It was reported that during preparation, a three-way stopcock was attempted to be connected to the port of the copilot bleed back control valve (bbcv); however, a good connection could not be secured, and the stopcock was not connected.There was no patient involvement and no clinically significant delay in the procedure.Returned device analysis identified that fluid was observed leaking from a crack on the middle portion of the rotator distal to the o-ring.No additional information was provided.

The device was returned for analysis.The reported loose or intermittent connection was unable to be confirmed.Additionally, breaks (longitudinal crack on the body of the copilot, a crack on the middle portion of the rotator) and a leak was noted.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history did not indicate a lot specific quality issue.As the reported difficulties were unable to be confirmed during return analysis, it is possible that the device was not fully connected/tightened resulting in the reported loose/intermittent connection; however this cannot be confirmed.The investigation determined a conclusive cause for the reported loose/intermittent connection cannot be determined.The noted breaks (longitudinal crack on the body of the copilot, crack on the middle portion of the rotator) and the noted leak possibly occurred as a result of inadvertent mishandling during attempts to connect the devices and/or during shipment back for return analysis; however this cannot be confirmed.There is no indication of a product quality issue with respect to manufacture, design or labeling.
