(b)(4).Block h10: a wallflex duodenal delivery system was received for analysis; the stent was not returned.Visual examination of the returned device found the stainless steel tube, and the outer sheath at 3 inches from the exterior tube handle were kinked.No other issues with the delivery system were noted.The noted damages on the returned device are consistent with excessive force applied during use.The investigation concluded that procedural factors as handling of the device, or the technique used by the physician, and normal procedural difficulties encountered during the procedure, could have affected the device performance and its integrity contributing to the failure reported.Therefore, the most probable root cause is adverse event related to procedure.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications at the time of release for distribution.This supplemental correction report is being filed to correct the report number in a previously submitted supplemental report (follow-up number 001) which was accepted by fda on 12/26/2018 12:30 pm ct.The report number is being corrected from: 3005099803-2018-62167 to: 3005099803-2018-61514.
