Block h6: medical device problem code a1502 captures the reportable event of stent positioning issue.Impact code f1903 captures the reportable surgery performed to explant the stent.Block h10: a wallstent enteral delivery system was received for analysis; the stent was not returned.Visual examination of the returned device found the outer blue sheath and clear sheath were kinked.No other problems were noted to the delivery system.The damage noted to the outer sheath was most likely due to procedural factors encountered during the procedure.It may be that lesion characteristics, handling of the device, the techniques used by the user, and/or normal procedural difficulties, limited the performance of the device.Therefore, contributing to the sheath becoming kinked.The reported event of stent positioning could not be confirmed; the event occurred during the procedure and it is not possible to replicate in the laboratory of analysis.A product labeling review identified that the device was used per the directions for use (dfu) / product label.Additionally, stent misplacement is noted within the manufacturers labeling as a known possible adverse event related to the use of the device.Therefore, a review and analysis of all available information indicated the most probable cause is known inherent risk of device.A review of the manufacturing documentation for this device revealed that no anomalies or deviations related to the event occurred during manufacturing.
