Cardiac apex implantation mitral valve clamping device and cardiac apex implantation mitral valve clamping method

Abstract

The invention discloses a cardiac apex implantation mitral valve clamping device and a cardiac apex implantation mitral valve clamping method. The cardiac apex implantation mitral valve clamping device comprises an upper connecting piece, the upper connecting piece is sequentially provided with a sealing end piece and a central woven net, a rod penetrating cavity is formed in the central woven net, and an upper connecting mechanism is arranged at the near end of the sealing end piece; an inner frame net is connected with the lower end of the central woven net to form an integrated structure; the outer edge of an outer frame net is integrally connected with the outer edge of the inner frame net, a lantern ring is arranged in the middle of the outer frame net, and a lower connecting mechanism is arranged on the outer ring surface of the lantern ring; an elastic clamp is fixed on the surface of the inner frame net; a clamp opening mechanism is used for controlling the elastic clamp to open; and the initial memory state of the outer frame net is that the outer frame net is folded towards the far end to wrap the inner frame net and the elastic clamp. During compression intervention, thecaliber of the clamping device is greatly reduced, a small-caliber sheathing canal can be intervened, the operation difficulty and strength of an operation are reduced, the large-width elastic clampcan be adopted, the capture success rate is increased, the elastic clamp is independently controlled through a corresponding pull wire, capture valve leaflets are easy to control, and universality ishigh.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for clamping a mitral valve implanted in the apex of the heart and a clamping method for the mitral valve implanted in the apex of the heart. Background technique [0002] With the aging of the population, the incidence of heart valve disease is gradually increasing, followed by the incidence of mitral regurgitation is also showing a rising trend. According to statistics, among heart valve diseases, mitral valve disease accounts for 70% of valve diseases, which accounts for a large proportion. [0003] With the development of science and technology, domestic and foreign device manufacturers have developed a batch of interventional devices for the treatment of mitral valve regurgitation. Among them, Abbott MitraClip and Edward PASCAL are typical representatives. MitraClip was popularized earlier in clinical practice. The mechanical working principle of the clip ...
