Embodiment Construction

[0023] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] according to figure 1 Shown, as an example, is a pulmonary artery interventional valve stent. The arc-shaped sheet whose radian is π / 3 is taken, and the material of the arc-shaped sheet is memory metal material. The arc-shaped sheet is cut and engraved with a laser, so that the arc-shaped sheet has a diamond-shaped hollow shape to obtain the support net 1 . Rhombus cell 101 is a single layer. Such as figure 2 As shown, the metal wire 2 is taken, the metal wire is arc-shaped, the two ends...

Abstract

The invention provides a pulmonary artery interventional valve stent and a manufacturing method of a pulmonary artery interventional valve. The pulmonary artery interventional valve stent comprises three arc-shaped supporting nets and three arc-shaped metal wires, wherein the supporting nets and the metal wires are arranged alternatively and are connected in an annular mode. By arranging the novel valve stent, a formed interventional valve is simple to process, the production cost is low, a polyurethane surface layer is formed on the surface of the stent, the stent is not in contact with blood, an anti-thrombus effect is good, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of heart valves, in particular to a pulmonary artery interventional valve support and a preparation method for a pulmonary artery interventional valve. Background technique [0002] The pulmonary valve replacement device in the prior art is composed of a mesh stent made of a memory metal material and a unidirectionally openable trileaf valve sewn in the stent. However, the existing pulmonary valve replacement device has the disadvantages of high cost, poor adaptability and complicated preparation. Contents of the invention [0003] In view of the above-mentioned defects and problems of the prior art, the purpose of the embodiment of the present invention is to provide a pulmonary artery interventional valve stent and a preparation method of the pulmonary artery interventional valve. [0004] In order to achieve the above object, the present invention provides the following technical solutions: [0005] T...
