Clinically proven to handle most filter replacement situations, the Simon Nitinol Filter^® is versatile and dependable. Simon Nitinol Filter^® offers a wide choice of entry sites, advanced engineering, and the Simon Nitinol Filter/SL^® delivery system that enhances maneuverability and placement accuracy.

Broad Range of Entry Sites

• Simon Nitinol Filter^® offers the widest choice of entry sites of any available filter: right and left femoral, right and left jugular, right and left subclavian, and right and left antecubital.
• A broad range of entry sites means greater adaptability to clinical circumstances and user preferences.

Intelligent Engineering

• Filter material and design permit smooth passage through tortuous vessels.
• The two-level design effectively traps large and small emboli without significant disruption of blood flow
• First level is a proven cone-shaped design.
• Second level self-centers the filter and captures smaller clots.
• Simon Nitinol Filter^® is non-ferromagnetic and will not interfere with MRI.

Versatility

• Simon Nitinol Filter^® adapts to a wide range of caval sizes.
• Featuring a maximum diameter of 28 mm, Simon Nitinol Filter^® has no contraindications for smaller diameters.
• Simon Nitinol Filter^® is designed to meet the sizing needs in 97 percent of patients.

Adaptability

• Simon Nitinol Filter^® accommodates one of the smallest entry points.
• 7F I.D. percutaneous delivery system minimizes entry site complications.
• While other filter introducers require substantially larger puncture holes, with O.D.’s ranging to 15 F, the Simon Nitinol Filter^® allows for a 40 percent size reduction over leading competitors.

Maneuverability and Accuracy

• The Simon Nitinol Filter/SL^® delivery system is simple to deploy and features a streamlined pusher wire handle for greater maneuverability and more accurate placement.
• Unique two-stage femoral deployment option facilitates precise placement.

Proven Clinical Experience

• Simon Nitinol Filter^® represents the first nitinol filter on the market.
• For over ten years hospitals worldwide have used Simon Nitinol Filter^® with confidence.
• More than 85,000 patients have been successfully treated.
• For patients at risk of recurrent pulmonary embolism (PE), including those who cannot tolerate anticoagulant treatment, Simon Nitinol Filter^® can provide an important clinical safeguard.
• Simon Nitinol Filter^® provides an excellent balance between prevention of PE and IVC patency.
