Blank fields on this form indicate the information is unknown, unchanged, or unavailable.Summary of event: as reported, during a mechanical thrombectomy procedure, two tuohy-borst large bore clear plastic sidearm adapters leaked normal saline and contrast behind the y-connector.The device was connected to a guiding catheter, and an unknown wire guide and pressure line were used during the procedure.The procedure was completed using another manufacturer's coronary y-connector.The patient did not require any additional procedures due to this occurrence.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.Investigation evaluation: reviews of the complaint history, device history record, manufacturing instructions, and quality control procedures were conducted during the investigation.A visual inspection and functional test of the returned device were also conducted.The device was returned to cook prior to use.A leak test was performed and the tuohy-borst connector leaked out of the back end of the y connector.Cook completed a review of the device history record (dhr).The dhr for the complaint lot recorded one relevant non-conformance for fitting damaged on 2 devices, however, both were scrapped.A database search for complaints on the reported lot found no additional complaints reported from the field.Although this nonconformance is relevant to the reported failure mode, all nonconforming product was scrapped, there are 100% inspections to capture this nonconformance.Adequate inspection activities have been established, there is objective evidence that the dhr was fully executed, and no other lot related complaints that have been received from the field, it was concluded that there is no evidence that non-conforming product exists in house or in field.A review of relevant manufacturing documents was conducted.It was concluded that the device aspect in question was functionally inspected by quality control and no notable gaps in production or processing controls were noted.There is no indication that a design or process related failure mode contributed to the reported event.Sufficient inspection activities are in place to identify this failure mode prior to distribution.Cook has concluded that component failure unrelated to manufacturing or design deficiencies contributed to this incident.The appropriate personnel have been notified and cook will continue to monitor for similar events.Per the quality engineering risk assessment, no further action is required.This report is required by the fda under 21 cfr part 803 and is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement contained herein is intended to be an admission that any cook device is defective or malfunctioned, that a death or serious injury occurred, nor that any cook device caused, contributed to, or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
