Embodiment Construction

[0030] A transcatheter aortic valve device of the present invention is used to be implanted into the in situ aortic valve caused by aortic valve stenosis, so as to solve the problem of accurate positioning of the aortic valve device; further, Solve problems adapting to multiple conditions such as isolated aortic stenosis or regurgitation.

[0031] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] Such as Figure 1 to Figure 2 The shown aortic valve device 100 is used to be implanted into the in situ aortic valve caused by aortic stenosis, including: a support frame, and a valve leaflet fixed inside the middle part of the support frame 104, and the skirt 102 fixed along the inner periphery of the support frame and fixed with the leaflet. Furthermore, the skirt 102 forms a circle around the support frame and is fixed with sutures; the leaflets 104 are three pieces, which are sewn on the mi...

Abstract

The invention discloses an aortic valve device conveyed by a catheter. The aortic valve device comprises a supporting frame, valve leaflets fixed to the inner side of the middle part of the supporting frame, and skirt rims which are 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 at the upper end of the supporting frame. Three round connecting claws used for loading the supporting frame are arranged at the tail end of the upper horn mouth structure. A tentacle structure expanding outwards and assisting location by clamping a valve ring is arranged at the outer side of the middle part of the supporting frame. A lower horn mouth structure used for reducing pervalvular leakage and expanding outwards 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...
