WIRE. A FUNCTIONAL TEST WAS PERFORMED. A LAB SAMPLE OF THE PROWLER SELECT PLUS WAS FLUSHED USING A LAB SYRINGE. THE UNIT WAS THEN INSERTED INTO THE PROWLER SELECT PLUS, AND IT ADVANCED SMOOTHLY WITHOUT ANY RESISTANCE OR FRICTION AS THE STENT PASSED THROUGH. THE STENT SUCCESSFULLY EXITED FROM THE DISTAL TIP OF THE MICROCATHETER. THE FUNCTIONAL TEST WAS PERFORMED WITHOUT ISSUES, THE REPORTED IMPEDED CONDITION ENCOUNTERED DURING THE PROCEDURE AND THE DAMAGE ON THE ENTERPRISE SYSTEM COULD NOT BE CONFIRMED. HOWEVER, THERE MAY HAVE BEEN OTHER CIRCUMSTANCES OR ISSUES THAT OCCURRED DURING THE USE OF THE DEVICE THAT COULD NOT BE REPLICATED DURING THE ANALYSIS. LAKE REGION MEDICAL PERFORMED A REVIEW OF THE DEVICE HISTORY RECORDS RELATIVE TO THE MANUFACTURING, INSPECTION, AND PACKAGING OF THE LOT 9061886. THE HISTORY RECORD INDICATES THIS PRODUCT WAS FINAL INSPECTION TESTED AT LAKE REGION MEDICAL AND WAS DETERMINED TO BE ACCEPTABLE. AS PART OF JOHNSON & JOHNSON MEDTECH QUALITY PROCESS, ALL DEVICES ARE MANUFACTURED, INSPECTED, AND RELEASED TO APPROVED SPECIFICATIONS. IT SHOULD BE NOTED THAT MULTIPLE FACTORS COULD CAUSE PRODUCT FAILURE. THE INSTRUCTION FOR USE (IFU) DOES CONTAIN THE FOLLOWING RECOMMENDATIONS: THE INTRODUCER MUST BE PROPERLY ENGAGED WITH THE INFUSION CATHETER HUB TO ENABLE STENT INTRODUCTION INTO THE INFUSION CATHETER. DO NOT APPLY UNDUE FORCE IF RESISTANCE IS ENCOUNTERED AT ANY POINT DURING STENT MANIPULATION. WITHDRAW THE UNIT AND ADVANCE TO A NEW ONE. IF RESISTANCE IS FELT WHILE RECAPTURING THE STENT, DO NOT CONTINUE TO RECAPTURE THE DEVICE. WITHDRAW THE INFUSION CATHETER SLIGHTLY TO UNSHEATHE THE STENT (WITHOUT EXCEEDING THE RECAPTURE LIMIT), AND THEN ATTEMPT TO RECAPTURE THE STENT AGAIN. BASED ON THE MANUFACTURING DOCUMENTATION REVIEW, THERE IS NO INDICATION THAT THE EVENT IS RELATED TO THE DEVICE MANUFACTURING PROCESS. AS PART OF THE POST MARKET SURVEILLANCE PROGRAM, INFORMATION FROM THIS COMPLAINT IS TRENDED FOR STATISTICAL SIGNALS AND CORRECTIVE / PREVENTIVE ACTION MAY BE TRIGGERED AT A LATER TIME. SINCE THERE WAS NO EVIDENCE TO SUGGEST THE EVENT WAS RELATED TO A MANUFACTURING OR DESIGN ISSUE, NO CORRECTIVE ACTIONS WILL BE TAKEN AT THIS TIME. UPDATED SECTIONS: B.4, G.3, G.6. H.2, H.3, H.6, AND H.11. THE MANUFACTURER WILL SUBMIT A SUPPLEMENTAL REPORT IF NEW FACTS ARISE WHICH MATERIALLY ALTER INFORMATION SUBMITTED IN A PREVIOUS MDR REPORT. ADDITIONAL INFORMATION WILL BE SUBMITTED WITHIN 30 DAYS OF RECEIPT.
