Embodiment 1
[0046] In the following, the present invention will be further explained by taking the pulmonary artery stent as an example in conjunction with the accompanying drawings.
[0047] Such as figure 1 , figure 2 As shown, the pulmonary artery stent with reduced compressed length includes a supporting grid and an inflow section 5 and an outflow section 1 respectively connected to the axial ends of the supporting grid, and one section of the supporting grid is a transition section 3 .
[0048] One end of the transition section 3 is connected to the inflow section 5 through the mesh section 13, and the other end of the transition section 3 is connected to the outflow section 1 through the mesh section 2, and the mesh section 2, the mesh section 13 and the transition section 3 together form a supporting network frame . Grid segment 2 is composed of continuous rhombus, grid segment 13 is composed of continuous semi-rhombic, inflow segment 5 expands radially outward to form flare com...
Embodiment 2
[0052] In addition to having the same structure of the transition section 3 as in Embodiment 1, this embodiment eliminates isolated end nodes in the pulmonary artery stent.
[0053] Such as image 3 As shown, the radial expansion of the inflow section 5 and the outflow section 1 is flaring. When released in the human body, the outflow section 1 of the pulmonary artery stent is the first release end, and the outflow section 1 is connected to all end nodes 4 on the corresponding side of the support grid. connected. image 3 In the figure, the posterior half of the pulmonary artery stent is omitted, and only the anterior half of the pulmonary artery stent is shown.
[0054] The outer edge of the outflow section 1 is surrounded by a number of curved support bars 6, and each adjacent four end nodes 4 are taken as a group, and in a group of end nodes 4, there is one support bar 6 and two connecting bars 8 , the two ends of the support bar 6 are respectively connected to the two en...
Embodiment 3
[0057] In the following, the present invention will be further explained by taking the aortic stent as an example in conjunction with the accompanying drawings.
[0058] Such as Figure 4 As shown, the aortic stent with reduced compressed length includes a support network frame and an outflow section 15 and an inflow section 10 connected to both axial ends of the support network frame, and one section of the support network frame is a transition section 11 .
[0059] One end of the transition section is connected to the outflow section 15 through the mesh section 9, and the other end of the transition section 11 is connected to the outflow section 10 through the mesh section 14, and the mesh section 14, the mesh section 9 and the transition section 11 together form a supporting grid. The mesh section 14 and the mesh section 9 are composed of continuous semi-rhombic shapes. Compared with the transition section 11, the inflow section 10 expands outward in the radial direction to...
