ARTIFICAL HEART VALVE STENT FOR ATRIOVENTRICULAR VALVE, INTERVENTIONAL INSTRUMENT, CONTROL HANDLE, CONVEYING SYSTEM, LOADING METHOD AND RELEASE METHOD

A prosthetic heart valve stent for atrioventricular valve, an interventional device (900), a control handle (100), a delivery system, a loading method and a release method are disclosed. The interventional device (900) includes an inner frame (300) and an outer frame (400) around the inner frame (300), the inner frame (300) and the outer frame (400) both have radially deformable and cylindrical mesh structures, the inner frame (300) encloses and defines a blood flow channel (301), and the prosthetic heart valve stent has an inflow side (910) and an outflow side (920) opposite to each other according to a direction of blood flow; the prosthetic heart valve stent further includes an anchoring arm (500), one end of the anchoring arm (500) being connected to the inner frame (300), the other end extending outward beyond the outer frame (400), and the part extending beyond the outer frame (400) being bent towards the inflow side (910) and used for positioning and engaging with a surrounding tissue. The interventional device (900) is engaged with the surrounding tissue by using the inner frame (300) and outer frame (400), increasing use stability of the interventional device (900).
