Heart ventricular septal defect plugging device with two flat end faces and manufacturing method of heart ventricular septal defect plugging device

Abstract

The invention discloses a heart ventricular septal defect plugging device with two flat end faces and a manufacturing method of the heart ventricular septal defect plugging device. The heart ventricular septal defect plugging device comprises a main body component , a flow blocking component and a suture line; the main body component is of a net body structure and comprises a first disc-shaped part, a tubular part and a second disc-shaped part which are connected in sequence, and the two ends of the tubular part are connected to the center of the first disc-shaped part and the center of the second disc-shaped part respectively; the flow blocking component is at least two layers of degradable films or non-degradable films for blocking blood flow; after being closed up by the suture line, the outer net surfaces of the first disc-shaped part and the second disc-shaped part are continuous and flat net-shaped surfaces; the heart ventricular septal defect plugging device is made of a special mold. The special mold comprises a core mold; the core mold comprises a first cover body, a central component, a second cover body and a peripheral component. The special mold is used for shaping, so that simpleness, quickness and low cost are realized. The two end faces of the device are smooth, so that the endothelialization process of the surface of the plugging device is accelerated, and a heart ventricular septal defect is repaired by the tissue itself earlier.

Description

technical field [0001] The invention relates to the field of occluders, in particular to a cardiac ventricular septal defect occluder with flat ends and a manufacturing method thereof. Background technique [0002] Ventricular septal defect is one of the common congenital heart diseases. The human heart is composed of four chambers (left atrium, left ventricle, right atrium and right ventricle), there should be a complete interventricular septum between the left ventricle and the right ventricle, if there is an opening in the interventricular septum It's called a ventricular septal defect. Ventricular septal defect is mainly formed during the growth and development of the fetus. Due to some factors affecting the development of the heart, a ventricular septal defect is formed. For patients with ventricular septal defect, blood usually flows from the left ventricle through the ventricular septal defect into the right ventricle, increasing the blood volume of the right ventri...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to solve the problem of long-term risk in the existing clinically used ventricular septal defect occluder, and to overcome the high cost and the protruding connection points on both ends of the occluder in the prior art. Based on the defects of slow endothelialization on the surface of the device and long release length of the occluder, a cardiac ventricular septal defect occluder with flat ends and a manufacturing method thereof are provided
