Title:
FILTER
Document Type and Number:
WIPO Patent Application WO/2018/099147
Kind Code:
A1
Abstract:
Disclosed is a filter (10), the filter comprising a distal filter (13), a proximal filter (14), a connecting rod (15) for connecting the distal filter (13) and the proximal filter (14), and at least one support rod connected to the connecting rod (15) and located on the outside of the connecting rod (15). The radial sectional area of a portion of the connecting rod (15) is less than the radial sectional area of other portions of the connecting rod (15). The distal filter (13) comprises a plurality of distal filter rods (131). One end of each of the distal filter rods (131) is connected to the connecting rod (15), and the other end of all distal filter rods (131) converge to the distal end (11). The radial sectional area of a portion of a flexible segment provided on the connecting rod (15) of the filter is less than the radial sectional area of the rest of the connecting rod, thus achieving the effect of changing and increasing the local deflection of the connecting rod (15). Where the filter (10) is subjected to radial pressure from a lumen wall, the flexible segment of the connecting rod bends toward the interior of the filter so that the connecting rod (15) faces away from a blood vessel wall, thus reducing the risk that the connecting rod is covered by epidermal cells and allowing the filter to be more easily removed.
