Embodiment 1

[0036] The upper end of the support frame 1 is provided with an upper positioning body 5 with a preset shape, and the lower end of the support frame 1 is provided with a lower positioning body 6 with a preset shape.

[0037] The combination of the side positioning body 2, the upper positioning body 5 and the lower positioning body 6 forms a balloon 11 with an integrated structure. The balloon 11 includes an opening. The support frame 1 is arranged at the opening of the balloon 11. The support frame 1 and the ball A sealed cavity 12 is formed between the inner sides of the balloon 11, and the support frame 1 is provided with a pipeline 13 for the cavity 12 to enter or flow out fluid; the envelope structure of the balloon 11 covering the stent frame 1 is adopted to achieve The effect of facilitating the positioning and use of the heart defect occluder.

[0038] When in use: 1. The side positioning body 2, the upper positioning body 5 and the lower positioning body 6 can communicate w...

Embodiment 2

[0041] The upper end of the support frame 1 is provided with an upper positioning body 5, and the lower end of the support frame 1 is provided with a lower positioning body 6. The upper positioning body 5 and the lower positioning body 6 are both inflatable bodies (similar to balloons) that can be expanded and expanded outwardly when filled with fluid. The body is distributed on the circumferential wall of the support frame in an annular shape. When the expansion body is filled with fluid, the expansion body begins to expand outward and expand.

[0042] An upper duct 3 communicating with the upper positioning body 5 and a lower duct 4 communicating with the lower positioning body 6 are provided in the pocket 7 of the support frame 1, so as to inject fluid into the upper positioning body 5 and the lower positioning body 6 respectively. Force it to expand or splay outward.

[0043] One end of the upper duct 3 is connected to the upper positioning body 5, and the other end is filled w...

Embodiment 3

[0046] A cardiac defect occluder includes a support frame 1, a side positioning body 2, an upper positioning body 5, a lower catheter 4 and a lower positioning body 6.

[0047] The side part of the support frame 1 is provided with a side positioning body 2, the middle of the support frame 1 is provided with a receiving groove 7, and the bottom end of the receiving groove 7 is open, and the receiving groove 7 of the support frame 1 is connected with the side positioning body 2 The side duct 8 is used to inject fluid into the side positioning body 2 to force it to expand toward or expand outward.

[0048] In a preferred embodiment, one end of the side pipe 8 is connected to the side positioning body 2, and the other end is filled with a rubber plug 9.

[0049] The upper end of the support frame 1 is provided with an upper positioning body 5, which is connected to the side positioning body 2. The upper positioning body 5 is an expansion body (similar to a balloon) that can be expanded a...

Abstract

The invention provides a heart defect occluder comprising a supporting frame and a side locating body arranged on the side of the supporting frame. The supporting frame is provided with an accommodating groove in the middle; the bottom end of the accommodating groove is open; the accommodating groove of the supporting frame is provided with a side catheter communicating with the side locating body; the side catheter is used for injecting fluid into the side locating body to force the side locating body to expand outward or stretch outward. The side of the supporting body is provided with the side locating body; during use, after scanning a heart defect part of a patient with an instrument, a support can be formed through a 3D printing die making and the side locating body can be mounted on the support; through inflation or fluid injection, the radial size of the heart defect occlude can be changed, so that the heart defect occlude can best fit the defect part of the patient.

Description

Technical field [0001] The present invention relates to a medical heart defect occluder, in particular to a new type of cardiac septal defect occluder which is suitable for minimally invasive occlusion surgery and has convenient and quick operation and safer use, which can be used to repair oval Patent foramen (PFO), atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA). Background technique [0002] Congenital heart disease includes patent ductus arteriosus (PDA), patent foramen ovale (PFO), atrial septal defect (ASD) and ventricular septal defect (VSD). PDA can cause blood to flow between the aorta and pulmonary artery. PFO and ASD can cause blood to flow between the left and right atrium. VSD can cause blood to flow between the left and right ventricles. When there is a lot of traffic, it usually needs to be repaired. Since the 1970s, the interventional therapy of occluding the defect of the heart through the heart defect occluder h...
