Multifunctional mitral valvuloplasty device

Abstract

The present invention relates to a multifunctional mitral annulus forming device, comprising an adjustable forming ring body and a support member connected to the forming ring body and supported on the deformation side of the left ventricle; the support member is away from the forming ring along the length direction The body end has a ring-shaped structure; it is beneficial to form an effective support for the displacement and deformation of the left ventricle; it is beneficial to ensure that the front and rear leaflets remain in the normal position without damaging the papillary muscle when the chord tendon falls off or breaks, and it is beneficial to systole The normal closure of the front and rear valve leaflets; it is beneficial to avoid secondary mitral regurgitation of different degrees, and solve the problem of different degrees of mitral regurgitation secondary to displacement deformation; and the structure is simple, the operation is convenient, and the manufacturing process is simple. The manufacturing cost is low and the reliability is high.

Description

technical field [0001] The invention relates to a mitral valve forming device, in particular to a multifunctional mitral valve forming device. Background technique [0002] Ischemic mitral regurgitation (ischemic mitral regurgitatiolq, IMR) is mitral regurgitation secondary to ischemic heart disease and myocardial infarction. In view of the absence of typical pathological lesions in the mitral valve leaflets and chordae, IMR is understood as a functional mitral regurgitation. [0003] Compared with replacement, the existing mitral annuloplasty is easier to maintain excellent hemodynamic characteristics, promote the recovery of left heart function, and the incidence of perioperative complications such as death, thromboembolism, bleeding, and endocarditis is also lower. Lower, postoperative free from regurgitation is also significantly better than mitral valve replacement. However, although plastic surgery is safe, easy to perform, and has few complications, there are still ...
