一种支架式心脏瓣膜及其支架

Stent type heart valves and stent thereof

Abstract

The invention discloses a stent, and the stent comprises an annular part which can be circumferentially extended, an ascending aorta part and a sinus part for connecting the annular part and the ascending aorta part, wherein a neck part which is concave is arranged between the sinus part and the ascending aorta part; the sinus part and the ascending aorta part are separated by the neck part so that the sinus part and the ascending aorta part can move independently, thus the ascending aorta part and the sinus part are separated by the neck part, and in the process of the use of stent type heart valves, the deformation of the sinus part does not affect the ascending aorta part, and the sinus part can be fully extended when the ascending aorta part remains in a conveying system, so that the heart valves can work ahead, the influence of the blood circulation to a patient is reduced, the performance of the stent type heart valves is improved. The invention further discloses the stent type heart valves which comprise the above-mentioned stent.
本发明公开了一种支架,该支架包括可周向扩展的环状部、升主动脉部以及连接所述环状部和所述升主动脉部的窦部,其中,窦部与升主动脉部之间设置有内凹的颈部,颈部将窦部与升主动脉部相分隔,以便窦部与升主动脉部能够独立运动;这样,通过颈部将升主动脉部与窦部相分离,在支架式心脏瓣膜的使用过程中,窦部的形变不会对升主动脉部造成影响,则升主动脉部仍保留在输送系统内时窦部就可以完全展开,从而使心脏瓣膜提前工作,减少对患者血液循环的影响,提高了支架式心脏瓣膜的性能。本发明还公开了一种包括上述支架的支架式心脏瓣膜。
