<P>PROBLEM TO BE SOLVED: To provide an artificial valve cusp for implantation regenerated as a self-organization after implanted, and a manufacturing method therefor. <P>SOLUTION: This artificial valve cusp for the implantation has a shape simulated with a valve cusp of a human cardiac valve, is formed of a material derived from an animal tissue serving as a footing for regenerating a cell, and is constituted to make a DNA amount zero. The cell is thereby easy to get in the artificial valve cusp for the implantation, because only the artificial valve cusp for the implantation is implanted to a blood vessel tissue of a patient, which is different from a case of implanting a blood vessel tissue including the cardiac valve, and the artificial valve cusp for the implantation is self-organized further. <P>COPYRIGHT: (C)2012,JPO&INPIT |
