Manufacturer Narrative
|
An ultraflex esophageal ng stent was received; the device was received with the stent partially deployed.The distal stent loops were deployed and the distal end of the deployment suture was detached from the silastic tubing.Analysis determined that the condition of the returned device was consistent with the complaint incident.No issues were noted with the profile of the remaining crocheted section of the stent or of the delivery device.Given the event description and the condition of the returned device, the noted issues were likely caused by handling of the device or portion of the device without direct patient contact either during unpacking, preparation, or shipping; at the end of the procedure; or when packaging for return.Therefore, the most probable root cause is handling damage.A review of the device labeling and directions for use (dfu) was performed and no anomalies were noted.
