Abstract

The invention relates to a mitral valve interventional valve and a delivery system. The interventional valve comprises a valve frame, a valve skirt and a valve leaflet, the valve skirt fixedly covers the inner wall of the valve frame, the valve leaflet is connected to the valve skirt, and when the valve frame is in an unfolded state, an eversion structure is formed at one end of the valve frame; and the interventional valve further comprises an adjusting structure, one end of the adjusting structure is fixed to the valve frame or the valve skirt, the other end of the adjusting structure is an operation end, and the operation end is used for adjusting the implantation position of the mitral valve interventional valve through external force traction. According to the interventional valve, the implantation state can be further adjusted through the adjusting structure after implantation, so that it is guaranteed that the implantation position of the interventional valve can be effectively matched with a valve ring, and perivalvular leakage is prevented; and besides, the operation end of the adjusting structure can be fixed at the apex of the heart, so that the interventional valve can be always restrained, and structures such as barbs are matched, so that reliable matching of the interventional valve and the valve ring is guaranteed, and perivalvular leakage caused by ineffective matching of the interventional valve and the valve ring due to the fact that the interventional valve moves towards the atrium is avoided.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a mitral valve interventional valve and a delivery system. Background technique [0002] The interventional therapy of transapical mitral valve is an emerging discipline. After opening the chest cavity, the mitral valve interventional valve is delivered to the position of the mitral valve annulus through the delivery system through the apex for release. However, due to the complex physiological structure of the mitral valve, the front and rear rings have a certain inclination angle, and the shape of the ring is D-shaped or elliptical, so there are high requirements for the release height and angle of the interventional valve; at the same time, Since the valve release claws used to release the interventional valve in the delivery system cannot be controlled independently by the delivery system, it is difficult to meet the requirements for the release height and a...
