    Description of Event or Problem · 0

    MEDTRONIC RECEIVED A REPORT THAT THE PATIENT WAS UNDERGOING WHOLE BRAIN ANGIOGRAPHY AND THROMBECTOMY OPERATION FOR ISCHEMIC STROKE M2 SEGMENT OCCLUSION TREATMENT. THE SITE OF INTRACRANIAL VASCULAR OCCLUSION WAS DETERMINED BY ANGIOGRAPHY. IT WAS NOTED THAT THE PATIENT¿S VESSEL TORTUOSITY WAS MODERATE. THE STROKE ONSET TO REPERFUSION TIME WAS 40MIN IT WAS REPORTED THAT THE GUIDE SHEATH, NEUROVASCULAR GUIDEWIRE, THROMBUS ASPIRATION CATHETER, REBAR18 MICROCATHETER, AND INTRACRANIAL VASCULAR STENT SAB-6-30 WERE SELECTED. AFTER THE PREPARATION WORK WAS COMPLETED, THE REBAR 18 MICROCATHETER WAS SUCCESSFULLY PUT IN PLACE. THE SURGEON SELECTED THE INTRACRANIAL VASCULAR STENT SAB-6-30 AND MOISTENED IT IN VITRO. DURING THE DELIVERY PROCESS OF SLOWLY PUSHING THE STENT, IT WAS FOUND THAT THE RESISTANCE TO PUSHING THE STENT GRADUALLY INCREASED AT THE PROXIMAL SECTION OF THE CATHETER, AND FINALLY THE STENT COULD NOT BE PUSHED FURTHER. IT WAS FOUND THAT THE TAIL OF THE STENT WAS CLOGGED AT THE TAIL OF THE MICROCATHETER. THE SURGEON TRIED MANY TIMES BUT FAILED TO PUSH IT. TWO NEW REBAR18 MICROCATHETERS WERE USED INSTEAD FOR DELIVERY, BUT THEY COULD NOT BE PUSHED IN PLACE. BECAUSE THE PATIENT WAS ALREADY IN A COMA AND THE SITUATION WAS CRITICAL, A NEW SAB-6-30 STENT W AS FINALLY USED INSTEAD, SUCCESSFULLY PUSHED IN PLACE, AND THE THROMBUS WAS REMOVED. AFTER THE OPERATION, THE SURGEON THOUGHT THAT THIS SITUATION HAD NEVER OCCURRED WHEN USING SAB-6-30 BEFORE. AFTER REPLACING THE MICROCATHETER, IT STILL COULD NOT BE PUSHED NORMALLY, AND THE SURGEON FILED A COMPLAINT THAT IT WAS A PRODUCT QUALITY ISSUE. THE REPORTED DEVICE AND ANY ACCESSORY DEVICES WERE PREPARED AS INDICATED IN THE INSTRUCTIONS FOR USE (IFU). NO PATIENT SYMPTOMS OR COMPLICATIONS WERE ASSOCIATED WITH THIS EVENT.
