Embodiment 1
[0029] The atrial shunt of the present invention, the whole shunt is woven into a net by NiTi wire with memory function and super elasticity, and the two ends of the shunt are ligated by a steel sleeve and then heat-shaped. The shunt has good flexibility and can pass through the sheath. delivery. Such as figure 1 , figure 2 As shown, the diverter includes a right disk surface 1, a left disk surface 2 and a shorter waist 3, and the right disk surface 1 and the left disk surface 2 are parallel to each other. In the center of the two disk surfaces, there is a circular middle through hole c that penetrates the left and right disk surfaces (i.e., the right disk surface 1, the left disk surface 2) and the waist 3 (the two ends of the middle through hole c are the mesh ports 11 on the right disk surface and the left disk surface Net opening 21), the diameter of the waist 3 of the present invention is larger than the diameter of the middle through hole c on the right disk surface 1 an...
Embodiment 2
[0037] In this embodiment, such as image 3 As shown, one of the right disk surface 1 and the left disk surface 2 is inclined inward to form an included angle, which increases the firmness of the shunt on the atrial septum.
[0038] Others are the same as in Example 1.
Embodiment 3
[0040] In this embodiment, such as Figure 4 As shown, the right disc surface 1 and the left disc surface 2 are both inclined inward to form an included angle and clamp each other to increase the firmness of fixing the shunt on the interatrial septum.
[0041] Others are the same as in Example 1.
