Manufacturer Narrative

Blocks d4 (lot number and expiration date), and h4 have been updated based on the additional received on january 05, 2022.Block h6: medical device problem code a15 captures the reportable event of partially deployed ultraflex esophageal proximal release stent.Block h10: an ultraflex esophageal proximal release stent and delivery system were received for analysis.Visual inspection found the stent was returned partially deployed.Functional examination was performed by actuating the delivery system (pulled the finger ring with the deployment suture), and the stent was able to fully deploy.No other issues were noted to the stent and delivery system.The reported event of stent was returned partially deployed was confirmed via visual inspection.The investigation concluded that the reported event was most likely due to procedural and/or anatomical factors encountered during the procedure.Additionally, it was reported that the lot number of the device involved during the procedure was used after the expiration date.The device has exceeded the period of time/date recommended by the manufacturer for storing the device without a degradation in quality.Therefore, a review and analysis of all available information indicated the most probable cause is shelf life/expiration date exceeded.A review of the manufacturing documentation for this device revealed that no anomalies or deviations related to the event occurred during manufacturing.Block h11: blocks e1, e2 and e3 have been corrected.
