Abstract
A thrombosis filter configured for placement within a blood vessel lumen. The thrombosis filter of the present invention includes a body element, a plurality of struts, and a surface treatment. The surface treatment, comprised in part of an anti-proliferative or anti-angiogenic drug, is applied to portions of the thrombosis filter in order to regulate neointimal growth around the thrombosis filter and its anchor elements. The thrombosis filter may further contain a first and a second surface treatment layer. The first surface treatment layer possesses endothelial cell growth enhancing properties, while the second surface treatment layer includes the anti-proliferative or anti-angiogenic drug. The surface treatment may alternatively be applied to a substrate, which in turn is applied to the filter.
