Manufacturer Narrative

Block h6: patient code e1006 captures the reportable event of intestinal bleeding.Block h10: a wallstent enteral delivery system was received for analysis.The stent was not returned.During visual inspection, the delivery system was inspected and no problems were noted.The reported event of perforation, bowel could not be confirmed as this occurred during the procedure.A product labeling review identified that the device was used per the instructions for use (ifu) / product label.Additionally, perforation is noted within the ifu as a potential complication associated with the use of the device.Based on the available information, there is not enough evidence to establish the cause of the reported event as the stent was not returned for analysis.The investigation concluded that, without proper evaluation of the device, there is a lack of objective evidence or descriptive conditions of the event required to determine a probable cause of the event.
