BIO-COMPATIBLE METAL STENT AND SCAFFOLD FOR REGENERATIVE MEDICINE OF LUMINAL ORGAN |
摘要 |
<P>PROBLEM TO BE SOLVED: To develop a new scaffold for regenerative medicine of a luminal organ made of a biomaterial which does not cause stenosis during chronic stage and has a high degree of safety that can withstand long-term indwelling within the human body considering that the scaffold is used within the living body and is brought into direct contact with the body liquid. <P>SOLUTION: The scaffold for regenerative medicine of a luminal organ comprises a tube member (1) for regenerative medicine of a luminal organ made of a biomaterial and a tubular shape maintaining member (2a) made of a bio-compatible metal material which is arranged along the whole periphery of the tube member (1) to cover the whole periphery and has a flexible mesh structure. The scaffold is characterized by that the composition of the tubular shape maintaining member (2a) is expressed by Ti<SB>100-X-Y</SB>Zr<SB>X</SB>Nb<SB>Y</SB>(wherein, 20 wt.%<X≤35 wt.% and 20 wt.%<Y≤30 wt.%). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
