MEDTRONIC RECEIVED A REPORT THAT THERE WAS NO ALLEGED PRODUCT ISSUE, HOWEVER, 4 COILS WERE USED, AND ON FOLLOW-UP CT IT WAS NOTICED THAT THE FILAMENT WAS STILL ATTACHED TO THE COIL AND FLOATING IN THE VESSEL. THE CASE WENT WELL, PATIENT CAME BACK IN PRESENTING WITH ABDOMINAL PAIN, DISCUSSED INTERVENING AND TRYING TO SNARE THE FILAMENT BUT DECIDED AGAINST IT. UNSURE/NOT CONFIDENT THAT THE ABDOMINAL PAIN WAS RELATED. IT WAS UNKNOWN WHAT CONDITION WAS BEING TREATED. IT WAS NOTED THE PATIENT'S BLOOD FLOW AND VESSEL TORTUOSITY WERE NORMAL. THE REPORTED DEVICE AND ANY ACCESSORY DEVICES WERE PREPARED AS INDICATED IN THE INSTRUCTIONS FOR USE (IFU). ADDITIONAL INFORMATION WAS RECEIVED STATING THAT THE LESION WAS A PSEUDO-ANEURYSM IN THE INFERIOR PANCREATICODUODENAL REGION. WHEN THE PRESENCE OF THE FILAMENT WAS NOTED, THE DECISION WAS MADE TO ADMINISTER ANTICOAGULANTS RATHER THAN RE-INTERVENE. ANTICOAGULANTS WERE GIVEN ON (B)(6) TO ADDRESS BOTH THE FILAMENT AND THE ABDOMINAL PAIN, WHICH BEGAN ON (B)(6) AND RESOLVED BY (B)(6). THE IMPLANT PROCEDURE WAS BELIEVED TO HAVE OCCURRED ON (B)(6), WITH FOLLOW-UP CT IMAGING PERFORMED ON (B)(6). REGARDING THE COILS, IT WAS REPORTED THAT FOUR CONCERTO HELIX 4MM X 8CM COILS (MODEL NUMBER: NV-4-8-HELIX, LOT NUMBER: 230942604) WERE IMPLANTED, BUT ONLY ONE HAD THE FILAMENT STILL ATTACHED. ADDITIONAL COILS INCLUDED NV-6-20-HELIX (LOT: 232195914), NV-4-8-HELIX (LOT: 231168010) X2, AND NV-4-8-HELIX (LOT: 227894258), THOUGH IT IS UNCLEAR WHICH SPECIFIC DEVICE WAS INVOLVED IN THE ISSUE. THE CAUSE OF THE NON-DETACHMENT OF THE COIL FILAMENT WAS NOT DETERMINED, THOUGH POSSIBLE OPTIONS WERE DISCUSSED WITH ENGINEERING. THE CAUSE OF THE ABDOMINAL PAIN IS STILL TO BE DETERMINED. ONE ATTEMPT WAS MADE TO DETACH THE COIL USING THE INSTANT DETACHER AND ONE ATTEMPT USING THE MANUAL METHOD, AS PER USUAL PRACTICE. NO ISSUES WERE ENCOUNTERED PRIOR TO THE FILAMENT NON-DETACHMENT, AND NO PUSHWIRE DAMAGE WAS OBSERVED AFTER REMOVAL FROM THE PATIENT.
ADDITIONAL INFORMATION RECEIVED REPORTED THAT THE COIL WAS DETACHED USING THE DETACHER. IT WAS STATED THAT THE PATIENT HAD PRESENTED WITH ABDOMINAL PAIN AND THE AREA COILED WAS AN INCIDENTAL FINDING THAT COULD HAVE BEEN THE CAUSE AND SO THE COILING PROCEDURE WAS DONE. THE PATIENT RETURNED WITH ABDOMINAL PAIN, BUT THE DOCTOR DID NOT KNOW IF IT WAS THE SAME PAIN OR DIFFERENT. THE ABDOMINAL CT FOUND THE FILAMENT EXTENDING FROM THE INITIAL COIL THROUGH THE OTHER COILS INTO THE AORTA AND DOWN INTO THE EXTERNAL ILIAC AREA. IT IS NOT KNOWN IF ANTICOAGULANTS WERE ADMINISTERED.
