Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one of ordinary skill in the art that the present invention may be practiced without these specific details. Therefore, the specific details set forth are merely exemplary, and specific details may be varied in the spirit and scope of the invention and still be considered to be within the spirit and scope of the invention.

[0040] The heart valve stent provided in this embodiment can be used on the aortic valve, mitral valve, tricuspid valve or pulmonary valve stent system, and besides the self-expandable stent, it can also be applied to other types of stents, such as balloon expansion , Mechanically expandable valve stents, etc. The heart valve prosthesis provided by the ...

Abstract

The invention discloses a heart valve stent and a prosthesis thereof. The stent comprises a stent frame; the stent frame comprises multiple mutually connected grids; two ends of the stent frame are provided with multiple end grids; at least one end grid is a first end grid; all the end grids at the end, where the first end grid is located, are continuously and completely distributed in the circumferential direction; and the projection height of the first end grid in the axial direction is lower than the projection heights of other end grids at the same end in the axial direction. According to the heart valve stent and the prosthesis thereof provided by the invention, damage to a conduction system can be reduced; conduction retardation can be reduced; the operation safety can be improved; and the life quality of a patient can be improved.

Description

technical field [0001] The invention relates to an interventional medical prosthesis, in particular to a heart valve support and the prosthesis. Background technique [0002] There are four valves in the human heart, including the aortic valve, pulmonary valve, mitral valve and tricuspid valve. They all act as one-way valves. With the rhythmic contraction and relaxation of the heart in the blood circulation, the heart valves also open and close rhythmically, so that the blood can pass through the valve orifice and prevent backflow, so that the blood can flow in the body according to a certain pressure. The direction of circulation flow, in order to maintain the normal function of the circulatory system. When the heart valve is inflamed, it will cause structural damage, fibrosis, adhesion, shortening, myxomatous degeneration, ischemic necrosis, and calcium precipitation; in addition, congenital developmental deformities will also cause valve disease and affect normal It is ...
