Gunther Tulip Vena Cava Filter Set for Femoral Vein Approach Gunther Tulip Vena Cava Filter Set for Femoral and Jugular Vein Approach

FDA-Cleared Indications

• Use in patients at risk for pulmonary embolism when protection from venous thromboembolism is clinically indicated.
• Use when anticoagulation is contraindicated, not tolerated, or ineffective.
• Placement through either a femoral vein or jugular vein approach.

Clinical Applications

• Inferior vena cava filter placement for prevention of pulmonary embolism in selected patients with venous thromboembolism.
• Temporary filter placement when anticoagulation cannot be used or must be interrupted.
• Filter placement in patients with recurrent thromboembolic events despite anticoagulation.
• Retrieval of the filter when protection is no longer clinically needed and removal is feasible.

Reported off-label uses

• Use for selected patients without documented venous thromboembolism but considered at unusually high risk of pulmonary embolism.
• Placement in an atypical venous location when standard inferior vena cava placement is not feasible.

Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Practical Considerations

• The system is designed for delivery through either the femoral or jugular venous approach; the appropriate access route depends on anatomy, thrombus location, and the planned filter position.
• Available filter and delivery-system sizes should be matched to the patient's inferior vena cava diameter and the specific product instructions for use.
• Placement and retrieval are performed under imaging guidance, commonly fluoroscopy, with venography or other imaging used to assess anatomy and thrombus.
• Potential complications include access-site bleeding, filter migration, tilt, fracture, perforation of the vena cava, thrombosis, and difficulty or inability to retrieve the filter.
• MRI conditions and scan limits should be confirmed in the current manufacturer labeling before MRI. The device should not be assumed to be MR safe without reviewing its MR status.
