BIO-COMPATIBLE METAL STENT AND SCAFFOLD FOR REGENERATIVE MEDICINE OF LUMINAL ORGAN

摘要

PPROBLEM 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. PSOLUTION: 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 TiSB100-X-Y/SBZrSBX/SBNbSBY/SB(wherein, 20 wt.%X35 wt.% and 20 wt.%Y30 wt.%).
