ABSTRACT:
A thrombosis filter that has an improved filtering function and can be securely anchored at a desired location and be removed through an endovenous route even after the growth of neointima. The thrombosis filter of this invention includes a first and a second filtering and holding unit, each unit including a coupling mechanism at its outer extremity in the form of a hook, and a plurality of resilient struts which include vein wall junction portions that lie parallel to the vein wall and are biased into contact therewith. The preferred embodiment includes picks that impale the vein wall to a limited depth. The units are interconnected by a core shaft which consists of a compression member and a pair of core wires.
