Embodiment Construction

[0027] The principles and features of the present invention will be described below in conjunction with the accompanying drawings and specific embodiments. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0028] In the description of the present invention, if terms such as "up", "down", "left", "right", "top", "bottom", "inside" and "outside" are used to indicate orientation, the indicated The orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be configured in a specific orientation, and operation, and therefore should not be construed as limiting the invention.

[0029] like Figures 1 to 6 As shown, the present invention pr...

Abstract

The invention relates to a mitral valve repair stent which comprises a skeleton and a valve assembly, the skeleton comprises an upper limiting piece, a middle fixing piece and a lower limiting piece, the middle fixing piece comprises a V-shaped supporting section, a first sleeve and a second sleeve, the V-shaped supporting section is connected with the lower end of the first sleeve and the lower end of the second sleeve; a front wing and a rear wing are correspondingly arranged on the front side and the rear side of the top of the valve assembly, the upper limiting piece comprises a first limiting curve section located above the front side and a second limiting curve section located above the rear side, the first limiting curve section and the second limiting curve section are connected with the upper ends of the first sleeve and the second sleeve on the left side and the right side respectively, and the middle parts of the first limiting curve section and the second limiting curve section are respectively concave inwards to form a front V-shaped connecting section and a rear V-shaped connecting section which are correspondingly connected with the front wing and the rear wing. The mitral valve repair stent has the advantages that after the stent is improved, the action on the atrial wall is small, the self-adaptive attaching and anchoring effect at the valve ring is good, the improved valve assembly is good in compliance and is matched with the improved stent, better closing performance is achieved, the complication probability is low, and the postoperative effect is good.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a mitral valve repair bracket. Background technique [0002] There are about 10 million patients with mitral valve regurgitation (≥grade 3) that need to be treated in China. The volume of mitral valve surgery is more than 40,000 cases per year. Severe mitral valve regurgitation can cause symptoms such as palpitations, chest tightness, and shortness of breath, and eventually lead to heart failure and death. Surgical valve repair or replacement is considered the standard treatment for this disease. However, surgery has disadvantages such as large trauma, high risk, and slow recovery. Therefore, the development of minimally invasive and low-risk interventional treatment devices for mitral valve regurgitation has huge social benefits and market demands. [0003] Interventional treatment devices for mitral valve regurgitation have become one of the key directions in the r...
