Embodiment Construction

[0032] The object of the present invention is a transcatheter aortic valve device for implantation into the in situ aortic valve caused by aortic stenosis or insufficiency or regurgitation to solve the problem of positioning of the aortic valve device Accurate and not retrievable once released; also trying to solve the problem of adapting to multiple conditions, such as isolated aortic stenosis or regurgitation.

[0033] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Such as Figure 1 to Figure 2 The shown aortic valve device 100 is used for implanting into the in situ aortic valve caused by stenosis or insufficiency of the aortic valve, comprising: a support frame fixed inside the middle part of the support frame leaflet 104, and a skirt 102 fixed along the inner periphery of the support frame and fixed to the leaflet. Furthermore, the skirt 102 forms a circle around the support frame and is fix...

Abstract

The invention discloses an aortic valve membrane device conveyed through a catheter. The aortic valve membrane device comprises a support frame, valve leaflets fixed on the inner side of the middle of the support frame and skirt edges which are fixed in the periphery of the inner side of the support frame and fixed with the valve leaflets, wherein the upper end of the support frame is of a three-valve type upper horn mouth structure, three circular connecting claws used for loading of the support frame are arranged at the tail end of the upper horn mouth structure, exposed circular-arc-shaped positioning rods which extend in the bottom end direction of the support frame are arranged on the outer side of the middle of the support frame, and a lower horn mouth structure used for reducing outward expansion of perivalvular leakage is arranged at the bottom end of the support frame.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an aortic valve device delivered through a catheter. Background technique [0002] With the aggravation of population aging, senile valvular disease and valvular disease caused by coronary heart disease and myocardial infarction are becoming more and more common. Surgery, that is, artificial heart valve replacement or valvuloplasty, is the radical cure for valvular heart disease. However, for some patients who are elderly, have multiple comorbidities, or have a history of surgical thoracotomy, the mortality rate of surgical thoracotomy is very high. high. In recent years, with the progress of interventional therapy technology, the epoch-making technology of transcatheter artificial valve has pushed interventional surgery to the technical peak, and tried to solve all the shortcomings of surgical valve replacement. In 2002, the success of the first transcatheter artificial valve re...
