Detailed Description

The present invention will be more clearly and completely described below with reference to the accompanying drawings.

Example 1

This embodiment discloses an occluding device with spherical connectors, as shown in fig. 1-2, which comprises a mesh body 40, a line of constriction, spherical connectors 60 and a flow-blocking barrier. The structure of the reticular body 40 is similar to that of the prior art, and comprises two net disks, and membranes for endothelial cells to climb are sewed in the two net disks. In this embodiment, the two net disks are both concave and have the same concave direction.

The mesh body 40 has a female end 41 and a connecting end 42 disposed opposite each other. The closing-in lines are arranged on the plurality of grids at the closing-in end 41 to realize closing-in at the closing-in end 41. The spherical connector 60 is connected to the connecting end 42, the spherical connector 60 comprising a sphere having an operating area for connection with a conveyor for transporting the stopper. The barrier layer is located inside the mesh body 40 to block the flow of blood. In this embodiment, the choke barrier is perpendicular to the central axis of the mesh.

In the embodiment, the operation area on the spherical connecting piece can realize the threadless connection with the conveyor, and the processing difficulty and the manufacturing cost are favorably reduced under the condition that threads do not need to be processed.
