A review of the complaint history, specifications, and photographic inspection of the device was conducted during the investigation.The device is shipped with instructions for use (ifu), which advise to avoid use of excessive force.A photograph of the complaint device was provided.According to the photo, the hub had separated from the blue sheath.The sheath flaring appears intact.The flare appears to be properly shaped and sized in the photo; however, without return of the complaint device, the actual flare dimension and through hole of the connector cap cannot be measured.Also, the black catheter of the retrieval loop system is placed inside the blue sheath and the separated hub is placed next to it.Therefore, it is probable that excessive force during the filter retrieval procedure caused the hub to separate from the sheath, and that the catheter was removed and replaced inside the blue sheath after the separation.However, based on the information provided, no product returned, and the results of our investigation; a definitive root cause could not be determined.Per the risk assessment, no further action is warranted.Monitoring will continue to be performed for similar complaints.
