    • PROBLEM TO BE SOLVED: To provide an improved artificial heart valve.SOLUTION: An artificial heart valve (10) (for example, an artificial aortic valve) can be compressed a little around the circumference and can be expanded again. In the compressed state, the valve is used for a non-invasive distribution into a patient. The valve is expanded again into an ordinary operation size, when it reaches a transplantation side in the patient, and fits the peripheral tissue of the patient. The valve includes a stent portion (200) and a ring portion (100), and the ring portion is substantially concentric to the stent portion but is downstream of the stent portion in the direction of the blood flow through the implementation portion. When the valve is implanted, the stent portion fits the tissue of the patient to a natural valve ring or near the natural valve ring. On the other hand, the ring portion snaps the tissue (for example, an aorta) which is positioned downstream of the natural valve.
    • 要解决的问题:提供一种改进的人造心脏瓣膜。解决方案:人造心脏瓣膜(10)(例如,人造主动脉瓣)可围绕圆周进行压缩,并可再次扩张。 在压缩状态下,阀被用于非侵入性分布到患者体内。 当瓣膜到达患者的移植侧时,阀再次膨胀成普通的操作尺寸,并适合患者的外周组织。 所述阀包括支架部分(200)和环形部分(100),并且所述环部分与所述支架部分基本上同心,但是在通过所述实施部分的血液流动方向上在所述支架部分的下游。 当植入瓣膜时,支架部分将患者组织装配到天然瓣环或靠近天然瓣环。 另一方面,环部分咬合位于自然阀下游的组织(例如,主动脉)。
