It was reported to boston scientific corporation that a advanix-naviflex rx biliary stent was to be implanted to treat a common bile duct (cbd) stricture in the section portion of duodenal, next to papilla during an endoscopic retrograde cholangiopancreatography (ercp) procedure performed on (b)(6) 2025.During the procedure the technician noted that pulling the rear wire did not advance the stent.Upon inspection, the locking mechanism was confirmed to be in the unlocked position.Another advanix-naviflex rx biliary stent was used to complete the procedure.There were no patient complications reported as a result of this event.Note: this complaint has been deemed mdr reportable event based on the investigation result which revealed that guide catheter was detached.Please see block h11 for the full investigation details.

Block h6: imdrf device code a0401 captures the reportable event of guide catheter break.Block h11: a advanix- naviflex biliary rx stent was received for analysis.Visual examination of the returned device found the guide catheter detached, the push catheter was observed kinked, the stent suture hole was torn, and the stent was kinked.Functional inspection was performed; it wasn't possible to retract or the pull wire.No other issues were noted with the stent and delivery system.Product analysis confirmed the reported event of stent failure to deploy, pull wire retraction problem, use of device issue - user error.The investigation concluded that the reported event and additional observed damages were most likely due to procedural factors such as lesion characteristics, handling of the device, and the technique used by the physician.The labeling review found evidence to suggest that the device was used in a manner inconsistent with the labelled indications.Per the ifu, "slide the outer orange sleeve over the most proximal stent barb to hold it down for stent insertion".However, it was reported that the barb flap cover was not used to insert the device through the biopsy cap.The ifu contains detailed device information and instructions for the device use and there is no evidence that there is any issue with translation, wording, or graphics of the ifu/labeling information.Therefore, the most probable root cause is failure to follow instructions.
