Problems solved by technology

At present, most of the occluders in clinical use contain a disc-shaped structure, which will protrude into the ventricular cavity and affect the structural function of the heart, which limits the scope of application of minimally invasive treatment of ventricular septal defect, such as near the valve, near the chordae, near the conduction bundle and Ventricular septal defect at the outflow tract, due to the risk of the disc-shaped structure of the occluder affecting important structures of the heart, open surgery has to be chosen

Embodiment Construction

[0012] as attached figure 1 As shown, the EY ventricular septal defect occluder has a shape similar to a guide wheel, and the occluder is formed by braiding a plurality of nickel-titanium alloy wires in one piece. The occluder includes a left ventricular surface, a right ventricular surface, an anchoring surface, a steel sleeve and a rivet structure.

[0013] The main body and the rivet are integrally formed, some broken ends of the metal wires are bent on the anchoring surface to form a rivet structure, and the rest are tied and fixed by a steel sleeve on the surface of the left ventricle.

[0014] The nickel-titanium alloy wire is a medical high-elasticity nickel-titanium alloy wire.

[0015] The rivet structure is perpendicular to the anchoring surface on which it is located.

[0016] The preparation method of the invention is as follows: a hollow sphere with a certain diameter and density is prepared from a plurality of high-elastic nickel-titanium alloy wires through a ...

Abstract

The invention relates to an EY ventricular septal defect plugging device. A rivet structure is used for penetrating into cardiac muscle to anchor the device; as a disc-shaped structure is not contained, the implant does not protrude into a ventricular cavity at all after being implanted, and the influence on the heart structure function can be reduced; the shape of the plugging device is specially designed for non-membrane ventricular septal defect plugging treatment, and equipment guarantee is provided for interventional treatment of the type of ventricular septal defect.

Description

technical field [0001] The invention relates to an occluder for medical instruments, in particular to an EY ventricular septal defect occluder. Background technique [0002] Ventricular septal defect is the most common malformation of congenital heart disease, which can exist alone or in combination with other malformations. The incidence of this disease is about 0.2% of surviving neonates, and it accounts for more than 20% of congenital heart disease. This defect can occur anywhere in the ventricular septum. Minimally invasive is the preferred option for treatment. Ventricular septal defect occluder is an essential medical device for this minimally invasive treatment of ventricular septal defect. At present, most of the occluders in clinical application contain a disc-shaped structure, which protrudes into the ventricular cavity and affects the structural function of the heart, which limits the application scope of minimally invasive treatment of ventricular septal defec...
