摘要： An occlusion device comprises a distal end, a proximal end and an elastic braided body which is provided between the proximal end and the distal end and made of wires. The elastic braided body is composed of a multi-stage braided net, which comprises at least a first-stage braided net that is closest to the distal end and made of a plurality of first-stage wires, and a second-stage braided net which is braided by a plurality of first-stage wires and second-stage wires all together. The minimum cross-section area of the first-stage braided net after being compressed toward the direction perpendicular to an axis of the elastic braided body is less than the minimum cross-section area of any other-stage braided net after being compressed toward the axis. A method for manufacturing the occlusion device is also provided.

摘要： An occlusion device has a right disc made from a metal mesh having a plurality of openings, and a left disc having at least two skeletons that are covered by a membrane. Each skeleton passes through openings of the metal mesh to interlock the right and left discs, and a coil is wrapped around each opposing end segment of the skeletons. The skeletons can have a looped section where the skeleton is twisted or looped to cross or overlap itself. In addition, each skeleton can be formed from a braided strand of a plurality of wires.
