Abstract

There is provided herein a supra mitral device for mitral / tricuspid valve repair in a subject in need thereof, the device comprising: a main body portion having essentially annular D-shape with an eccentric opening, such that a posterior section of said main body portion is wider than an anterior section of said main body portion, said posterior section of said main body portion configured for coverage and attachment to essentially the whole section of the posterior leaflet of the mitral valve which faces the left atrium on systole, thereby preventing and / or reducing mitral regurgitation, wherein said posterior section of said main body portion is made of a pliable material, adapted to stiffen after implantation of the device.

Description

technical field [0001] The present disclosure generally relates to devices and methods for transcatheter atrioventricular valve (i.e., mitral and tricuspid) repair or replacement, commonly referred to as transcatheter mitral valve replacement ( TMVR) or transcatheter mitral valve repair (TMVRr), or percutaneous mitral valve repair or replacement (PCMVR). Background technique [0002] The atrioventricular valve is a one-way valve that, as the name suggests, is a passage from the atria to the ventricles. On the left side of the heart, between the left atrium and left ventricle is the mitral valve. On the right side of the heart, between the right atrium and right ventricle is the tricuspid valve. Their basic anatomy is very similar. The mitral valve device has three parts: 1) the leaflets, which function like a door in a one-way gate and actually prevent the backflow of blood from the left ventricle into the left atrium; 2) the chordae (chordae), which hold the leaflets at ...
