(b)(4).Investigation results: a visual examination of the returned complaint device found that the balloon did not have any visual defects.The inner radio opaque (ro) markers inside the balloon were inspected for any sharp edge but none of them showed abnormalities.Functional analysis was performed, the balloon was leaking due to a pinhole located near the distal section of the ro marker of the balloon.This failure is likely due to factors encountered during the procedure, such as handling of the device, the technique used by the physician, the interaction with the scope, and normal procedural difficulties encountered during the procedure, that could have affected device 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.
