FDA-Cleared Indications

• Prevention of pulmonary embolism by trapping thrombi in the inferior vena cava.
• Use in patients with venous thromboembolism who have a contraindication to anticoagulant therapy.
• Use when anticoagulant therapy is ineffective or cannot adequately prevent thromboembolism.
• Temporary or permanent filtration of the inferior vena cava, according to the clinical need and device labeling.

Clinical Applications

• Inferior vena cava filter placement for patients with acute or recurrent venous thromboembolism who cannot receive anticoagulation.
• Pulmonary embolism prevention when anticoagulation is contraindicated or has not provided adequate protection.
• Placement through the femoral, internal jugular, or brachial venous approach.
• Optional filter placement when later retrieval may be clinically appropriate.
• Permanent inferior vena cava filtration when the filter is not retrieved.

Reported off-label uses

• Pulmonary embolism prevention in selected patients considered to have very high thromboembolic risk despite being able to receive anticoagulation.
• Use as an adjunct during selected high-risk venous or orthopedic procedures when clinicians judge embolic risk to be unusually high.

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 filter is available in configurations for femoral, jugular, and brachial access; the femoral-approach version may include a hook.
• The treating physician must confirm vessel size, access-vessel suitability, and compatibility with the delivery system before placement.
• Filter retrieval should be considered when protection is no longer needed, because prolonged dwell time can make retrieval more difficult and may increase device-related complications.
• MRI safety and conditions depend on the current device labeling and the exact implanted configuration; confirm the manufacturer’s MRI instructions before scanning.
• The device is not a replacement for anticoagulation when anticoagulation is safe and clinically indicated. Placement requires assessment of bleeding risk, clot burden, caval anatomy, and potential contraindications.
