Embodiment Construction

[0031] In order to make the present invention more obvious and understandable, the preferred embodiments are described in detail as follows in conjunction with the accompanying drawings:

[0032] Such as Figure 1-3 As shown, the present invention provides a percutaneous transcatheter mitral valve replacement system, comprising a valve frame support body 1, artificial valve leaflets 2 and an interventricular septal anchoring structure 3; a valve frame support body 1 is provided between the atrium and the ventricle , the valve frame support body 1 is provided with a hollow cavity with openings at both ends; the valve frame support body 1 cavity inner wall is provided with an artificial valve leaflet 2; the valve frame support body 1 and the interventricular septum are provided with an interventricular septum anchoring structure 3. The horizontal cross-section of the end of the valve support body 1 close to the atrium is set as a D-shaped structure matching the closing edges of...

Abstract

The invention relates to a mitral valve replacement system for a percutaneous transcatheter, and belongs to the technical field of medical instruments. The mitral valve replacement system comprises avalve frame supporting body, an artificial valve leaflet and a ventricular septum anchoring structure. The valve frame supporting body is arranged between an atrium and a ventricle and provided with ahollow cavity with the two ends open. The artificial valve leaflet is arranged on the inner wall of the cavity of the valve frame supporting body. The ventricular septum anchoring structure is arranged between the valve frame supporting body and a ventricular septum. The invention provides the mitral valve replacement device intervened through a catheter via a femoral vein admission passage and aims to solve the problems that an existing interventional mitral valve system is generally large in valve stent, has the left ventricular outflow passage obstruction risk, has potential complicationsin transapical admission passage and anchoring and the like, and the mitral valve replacement device provided by the invention is more minimally invasive and firmer in anchoring, and the technical scheme of mitral valve replacement suffering from left ventricular outflow tract obstruction can be effectively avoided.

Description

technical field [0001] The invention relates to a percutaneous transcatheter mitral valve replacement system, which belongs to the technical field of medical devices. Background technique [0002] Mitral valve disease is a common heart valve disease, and it is also the largest group of heart valve surgery, accounting for about 60%, and mitral regurgitation is the most common mitral valve disease. When the left ventricle contracts in patients with mitral valve regurgitation, blood flows through the left ventricle into the aorta, and at the same time, part of the blood enters the left atrium with less resistance through the incompetent mitral valve. In patients with severe regurgitation, the blood flowing into the left atrium may be Up to more than half of the left ventricular output, the increase in left atrial volume will lead to an increase in left atrial pressure, which in turn can cause pulmonary vein and pulmonary capillary pressure to increase, dilation and congestion. ...
