Investigation ¿ evaluation: reviews of the dimensional verification, complaint history, device history record, instructions for use (ifu), manufacturer¿s instructions, quality control, specifications, and a functional test & visual inspection of the returned device were conducted during the investigation.The visual inspection of the returned package confirmed that the correct complaint device was returned for investigation.Upon further inspection, the device showed droplets of liquid within the balloon but was unable to be further inflated or deflated.The device was then placed in a decontamination mixture.At a later date, the device was removed from the mixture and a functional test was attempted.The balloon was successfully inflated to the rated burst pressure and deflated completely.The balloon was completely deflated in under 60 seconds.After reviewing this information, the returned device does not support the customer¿s original allegations.Additionally, a document based investigation evaluation was performed.There is no evidence to suggest the product was not made to specifications.A review of the device history record did show nonconforming events which could contribute to this failure mode.These nonconformances were noted for leakage.While potentially related to the reported failure mode, it should be noted that the affected units were scrapped and not replaced prior to order completion.It should also be noted there were no other reported complaints for this lot number.Furthermore, reviews of the manufacturer¿s instructions, specifications, and quality control procedures were conducted, and no gaps were discovered.Moreover, product labeling was also assessed.The values and indications on the box packaging were determined to be accurate and descriptive of the device.The instructions for use, provided with this device, indicate to allow adequate time for the balloon to inflate and pull a vacuum with either syringe or inflation device.Based on the information provided and the examination of the returned product, investigation has concluded that a root cause could not be established.Investigation was unable to recreate the reported failure mode during functional testing.We will continue our monitoring of similar complaints and have notified the appropriate personnel of this event.Per the quality engineering risk assessment no further action is required.This report is required by the fda under 21 cfr part 803.This report is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement made in it is intended to be an admission that any cook device is defective or malfunctioned; that a death or serious injury occurred; or that any cook device caused or contributed to; or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
