Problems solved by technology

All three are implanted through the apical method, which has the disadvantage of greater trauma compared with the traditional TAVR valve implanted through the femoral artery
It can be found that such a product system is complex to operate and has high requirements for doctors' operations, and there are obvious deficiencies

Embodiment Construction

[0033] The inventors of the present application found that the use of a valve fixed solely by radial support force cannot achieve good results in the treatment of aortic regurgitation, which is specifically manifested in the problems of unstable anchoring and easy movement. achieve a good therapeutic effect. The new type of valve using the clamping valve leaflet method is used for the treatment of aortic regurgitation through the apical method, which is traumatic and complicated to operate, specifically manifested in the structure of the valve leaflet clamping with clips, the overall size of the valve is large, and it needs to be used Compared with transfemoral implantation of traditional TAVR valves, transapical implantation is more traumatic, which is not conducive to the postoperative recovery of elderly patients. The method of implanting the clamp and the valve successively through the transapical method, in addition to the disadvantage of trauma compared with the transfem...

Abstract

The invention provides a heart valve prosthesis. The heart valve prosthesis used for replacing the original valve in the human body, the original valve comprises a valve ring, the heart valve prosthesis comprises a bracket body, an artificial valve leaflet fixed to the bracket body, and a convex structure distributed on the side wall of the bracket body; and when the heart valve prosthesis is placed in the human body, the convex structure is arranged above the valve ring, and thus the position of the heart valve prosthesis is limited. The convex structure is arranged above the valve ring, thusthe position of the heart valve prosthesis is limited, under the unfolding state, the heart valve prosthesis can lean above the valve ring depending on the lower part of the convex structure, so thatthe phenomenon that the heart valve prosthesis moves towards the ventricle is prevented, therefore, the anchoring of the heart valve prosthesis at the release position under the condition without calcification of the root of the valve is effectively realized, and thus the stable implantation of the heart valve prosthesis is realized.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a heart valve prosthesis. Background technique [0002] At present, transcatheter aortic valve replacement (TAVR for short) is mainly used for the treatment of severe aortic stenosis, while the TAVR treatment of aortic regurgitation is still being explored. Aortic regurgitation means that when the heart is in diastole, the aortic valve does not close tightly so that the blood that has flowed into the aorta flows back to the left ventricle. Mild to moderate aortic regurgitation may have no obvious symptoms, and patients with moderate to severe aortic regurgitation may experience a period of cardiac compensation, and the average survival after loss of compensation is only 2 to 5 years. [0003] Most of the existing TAVR valves use self-expanding stents (represented by Medtronic Core-Valve) or balloon-expandable stents (represented by Edwards Sapien) to fix the stent to...
