Description of Event or Problem

IT WAS REPORTED TO BOSTON SCIENTIFIC CORPORATION THAT AN AXIOS STENT AND ELECTROCAUTERY ENHANCED DELIVERY SYSTEM WAS TO BE IMPLANTED TRANSGASTRIC TO PANCREAS TO TREAT A NECROTIC WALLED-OFF CYST DURING AN ENDOSCOPIC ULTRASOUND (EUS) PROCEDURE PERFORMED ON (B)(6) 2025. DURING THE PROCEDURE, THE AXIOS STENT WAS FULLY DEPLOYED; HOWEVER, THE STENT FIRST FLANGE DID NOT OPEN EVEN AFTER WAITING FOR A FEW MINUTES. THE INITIAL PUNCTURE SITE WAS CLOSED USING A CLIP. THE STENT WAS REMOVED USING RAT TOOTH FORCEPS, AND A DIFFERENT STENT WAS USED TO COMPLETE THE PROCEDURE. THERE WERE NO PATIENT COMPLICATIONS REPORTED AS A RESULT OF THIS EVENT.
