Gunther Tulip Vena Cava Mreye Filter Set

FDA-Cleared Indications

• Prevention of recurrent pulmonary embolism in patients at high risk for pulmonary embolism.
• Use in patients for whom anticoagulant therapy is contraindicated.
• Use in patients for whom anticoagulant therapy has failed.

Clinical Applications

• Placement in the inferior vena cava to prevent recurrent pulmonary embolism.
• Temporary protection from pulmonary embolism when anticoagulation cannot be used.
• Protection from pulmonary embolism when pulmonary emboli occur despite anticoagulant therapy.
• Fluoroscopic placement and, when clinically appropriate, retrieval using catheter-based techniques.

Reported off-label uses

• Prophylactic placement in selected trauma or surgical patients who do not have documented pulmonary embolism but are considered at high risk.
• Use in selected patients with venous thromboembolism when anticoagulation is feasible but considered insufficient by the treating team.

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 delivered through a catheter and positioned in the inferior vena cava under fluoroscopic imaging.
• Available filter and delivery-system sizes must be matched to the patient's IVC diameter and anatomy.
• The device is designed for catheter-based placement and retrieval; clinicians should be trained in both techniques.
• MRI safety and conditions depend on the specific device labeling and the implanted filter configuration; verify the current manufacturer instructions before MRI.
• Contraindications and precautions include unsuitable IVC anatomy, venous access problems, active infection at the access site, and inability to safely perform the procedure.
