Block e1: initial reporter address 1: (b)(6).Block h6: imdrf device code a150103 captures the reportable event of stent prematurely deployed outside patient.Block h10: a wallstent colonic delivery system was received for analysis; the stent was not returned.Visual examination of the returned device did not find any damages or issues to the delivery system.The reported event of stent prematurely deployed could not be confirmed; this problem occurred during the procedure, and it is not possible to replicate in the laboratory of analysis.The investigation concluded that the reported event was most likely due to procedural factors, such as lesion characteristics, handling and manipulation of the device.The technique used by the user, and/or normal procedural difficulties encountered during the procedure, limited the performance of the device and contributed to premature deployment of the stent.Therefore, a review and analysis of all available information indicated the most probable cause is adverse event related to procedure.A product labeling review identified that the device was used per the directions for use (dfu) / product label.
