Block h6: device code a1401 captures the reportable event of balloon failed to deflate.Block h10: investigation results: a visual examination of the returned complaint device found that the catheter was detached in two sections.It was also noted that the catheter was kinked and the balloon was not returned with the device.Microscopic analysis was performed, and it was confirmed that the catheter was cut.The reported event of balloon failed to deflate was confirmed based on the found failure of catheter kinked which probably affected the deflation time thus, the device had to be cut.This failure is likely due to factors encountered during the procedure, such as the interaction between the device with the scope, and normal procedural difficulties encountered during the procedure could have possibly affected the device performance and its intended purpose.Therefore, the most probable root cause is adverse event related to procedure and the device had no influence on event.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.
