The invention discloses an artificial heart valve support, an artificial heart valve, and an artificial heart valve replacement system. The artificial heart valve stent includes an inner stent and an outer stent connected to each other; the outer stent includes an outer body section, and an outer skirt section extending from the outer body section and positioned radially outside the outer body section, wherein the outer skirt The side section is located between the inflow end and the outflow end of the outer body section; the inner frame includes an inner body section at least partially inside the outer frame, and a radial channel protruding from the inflow end of the inner body section to the inner body section. The outer inner skirt section; wherein the inner skirt section protrudes outward radially outside the inflow end of the outer body section, the outer skirt section, the inner skirt section, and the outer body section are located between the outer skirt section and Sections between the inner skirt sections jointly form an accommodating space that is open radially outward. The artificial heart valve support can reduce the damage to valve ring tissue.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an artificial heart valve support, an artificial heart valve with the artificial heart valve support, and a replacement system for the artificial heart valve. Background technique [0002] Heart valves play an important one-way "valve" role in the heart's blood circulation, preventing backflow of blood. The mitral valve (which prevents backflow of blood from the left ventricle (abbreviation: LV) to the left atrium (abbreviation: LA)) and the tricuspid valve (which prevents backflow of blood from the right ventricle (abbreviation: RV) into the right atrium (abbreviation: Abbreviation: RA)) is an important heart valve, usually including valve annulus, leaflets, chordae and papillary muscles. The leaflets of a normal mitral or tricuspid valve close tightly when the ventricle is contracted to completely block the backflow of blood from the ventricle to the atrium, but the le...
