Abstract

The proposed intravenous filter comprises two cones (1, 2) which are open at the base. The apexes of the cones (1, 2) are connected. The cones (1, 2) are formed by elastic threads (3, 4) with free ends. At least some free ends of the threads (3) of one cone (1) are divided into two sections (5, 6) which are bent in opposite directions in relation to the filter axis (7). The apexes of the cones (1, 2) point towards each other.
