An occlusion device for preventing the passage of blood through an artery or vein
By designing a closure device with a wire structure and a hook structure, the problem of smaller catheters being unable to occlude larger blood vessels in existing technologies has been solved, achieving safe and stable vascular occlusion and rapid blood flow blockage, and reducing the risk of migration.

Abstract
This invention relates to an occlusion device for use in a vascular system to prevent blood from passing through an artery or vein. The object of this invention is to allow the occlusion device to pass through a catheter of a smaller diameter. This object is achieved by an occlusion device (10) for preventing blood from entering an artery or vein, comprising a wire structure (20) and a blood-impermeable membrane (25), the wire structure having a proximal end and a distal end and including a proximal tip (22) and a distal tip (21), and a proximal conical portion (52), a cylindrical portion (51), and a distal conical portion (50) between the tips. The tips (21, 22) contain an even number of wires of more than five, and the wires (20) extend in pairs from the tips (21, 22) along the conical portions (50, 52), and the cylindrical portion (51) is formed by such wire pairs consisting of two wires (20) from adjacent wire pairs of the conical portions (50, 52).
