FIELD: medical engineering. SUBSTANCE: device has two single-direction filtering members composed of arc-shaped elastic threads one set of ends of which are free and part on circular ways from each other for making contact with internal blood vessel surface. The other set of ends are collected together in fixing bushings connected to each other axial rod. Each fixing member has two thread sets, each set having even number of threads. The first set has centering threads arranged between fixing threads belonging to the other set, which free ends end in fixing members. Axial rod is flexible. Centering thread set is engageable with blood vessel internal surface to the moment the fixing threads open and contact is made between ends of fixing threads and blood vessel surface. EFFECT: reliably retained centered position of fixing members; enhanced effectiveness in catching thrombi. 8 cl, 2 dwg
