Event Description

It was reported to boston scientific corporation on (b)(6) 2019 that an ultraflex tracheobronchial stent covered distal release stent was to be used to treat a stenosis in the left main bronchus during a tracheal stent implantation procedure performed on (b)(6) 2019.Reportedly, the patient's anatomy was dilated prior to stent placement.According to the complainant, during the procedure, the stent was able to be deployed; however, the distal end of the stent was not fully expanded and it blocked the passage of the scope.Per the physician, the stent failed to clear the airway granulation tissue and did not dilate the stenosis.The stent was removed with forceps and another ultraflex tracheobronchial stent was placed to complete the procedure.There were no patient complications reported as a result of this event.The patient's condition at the conclusion of the procedure was reported to be stable.

Block h6: problem code 3270 captures the reportable event of stent failed to expand.Block h10: an ultraflex tracheobronchial covered stent was received for analysis; however, the delivery system and deployment suture were not returned.Visual examination of the returned device found the stent was received deployed and expanded.The stent was measured to be within specifications.No other issues were noted to the stent.Taking all available information into consideration, the investigation concluded that the reported event was likely due to procedural factors such as handling of the device, the technique used by the user, and normal procedural difficulties encountered during the procedure, which limited the performance of the device.Therefore, the most probable root cause is adverse event related to procedure.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly, and performance specifications at the time of release for distribution.
