Patient's exact age is unknown; however, it was reported that the patient was over the age of 18.(b)(6).(b)(4).Investigation results: a visual examination of the returned complaint device found that the exit marker was bunched up.A functional examination was performed, the balloon was inflated and a leak was found due to a pinhole located at the distal shoulder of the balloon.This failure is likely due to adverse factors and/or conditions related to the procedure during the use of the device which limited the performance of the device.Therefore, the most probable root cause is cause traced to component failure.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.
