THE DOCTOR COULD NOT SEE THE MARKS WHEN THE STENT WAS POSITIONED AND WANTED TO RELEASE IT.

THE DSA MACHINE USED DURING THE PROCEDURE WAS A GE INOVA 3100 AN ADVANCED MACHINE THAT SOMETIMES CAN DISPLAY MESH OF ENTERPRISE STENT.

    THE COMPLAINT RECEIVED STATES THAT DURING AN ANEURYSM COIL EMBOLIZATION THE ENTERPRISE STENT HAD INACCURATE DEPLOYMENT AND HAD INADEQUATE RADIOPACITY AND THAT POST PROCEDURE THE PATIENT SUFFERED A CEREBRAL INFARCTION. THIS IS A (B)(6) FEMALE PATIENT WITH UNKNOWN MEDICAL HISTORY. THE DIAMETER OF THE VESSEL WITH THE ANEURYSM IS 3.7MM. DURING A COIL EMBOLIZATION PROCEDURE ASSISTED WITH ENTERPRISE STENT, THE ENTERPRISE 4.5X22 STENT WAS IMPLANTED AFTER PROWLER SELECT PLUS WAS POSITIONED. THE DELIVERING PROCESS WAS SUCCESSFUL, BUT THE DISTAL AND PROXIMAL MARKS COULD NOT BEEN SEEN WHEN THE STENT WAS RELEASED. THE MICRO GUIDE CATHETER WAS REMOVED AND TRUFILL COIL (638MF0407) WAS DETACHED USING THE MICROCATHETER, ONLY TO FIND THERE WAS NO STENT SUPPORTING THE NECK. THE STENT COULD NOT BE LOCATED ON DSA TEST OR IN CT TEST. THE DECISION WAS MADE TO IMPLANT ANOTHER ENTERPRISE (ENC452812) STENT WITH MARKERS COULD BE SEEN CLEARLY. FOUR ORBIT COILS (637MF0304, 637HF0206, 637HF0204, AND 637HF0204) WERE IMPLANTED TO COMPLETE THE PROCEDURE SUCCESSFULLY. THE PATIENT SUFFERED SEVERE INFARCTION OF THE BRAIN AFTER THE PROCEDURE. THE SURGEON FOLLOWED THE INSTRUCTIONS FOR USE STRICTLY (PINCHED THE PROTECTION SHEATH WHEN TAKING THE STENT OUT), AND RECALLS THAT THERE WAS A STENT ABOVE THE DELIVERING CATHETER VAGUELY, BUT DID NOT PAY ATTENTION TO IT WHEN HE PUT IT INTO THE VESSEL. THE DOCTOR COULD NOT SEE THE MARKS WHEN THE STENT WAS POSITIONED AND WANTED TO RELEASE IT. HOWEVER, HE ALSO WITHDREW THE PROWLER PLUS, AND RELEASED THE STENT, AND IMPLANTED 638MF0407, ONLY TO FIND THERE WAS NO STENT SUPPORTING THE NECK. THE DSA MACHINE USED DURING THE PROCEDURE WAS A GE INOVA 3100 AN ADVANCED MACHINE THAT SOMETIMES CAN DISPLAY MESH OF ENTERPRISE STENT. AFTER THE EVENTS, WITH FOLLOW-UP ANGIOGRAM, RESIDUAL FLOW WAS NOTED IN THE ANEURYSM. THERE IS NO STERILE LOT NUMBER INFORMATION AVAILABLE THUS NO DHR COULD BE PERFORMED. THE FAILURES OF STENT INADEQUATE RADIOPACITY-MARKERS AND STENT DEPLOYMENT DIFFICULTY-INACCURATE PLACEMENT REPORTED BY THE CUSTOMER WERE NOT CONFIRMED SINCE THE STENT WAS NOT RETURNED FOR ANALYSIS. THE DELIVERY DEVICE DID NOT PRESENT ANY OBVIOUS INDICATION OF MANUFACTURING DEFECT OR ANOMALY THAT COULD CONTRIBUTED TO THE EVENT AS REPORTED. NEITHER THE PRODUCT ANALYSIS NOR THE DHR REVIEW SUGGESTS THAT THE FAILURES COULD BE RELATED TO THE ENTERPRISE MANUFACTURING PROCESS; THEREFORE, NO CORRECTIVE ACTION WILL BE TAKEN AT THIS TIME. CEREBRAL INFARCTION IS KNOWN POTENTIAL ADVERSE EVENT ASSOCIATED WITH NEUROVASCULAR STENT IMPLANTATION PROCEDURES AND IS LISTED IN THE IFU AS SUCH. THE ACT OF CEREBRAL STENT IMPLANTATION INHERENTLY PRODUCES A LOCALIZED VESSEL INJURY POTENTIALLY LEADING TO RELEASE OF ATHEROMATOUS MATERIAL INTO THE DOWNSTREAM FLOW OR VESSEL SPASM IN REACTION TO THE INTRODUCTION OF THE DEVICES THAT MAY SLOW OR COMPLETELY OCCLUDE THE BLOOD FLOW. THE INTRODUCTION OF INTERVENTIONAL DEVICES AND STENT IMPLANTATION MAY LEAD TO A SLOWING OR STOPPAGE OF BLOOD FLOW TO THE DOWNSTREAM VESSELS AND STRUCTURES OF THE BRAIN CAUSING INFARCTIONS OF THESE STRUCTURES. THERE IS NO EVIDENCE OF MANUFACTURING ISSUES THAT MAY HAVE CONTRIBUTED TO THE REPORTED EVENT; THEREFORE, NO CORRECTIVE ACTION IS REQUIRED AT THIS TIME. THIS ACTION (INHERENT RISK OF THE PROCEDURE) COMBINED WITH PROCEDURAL FACTORS MAY HAVE CONTRIBUTED TO THE EVENT. THIS IS ONE OF TWO PRODUCTS USED DURING THE SAME PROCEDURE ON THE SAME PATIENT, WHICH IS ASSOCIATED WITH MFR REPORT 1058196-2011-00205 AND 1058196-2011-00206.
