Heart valve prosthesis, artificial valve formed by same, and preparation method therefor

A heart valve prosthesis, comprising a support element of a tubular structure, and at least two lobule bodies connected to the inner wall of the support element, wherein

• the support element comprises an outer layer fabric having selvages on two opposite sides, and a suture line for fixing the other two sides of the outer layer fabric to each other to form the tubular structure;
• each of the lobule bodies is formed by stacking at least one lobule layer;
• and two opposite sides of the lobule body are respectively an interwoven side and a free side, with the interwoven side being fixed between the two selvages of the outer layer fabric by means of weaving, and the free side being a selvage;
• wherein each of the lobule layers is formed by interweaving an inner side warp and an inner side weft;
• the interwoven side of the lobule body is fixed by means of weaving the inner side weft of each of the lobule layers onto the outer layer fabric;
• and the inner side warp is woven on the inner side weft;
• wherein the number of yarns forming the inner side weft of each of the lobule layers is one;
• and the number of yarns forming the inner side warp of each of the lobule layers is also set to be one.
