(b)(4).Investigation results: a visual examination of the returned complaint device found that the balloon did not have any visual defects and was in a good condition.The catheter of the device was carefully inspected and no damages were found.Functional evaluation was performed and the balloon was inflated without problem; however, the balloon would not hold pressure due to a pinhole in the proximal section on the body of the balloon.This failure is likely due to factors or conditions related to procedure during the use of the device, such as the manner in which the device was handled, the technique used by the physician during the procedure, and/or the interaction between the scope and device, that could have affected its performance and its intended purpose.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.
