Greenfield^® RP Vena Cava Filter

Every year, about 200,000 people in the U.S. alone die from pulmonary embolism (PE). This condition is a result of blood clots that form in the legs (known as deep vein thrombosis) that travel up through the heart and lodge in the lungs.

The Greenfield^® Vena Cava Filter is a cone-shaped permanent implant designed to prevent PE by capturing and dissolving this embolized clot. Physicians recognize the Greenfield filter design as the gold standard in patient protection, with 30 years of proven clinical performance. The Greenfield RP Vena Cava Filter, currently in final development, will downsize the delivery system while maintaining long-term clinical efficacy.

In the U.S., where most filters are used, all currently available designs are for permanent implantation. A second filter development effort now underway is designed to offer the advantage of removability. This technological advancement will broaden the range of patients that could benefit from the life-saving protection of a Vena Cava Filter.
