It was reported to boston scientific corporation on (b)(6) 2023, that an epic biliary endoscopic stent was to be implanted in the common bile duct to treat a cholangiocarcinoma during an endoscopic retrograde cholangiopancreatography (ercp) procedure performed on (b)(6) 2023.The patient's anatomy was not dilated prior to stent placement.During the procedure, the stent was unable to deploy after approximately 12 clicks on the thumb wheel.While removing the delivery catheter, the stent popped out, and a part of the stent was prematurely deployed in the common bile duct and the other part was deployed in the scope.The stent was removed from the patient together with the scope, and the procedure was completed with plastic stents.There were no patient complications reported as a result of this event.
