Occupation: non-healthcare professional.Investigation evaluation: the user provided a picture, the device and the deployed clip are inside the open pouch.The clip was open and has been deployed from the device.The lot number in the picture matches the returned pouch.Our laboratory evaluation of the product said to be involved confirmed the report.The device and deployed clip were both returned.During a functional test, the drive wire moved freely inside the outer sheath when the handle was manipulated.A visual examination of the drive wire hook, and catheter attachment showed no deformities or signs of damage.The tabs on the coil catheter (distal end device components) were bent inward at an angle.It is uncertain how this damage could have occurred.A product discrepancy or anomaly that could have contributed to the reported occurrence was not observed.The device history record for the lot number said to be involved was reviewed.A discrepancy or anomaly was not observed with the product that was released for distribution.Investigation conclusion: a definitive cause for this observation could not be determined because the actual use conditions could not be duplicated in the laboratory setting.The instructions for use state: "uncoil device.Verify smooth handle operation and clip action.Open clip by gently moving handle spool distally (away from handle thumb ring).Once clip is fully open, do not continue advancing handle spool as clip may prematurely detach from catheter.Close clip by moving handle spool proximally until clip is fully closed.Caution: do not continue to pull handle spool beyond tactile resistance as this may prematurely deploy clip." the instructions for use states the following precautions: "exercising handle while clip is coiled may result in damage to clip." the instructions for use further states: "caution: do not continue to pull handle spool beyond tactile resistance as this may prematurely deploy clip." prior to distribution, all instinct endoscopic hemoclips are subjected to a visual inspection and functional testing to ensure device integrity.A review of the device history record for the lot number confirmed that the lot said to be involved met all manufacturing requirements prior to shipment.Corrective action: a review of the complaint history was conducted.The likelihood of occurrence is considered rare.Corrective action is not warranted at this time based on the quality engineering risk assessment.Quality assurance will continue to monitor for complaint trends and reassess the risk assessment results as post market feedback continues to become available.
