Information provided by (Responsible Party):
C. R. Bard
ClinicalTrials.gov Identifier:
NCT00556426
First received: November 8, 2007
Last updated: May 25, 2012
Last verified: May 2012
  Purpose
This study was designed to assess the safety of retrieval of the Bard Recovery® G2® Filter System. The G2 filter is an FDA-cleared device for inferior vena caval interruption in patients with pulmonary thromboembolism.

Condition Intervention
Pulmonary Embolism Venous Thromboembolic Disease Device: Bard Recovery G2 Filter System

Study Type: Interventional
Study Design: 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.

Further study details as provided by C. R. Bard:

Primary Outcome Measures:
  • Technical Success (Retrieval) [ Time Frame: 1 month post filter retrieval or through 6 months following implantation ]
    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 ]
    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 ]
    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 ]
    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 ]
    occurrence of fracture assessed at retrieval by the Investigator (broken filter arms, legs, or other components)
