Abstract

The present invention relates to an artificial leaflet used in mitral leaflet plasty for reconstructing mitral leaflet. Also, the present invention relates to an apparatus for manufacturing the artificial leaflet. According to the present invention, the artificial leaflet used in the mitral leaflet plasty can be easily manufactured according to the size of patient's mitral leaflet, thereby enabling the heart function to be recovered and maintained by reconstruction of the mitral leaflet to be close to the original form of the mitral leaflet. Therefore, the artificial leaflet can be used in mitral leaflet plasty for reconstructing mitral leaflet in the medical industry.
