Final device investigation found that the device was returned in good visual condition.Upon eval, it was determined that the deep cone seal was torn.The insufflation port and stopcock lever were securely fastened and had sufficient friction to prevent unintended movement.The device was then pressure tested and showed signs of leaking when a test plug was inserted into the device.No lot number was provided, so the device history record could not be reviewed.As each device is inspected prior to release, no conclusion could be made as to what may have caused the reported event.
