Patient's exact age is unknown; however it was reported that the patient was over the age of 18.(b)(4).Investigation results: visual examination of the returned complaint device found that the balloon and the catheter of the device had no damages.Media inspection on the photo provided found a balloon inflated with a pinhole in the distal side.Functional analysis was performed, and the balloon was inflated without a problem; however, the balloon would not hold pressure due to a pinhole located in the distal section on the body of the balloon.It is possible that interaction with the scope or any other surface during the procedure could create friction on the balloon, causing the reported issue of balloon pinhole during the procedure.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.A labeling review was performed and from the information available, this device was used per the instructions for use (ifu)/product label.
