The thrombosis filter (I, II) of this invention includes a first and a second filtering and holding unit, each unit including a coupling mechanism (41, 42) at its outer extremity in the form of a hook, and a plurality of resilient struts (31, 32) which radiate from a central hub (51, 52) and lie on the surfaces of cones. The units are interconnected by a core shaft (1) which consists of a compression spring and a pair of core wires. |
