    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 4MM X 16MM ENTERPRISE 2 VASCULAR RECONSTRUCTION DEVICE WAS RECEIVED CONTAINED IN THE DECONTAMINATION POUCH. VISUAL INSPECTION WAS PERFORMED. THE STENT WAS OBSERVED DETACHED FROM THE DELIVERY SYSTEM. MICROSCOPIC INSPECTION WAS PERFORMED ON THE STENT COMPONENT. IT WAS OBSERVED TO BE IN GOOD CONDITION; THERE WAS NO STRUCTURAL DAMAGE (I.E., NO BROKEN STRUTS, NO KINKS). IT WAS ALSO NOTED TO BE FULLY EXPANDED WITH BOTH ENDS COMPLETELY FLARED. THE DELIVERY WIRE UNDERWENT DIMENSIONAL ANALYSIS, AND ALL MEASUREMENTS WERE FOUND TO BE WITHIN SPECIFICATIONS, INCLUDING THOSE SPECIFICATIONS THAT CONTROL THE ATTACHMENT AND DELIVERY OF THE STENT. THEREFORE, DEVICE FAILURE IS NOT SUSPECTED TO BE A CONTRIBUTING FACTOR. THE REPORTED ISSUE DOCUMENTED IN THE COMPLAINT REGARDING A STENT BEING PREMATURELY RELEASED WAS CONFIRMED SINCE THE STENT WAS NOTED AS ALREADY SEPARATED FROM THE DELIVERY SYSTEM; BASED ON THIS CONDITION, THE ISSUE REGARDING A STENT BEING IMPEDED IN THE DISTAL END OF THE CONCOMITANT MICROCATHETER CANNOT BE EVALUATED THROUGH FUNCTIONAL TESTING. THE STENT MUST BE INSIDE THE INTRODUCER TUBE TO PERFORM THE FUNCTIONAL ANALYSIS. ADDITIONALLY, NONE OF THE RETURNED COMPONENTS PRESENT DAMAGES THAT SUGGEST THAT THEY WERE FORCIBLY ADVANCED. WITH THE LIMITED INFORMATION AVAILABLE, A CONCLUSIVE CAUSE CANNOT BE DETERMINED; HOWEVER, IT IS POSSIBLE THAT CLINICAL AND PROCEDURAL FACTORS, INCLUDING DEVICE MANIPULATION AND OPERATOR'S TECHNIQUE, MAY HAVE CONTRIBUTED TO THE REPORTED FAILURE. AT THIS TIME, THERE IS NO EVIDENCE TO SUPPORT THAT THE ISSUE REPORTED IN THE COMPLAINT IS A RESULT OF A DEFECT INHERENTLY RELATED TO THE DEVICE. LAKE REGION MEDICAL PERFORMED A REVIEW OF THE DEVICE HISTORY RECORDS RELATIVE TO THE MANUFACTURING, INSPECTION, AND PACKAGING OF THE LOT 9061788. 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 PRODUCT FAILURE COULD BE CAUSED BY MULTIPLE FACTORS. THE INSTRUCTION FOR USE (IFU) DOES CONTAIN THE FOLLOWING RECOMMENDATIONS: - DO NOT PARTIALLY DEPLOY THE STENT FROM THE INTRODUCER. - DO NOT APPLY UNDUE FORCE IF RESISTANCE IS ENCOUNTERED AT ANY POINT DURING STENT MANIPULATION. WITHDRAW THE UNIT AND ADVANCE A NEW ONE. - CONFIRM THE TIP OF THE DELIVERY WIRE IS ENTIRELY WITHIN THE INTRODUCER. 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. 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.

    Description of Event or Problem · 0

    THE HEALTHCARE PROFESSIONAL REPORTED THAT DURING AN ENDOVASCULAR EMBOLIZATION PROCEDURE, THE 4MM X 16MM ENTERPRISE 2 VASCULAR RECONSTRUCTION DEVICE (VRD) (ENCR401600 / 9061788) WAS IMPEDED IN THE DISTAL END OF THE CONCOMITANT MICROCATHETER (UNSPECIFIED BRAND) AND COULD NOT PASS THROUGH THE MICROCATHETER. THE PHYSICIAN RETRACTED ONLY THE STENT, BUT THE STENT COMPONENT WAS FOUND PREMATURELY DETACHED FROM THE DELIVERY WIRE AFTER IT WAS OUT OF THE Y-CONNECTOR. THE PHYSICIAN REPLACED THE STENT AND COMPLETED THE PROCEDURE USING THE SAME MICROCATHETER. THERE WAS NO REPORT OF ANY NEGATIVE IMPACT ON THE PATIENT. ON 09-JAN-2026, ADDITIONAL INFORMATION WAS RECEIVED. THE INFORMATION INDICATED THAT THE PROCEDURE WAS TARGETING THE C7 SEGMENT OF THE INTERNAL CAROTID ARTERY. THE MICROCATHETER USE WAS A CERENOVUS MICROCATHETER, BUT THE CATALOG AND LOT NUMBER CANNOT BE OBTAINED. A CONTINUOUS FLUSH WAS MAINTAINED THROUGH THE MICROCATHETER. ASIDE FROM THE REPORTED PREMATURE DETACHMENT OF THE STENT, NO ADDITIONAL DAMAGE WAS NOTED ON THE STENT / STENT DELIVERY SYSTEM. THE REPLACEMENT STENT WAS ANOTHER 4MM X 16MM ENTERPRISE 2 VASCULAR RECONSTRUCTION DEVICE (ENCR401600). THE INFORMATION CONFIRMED THERE WAS NO DELAY IN THE PROCEDURE.
