Manufacturer Narrative

Block h6: medical device problem code a27 is being used to capture the reportable issue of aborted/cancelled procedure.Block h10: an ultraflex esophageal ng distal release covered stent and delivery system were received for analysis.The stent was received partially deployed.Visual examination of the returned device found the shaft kinked in two sections.No other issues were noted to the stent and delivery system.Taking all available information into consideration, the investigation concluded that the reported event and observed failure were likely due to factors encountered during the procedure.It may be that the technique used by the user during the deployment of the stent could have caused the shaft kinked, limited the performance of the device and contributed to the stent partially deployed and difficulty crossing the lesion.Therefore, the most probable root cause is adverse event related to the procedure.A review of the manufacturing documentation for this device revealed that no anomalies or deviations related to the event occurred during manufacturing.A labeling review was performed and, from the information available, there is no information that this device was used in a manner inconsistent with the instructions for use (ifu) / product label.
