Problems solved by technology

[0005] To sum up, the defect of the prior art is that when the existing occluder is used for the treatment of atrial septal defect, ventricular septal defect, and patent ductus arteriosus, it cannot effectively relieve pulmonary artery obstruction due to completely blocking the defect or reserving a two-way channel. Hypertension, with associated complications

Embodiment 1

[0043] An atrial septal defect occluder for relieving pulmonary hypertension, comprising an occluding part 1 and a shunt part 2, the shunt part 2 is embedded in the axial center of the occluding part 1 and runs through the occluding part 1, and the part of the occluding part 1 The main body is a mesh structure, and the periphery is coated with a layer of polymer elastic film, and the shunt part 2 is installed in the axial direction with a one-way valve 202 for one-way conduction and conduction;

[0044] The blocking part 1 includes blocking disks 101 at both ends and a waist portion 102 connected in the middle, and the specifications of the blocking disks 102 at both ends are the same or different.

[0045] Based on the above-mentioned atrial septal defect occluder for relieving pulmonary hypertension;

[0046] The system-pulmonary artery shunt can be adjusted to make a large defect into a smaller defect, reducing the system-pulmonary shunt and reducing the capacity overload o...

Embodiment 2

[0048] A ventricular septal defect occluder for relieving pulmonary hypertension, comprising an occluding part 1 and a shunt part 2, the shunt part 2 is embedded in the axial center of the occluding part 1 and runs through the occluding part 1, and the part of the occluding part 1 The main body is a mesh structure, and the periphery is coated with a layer of polymer elastic film, and the shunt part 2 is installed in the axial direction with a one-way valve 202 for one-way conduction and conduction;

[0049] The blocking part 1 includes blocking disks 101 at both ends and a waist 102 connected in the middle.

[0050] After installation, it can effectively alleviate the pulmonary hypertension caused by congenital heart disease ventricular septal defect; after the occluder is installed, it forms a one-way channel that prevents left-to-right shunt and only allows right-to-left shunt, which is convenient for eliminating the volume overload of pulmonary vessels and Pressure conducti...

Embodiment 3

[0052] A patent ductus arteriosus occluder for relieving pulmonary hypertension, comprising an occluding part 1 and a shunt part 2, the shunt part 2 is embedded in the axial center of the occluding part 1 and runs through the occluding part 1, and the occluding part 1 The main body of the shunt is a mesh structure, and the periphery is coated with a layer of polymer elastic film, and the shunt part 2 is installed in the axial direction with a one-way valve 202 for one-way conduction and conduction;

[0053] The blocking part includes blocking disks at two ends and a waist connected in the middle, and the blocking disk is located on one side of the waist, which is a single-side blocking disk structure.

[0054] After installation, it can effectively relieve the pulmonary hypertension caused by patent ductus arteriosus of congenital heart disease; after the occluder is installed, a one-way channel that prevents left-to-right shunt and only allows right-to-left shunt is formed, wh...

Abstract

The invention discloses an occlusion device used for alleviating the pulmonary arterial hypertension of congenital heart disease, and particularly relates to the technical field of medical apparatus and instruments. The occlusion device used for alleviating the pulmonary arterial hypertension comprises an occlusion part and a shunting part, wherein the shunting part is embedded in the axial centerposition of the occlusion part and penetrates through the occlusion part; the main body of the occlusion part is of a reticulate structure, and the periphery of the occlusion part is coated with a layer of high molecular elastic film; and a one-way valve capable of achieving one-way conduction is installed in the axial direction of the shunting part. After the occlusion device is installed, a one-way channel which prevents left-to-right shunting and only permits right-to-left shunting is formed so as to facilitating eliminating of the volume overload of pulmonary vessels and pressure conduction, further injury of pulmonary vessels is lightened, and meanwhile, right-to-left shunting is kept to prevent a serious consequence since pulmonary arterial pressure suddenly rises. The occlusion device is favorable for alleviating the pulmonary arterial hypertension of the congenital heart disease and is suitable to be prompted and used in medical organizations.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an occluder for relieving congenital heart disease pulmonary hypertension. Background technique [0002] Congenital heart disease is the most common type of congenital malformations, accounting for about 28% of various congenital malformations. The channel that should be automatically closed later fails to close (it is normal in the fetus). The incidence of congenital heart disease cannot be underestimated, accounting for 0.4%-1% of live babies, which means that there are 150,000 to 200,000 new congenital heart disease patients in my country every year. The spectrum of congenital heart disease is very wide, including hundreds of specific types. Some patients can combine multiple deformities at the same time. . According to hemodynamics combined with pathophysiological changes, congenital heart disease can be divided into cyanotic or non-cyanotic, and can also be divide...
