[0032] Example one
[0033] figure 1 It is a schematic diagram of the structure of the first atrial septal hole stent of the present invention, figure 2 for figure 1 The structure diagram of the stent shown after expansion. figure 1 with figure 2 The bracket 10 shown includes a columnar main unit section 1, two columnar auxiliary unit sections 2 and a connecting rod 3.
[0034] Two columnar auxiliary unit sections 2 are respectively located on both sides of the support 10 in the axial direction, and a number of rods 21 arranged end to end in a wave shape surround the cylindrical surface of each auxiliary unit section 2 in the arrangement direction. The wave width and wave height of the cylindrical wave of each sub-unit section 2 are the same. In other applications, the wave width and wave height of the cylindrical wave of each subunit section 2 may also be different.
[0035] A columnar main unit section 1 is located in the middle of the stent 10 along the axial direction, and sev...
