Venous Thromboembolic Disease
Device: Bard Recovery G2 Filter System

Study Type: Interventional
Study Design: Endpoint Classification: Safety Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: The Bard® Recovery® Filter Registry (EVEREST) for Patients Who Are Candidates for an Optional (Retrievable) Inferior Vena Cava Filter That Undergo Placement of the Bard® Recovery® Filter.

Primary Outcome Measures:
  • Technical Success (Retrieval) [ Time Frame: 1 month post filter retrieval or through 6 months following implantation ] [ Designated as safety issue: No ]
    Technical success for retrieval of the filter such that the entire filter is removed.

  • Clinical Success (Retrieval) [ Time Frame: Time of Retrieval or through 6 months of implantation ] [ Designated as safety issue: Yes ]
    technical success without subsequent damage to the cava wall or other retrieval-related complications requiring intervention.

  • Percentage of Participants With Adverse Events Through 30 Days Post Retrieval [ Time Frame: 30 days post retrieval ] [ Designated as safety issue: Yes ]
    Adverse events occurring at the time of retrieval through 30 days post filter retrieval procedure

Secondary Outcome Measures:
  • Filter Migration > 2cm [ Time Frame: 30 days post retrieval or 6 months following filter placement ] [ Designated as safety issue: Yes ]
    Percentage of subjects experiencing filter migrations from the initial placement position of 2cm or more.

  • Incidence of Filter Fracture [ Time Frame: at 6 months or at retrieval of the filter ] [ Designated as safety issue: Yes ]
    occurrence of fracture assessed at retrieval by the Investigator (broken filter arms, legs, or other components)
