Embodiment Construction

[0047] The present invention will be further explained below in conjunction with the accompanying drawings.

[0048] figure 1 It shows that the present invention provides a first embodiment of a pulmonary valve stent, which is L-shaped and includes a valve fixing part 1 , a supporting part 2 and a transition section 3 .

[0049] The transition section 3 , the valve fixing part 1 and the support part 2 are generally integrally constructed and can be obtained by laser engraving.

[0050] The valve fixing part 1 is a cylindrical structure for installing a prosthetic pulmonary valve.

[0051] There is one supporting part 2 in a cylindrical structure, and the supporting part 2 can be placed on the left pulmonary artery or the right pulmonary artery according to the specific conditions of the patient.

[0052] There is also one transition section 3 for connecting the valve fixing part 1 and the support part 2 , and the transition section 3 is overlapped with the connecting part o...

Abstract

The invention discloses a pulmonary artery valve replacement device and a support thereof. The support comprises a valve fixing part, the top edge of the valve fixing part and a support part used for supporting a left pulmonary artery or / and right pulmonary artery are connected through a transitional section, and both the valve fixing part and the support part are of cylindrical structures. The transitional section is provided with a transitional arc surface fittingly contacting with the inner wall of blood vessels. The pulmonary artery valve replacement device comprises a pulmonary artery valve support, an artificial valve is arranged in the valve fixing part, and the valve fixing part is provided with a tectorial membrane below the artificial valve. The pulmonary artery valve support and the pulmonary artery valve replacement device can solve two problems that backflow of pulmonary artery valve and restenosis of pulmonary artery after pulmonary artery valve operation at the same time and are high in stability, operation risk of support displacement is avoided, damage of blood vessels are less prone to causing, stenosis of pulmonary artery branches is solved and repeated implanting of multiple supports is not needed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pulmonary valve replacement device and a bracket thereof. Background technique [0002] Pulmonary valve stenosis usually refers to pulmonary valve or pulmonary valve combined with right ventricular outflow tract stenosis. It can exist alone or be one of the lesions of other complex congenital heart diseases (such as: tetralogy of Fallot). Pulmonary stenosis The incidence rate accounts for 10% to 20% of the total number of congenital heart diseases. According to the different parts of the stenosis, it can be divided into pulmonary valve stenosis, funnel stenosis, and main pulmonary artery and pulmonary artery branch stenosis, among which pulmonary valve stenosis is the most common. The surgical method for pulmonary artery stenosis should be determined according to different lesions. [0003] (1) Pulmonary valve decommissioning: It can be performed under hypothermia or ...
