Manufacturer Narrative

A visual examination of the complaint device revealed that the exit marker was loose.The visual inspection also revealed that the catheter had a kink.A functional examination was not performed because the balloon was relaxed and deflated, which made the device unable to be inserted into a scope.Based on the condition of the returned device, the reported failure of exit marker loose was confirmed.This failure likely occurred because a vacuum was not maintained during insertion through the scope.It is likely that excessive force was used to overcome the resistance experienced during device advancement through the scope, which resulted in the exit marker becoming loose and the catheter to become kinked.The directions for use (dfu) requires that a vacuum is applied to the balloon to maximize endoscopic passage of the balloon through the scope.Therefore, the most probably root cause is user/use error.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.A search of the complaint database revealed that no other complaints exist for the specified lot.
