Primary Outcome Measures:
  • Clinical Success [ Time Frame: 6 Months ] [ Designated as safety issue: Yes ]
    Clinical Success is a composite endpoint consisting of technical success with freedom from pulmonary embolism, filter migration and device related events requiring intervention.


Secondary Outcome Measures:
  • Rates of complications related to vena cava filter use. [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
