Embodiment Construction

[0034] An aortic valve device delivered through a catheter of the present invention is used to be implanted into the in situ aortic valve caused by aortic valve stenosis or insufficiency, so as to solve the problem of accurate positioning of the aortic valve device and once released The problem of non-recovery; also trying to solve the problem of adapting to multiple conditions, such as severely calcified aortic valve stenosis, isolated aortic valve stenosis or insufficiency, and bicuspid problems.

[0035] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] Such as Figure 1 to Figure 4 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...

Abstract

The invention discloses an aortic valve device conveyed by a catheter. The aortic valve device comprises a supporting frame, wave leaflets and a skirt. The valve leaflets are fixed to the inner side of the middle of the supporting frame. The skirt is fixed along the periphery of the inner side of the supporting frame and fixed to the valve leaflets. An upper horn mouth structure in a three-valve form is formed by the upper end of the supporting frame. Three circular connection jaws used for loads of the supporting frame are arranged at the tail end of the horn mouth structure. Thorn-shaped positioning rods extending towards the bottom end of the supporting frame to be exposed are arranged on the outer side of the middle of the supporting frame. A lower horn mouth structure used for reducing outward expanding of perivalvular leakage is arranged at the bottom end of the supporting 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...
