(b)(4).Visual examination of the returned complaint device found the balloon did not show visual defects and was in a good condition.There were also blood residues noticed inside the balloon.No damage was found on the catheter of the device.Functional analysis was performed, and the balloon was inflated without a problem; however, the balloon would not hold pressure due to pinholes in the body of the balloon over the ro markers in the proximal sections, thereby confirming the reported event of balloon leak.This failure is likely due to factors or conditions related to the procedure during the use of the device, such as the manner in which the device was handled and manipulated, 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.A labeling review was performed and from the information available, this device was used per the instructions for use (ifu)/product label.
