• MalfunctionFeb 18, 2026Separation Failure

  MEDTRONIC RECEIVED A REPORT THAT A MICROCATHETER WAS ACCESSED INTO THE ANEURYSM, AND AFTER THE CORRESPONDING AXIUM COIL WAS DEPLOYED, DETACHMENT WAS ATTEMPTED BUT THE COIL COULD NOT BE DETACHED. EMERGENCY DETACHMENT WAS ALSO UNSUCCESSFUL, SO THE COIL WAS REMOVED AND DISCARDED ALONG WITH THE DETACHER WITHIN THE HOSPITAL. AXIUM COIL DETACHMENT FAILURE OCCURRED. EMERGENCY DETACHMENT WAS ALSO ATTEMPTED BUT WAS NOT POSSIBLE. THERE WAS POOR DISLODGEMENT. THE PHYSICIAN ATTEMPTED TO DETACH THE COIL USING THE INSTANT DETACHER 5 TIMES. THE PHYSICIAN DID NOT ATTEMPT TO WITHDRAW USING ANOTHER INSTANT DETACHER. THERE WAS 1 ATTEMPT (EMERGENCY WITHDRAWAL) MADE TO REMOVE THE DEVICE MANUALLY VIA THE HYPOTUBE. THE PRODUCT WAS NOT USED IN AN INFECTED PATIENT. THE DEVICE WAS PREPARED AS INDICATED IN THE PACKAGE INSERT. NO PATIENT SYMPTOMS OR COMPLICATIONS ASSOCIATED WITH THIS EVENT WERE REPORTED.

• MalfunctionJul 11, 2025Use of Device Problem; Separation Failure; Use of Device Problem; Separation Failure

  MEDTRONIC RECEIVED A REPORT THAT DURING COIL EMBOLIZATION OF A CEREBRAL ANEURYSM, THE AXIUM COIL WAS USED AS THE FIRST COIL FOR EMBOLIZATION. AFTER SEVERAL REWINDING ATTEMPTS, DETACHMENT WAS ATTEMPTED BUT COULD NOT BE ACHIEVED. THE BEHAVIOR SUGGESTED UNRAVELING, AND THE PHYSICIAN DETERMINED IT TO BE A MALFUNCTION AND PERFORMED RETRIEVAL. THE COIL WAS SUCCESSFULLY RETRIEVED, BUT UPON EXAMINATION OF THE RETRIEVED COIL, A BLUE WIRE WAS VISIBLE. SUBSEQUENTLY, EMBOLIZATION WAS CONTINUED USING A DIFFERENT LOT OF COILS FROM THE SAME COMPANY. THE PHYSICIAN ATTEMPT TO DETACH THE COIL USING THE INSTANT DETACHER (ID) TWICE, IT WAS UNKNOWN IF THE ID HAD ANY DEFECTS. THEY DID NOT ATTEMPT TO WITHDRAW USING ANOTHER INSTANT DETACHER AND IT WAS UNKNOWN IF THERE WAS AN ATTEMPT MADE TO REMOVE THE DEVICE MANUALLY VIA THE HYPOTUBE. 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.

  MEDTRONIC RECEIVED INFORMATION THAT AN AXIUM COIL HAD RESISTANCE, IN THE ECHELON CATHETER, DETACHED PREMATURELY, AND WAS STRETCHED. AFTER THE MICROCATHETER REACHED THE ANEURYSM, THE SURGEON STARTED FILLING THE COIL. THE 3DCOIL OF APB-5-15 WAS THE FIRST TO BE SELECTED, AND PLANNED TO FORM A HOOP. AFTER TAKING OUT THE COIL AND HYDRATING IT, THE COIL STARTED TO BE DELIVERED. BEFORE THE COIL CAME OUT OF THE TIP OF THE MICROCATHETER, IT WAS FOUND THAT THE RESISTANCE WAS TOO LARGE TO BE DELIVERED IN. AT THAT TIME, ONLY PART OF THE PUSH ROD WAS DELIVERED INTO THE MICROCATHETER. AFTER FINDING THAT THE RESISTANCE WAS TOO LARGE, THE SURGEON WAS WORRIED ABOUT SAFETY AND DID NOT CONTINUE THE DELIVERY, AND STOPPED FOR 30 SECONDS. THE SURGEON INJECTED NORMAL SALINE INTO THE MICROCATHETER, AND CONTINUED TO PUSH, BUT THE RESISTANCE WAS STILL VERY LARGE. THEN, THE COIL BODY AND PUSH ROD WERE BROKEN DURING THE SURGEON'S WITHDRAWAL THE COIL PROCESS. THE SURGEON FINALLY WITHDREW THE COIL BODY FROM THE INTRODUCER SHEATH, AND THE COIL HAD BEEN STRETCHED DURING THE WITHDRAWAL PROCESS. DURING THE DELIVERY PROCESS, PART OF THE COIL ENTERED INTO THE MICROCATHETER AND IT HAD NOT YET CAME OUT FROM THE TIP, SO

  MEDTRONIC RECEIVED INFORMATION THAT AN AXIUM COIL DETACHED PREMATURELY IN THE MICROCATHETER AND IT MIGRATED INTO THE MIDDLE CEREBRAL ARTERY, CAUSING AN OCCLUSION. THE PATIENT WAS BEING TREATED FORM A RUPTURED SACCULAR ANEURYSM IN THE LEFT INTERNAL CAROTID ARTERY. THE MAX DIAMETER WAS 8MM AND THE NECK DIAMETER WAS 6MM. PATIENT BLOOD FLOW WAS NORMAL AND VESSEL TORTUOSITY WAS MODERATE. WHILE ATTEMPTING TO PLACE THIS AXIUM COIL, THE MICROCATHETER KICKED OUT OF THE ANEURYSM. THE PHYSICIAN RODE THE MICROCATHETER OVER THE COIL TO RE-ENTER THE ANEURYSM. ONCE BACK INSIDE THE ANEURYSM HE NOTICED THE COIL WAS NOT MOVING WITH MULTIPLE ATTEMPTS TO ADVANCE OR WITHDRAW. HE THEN NOTICED THE COIL HAD DETACHED FROM THE MICROCATHETER EARLY. AN ATTEMPT WAS MADE WITH A TULIP SNARE TO SNARE THE COIL BUT THIS WAS UNSUCCESSFUL AND THE COIL MIGRATED INTO THE MIDDLE CEREBRAL ARTERY, CAUSING AN OCCLUSION. A SOLITAIRE WAS THEN DEPLOYED ACROSS THE COIL AND RETRACTED INTO A GUIDE CATHETER UNDER ASPIRATION TO SUCCESSFULLY REMOVE THE COIL FROM THE PATIENT. THE COIL WAS REMOVED FROM THE PATIENT WITH A SOLITAIRE. COIL WAS REMOVED VIA A SOLITAIRE AND PATIENT WAS PLACED ON BLOOD THINNERS DUE TO THE OCCLUSION THE COIL
