    MANUFACTURER REF#: (B)(4). UPDATED SECTIONS ON THIS MEDWATCH: B4, G3, G6, H2, H3, H6 AND H11. COMPLAINT CONCLUSION: AS REPORTED BY THE FIELD, DURING AN ENDOVASCULAR EMBOLIZATION, A 4.5MMD X 22MML ENTERPRISE INTRACRANIAL STENT (ENC452200, 9020399) BECAME IMPEDED IN INTRODUCER AND COULD NOT ADVANCE ANY MORE. THE STENT WAS FOUND DETACHED FROM THE DELIVERY WIRE IN THE INTRODUCER. THE DOCTOR SWITCHED TO A NEW STENT TO COMPLETE THE SURGERY. THE MICROCATHETER WAS NOT REPLACED. THERE WAS NO PATIENT INJURY REPORT. ADDITIONAL EVENT INFORMATION RECEIVED ON 07-APR-2025 INDICATED THAT THERE WAS NO EVIDENCE OF PHYSICAL MATERIAL WITHIN THE DEVICE. THE MICROCATHETER USED WAS A PROWLER SELECT PLUS (606S255, 31351022). THE MICROCATHETER DID NOT KINK/BENT. THERE WAS NO EXCESSIVE FORCE USED WITH THE DEVICES. THERE WERE NO PROCEDURAL DELAYS DUE TO THE EVENT. THE DEVICE WAS RETURNED TO J&J MEDTECH FOR FURTHER EVALUATION. A NON-STERILE 4.5MMD X 22MML ENTERPRISE INTRACRANIAL STENT WAS RECEIVED CONTAINED IN THE DECONTAMINATION POUCH. UPON RECEIVING THE DEVICE, A VISUAL INSPECTION WAS PERFORMED, AND IT WAS NOTED THAT THE STENT WAS ALREADY DETACHED FROM THE UNIT, AND THIS REMAINED INSIDE THE PROXIMAL PORTION OF THE INTRODUCER. THE DELIVERY WIRE AND THE INTRODUCER WERE IN GOOD CONDITION (I.E., NO KINKS, BENTS, OR ELONGATIONS). MICROSCOPIC INSPECTION WAS PERFORMED ON THE STENT COMPONENT. IT WAS OBSERVED TO BE IN GOOD CONDITION; THERE WAS NO STRUCTURAL DAMAGE. THE DELIVERY WIRE WAS SUBJECTED TO DIMENSIONAL ANALYSIS AND ALL MEASUREMENTS WERE FOUND TO BE WITHIN SPECIFICATION, INCLUDING THOSE SPECIFICATIONS THAT CONTROL THE ATTACHMENT AND DELIVERY OF THE STENT. THEREFORE, DEVICE FAILURE IS NOT SUSPECTED TO BE A CONTRIBUTING FACTOR. THE CUSTOMER COMPLAINT REGARDING A STENT BEING RELEASED WAS CONFIRMED DUE TO THE DETACHED CONDITION OF THE STENT, HOWEVER, BASED ON THIS CONDITION THE ISSUE REGARDING A STENT BEING IMPEDED IN THE INTRODUCER 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 DID REVIEW THE DEVICE HISTORY RECORDS RELATIVE TO THE MANUFACTURING, INSPECTING AND PACKAGING OF THE LOT 9020399. THE HISTORY RECORDS INDICATE THIS PRODUCT WAS FINAL INSPECTION TESTED AT LAKE REGION MEDICAL AND WAS DETERMINED TO BE ACCEPTABLE. AS PART OF THE J&J MEDTECH QUALITY PROCESS, ALL DEVICES ARE MANUFACTURED, INSPECTED, AND RELEASED TO APPROVED SPECIFICATIONS. SINCE THERE WAS NO EVIDENCE TO SUGGEST THE EVENT WAS RELATED TO A MANUFACTURING OR DESIGN ISSUE, NO CAPA ACTIVITY IS REQUIRED. IT SHOULD BE NOTED THAT PRODUCT FAILURE COULD BE CAUSED BY MULTIPLE FACTORS. THE INSTRUCTIONS FOR USE (IFU) DO CONTAIN THE FOLLOWING RECOMMENDATIONS: ¿ IF RESISTANCE IS MET DURING MANIPULATION, DETERMINE THE CAUSE OF RESISTANCE BEFORE PROCEEDING. ¿ DO NOT APPLY UNDUE FORCE IF RESISTANCE IS ENCOUNTERED AT ANY POINT DURING STENT MANIPULATION. WITHDRAW THE UNIT AND ADVANCE A NEW ONE. AS PART OF THE POST MARKET SURVEILLANCE PROGRAM, INFORMATION FROM THIS COMPLAINT IS TRENDED TO IDENTIFY STATISTICAL SIGNALS FOR CONSIDERATION OF FURTHER CORRECTION ACTION. 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. A SUPPLEMENTAL REPORT WILL BE SUBMITTED IF NEW FACTS ARISE WHICH MATERIALLY ALTER INFORMATION SUBMITTED IN A PREVIOUS MDR REPORT.
