<P>PROBLEM TO BE SOLVED: To provide a biological duct stent whose stretch in a tube axial direction and deformation in a radial direction are suppressed and restorability after deformation and deformation resistance are improved. <P>SOLUTION: The biological duct stent is configured in the cylindrical body 1 of net-like tissue by the knitting, braid-like textile or tube knitting of bioabsorbable fibers 3, and the cylindrical body has a joint part 2 in the middle of the tube axial direction. The joint part 2 is one of welding, fusion bonding, bonding and suturing. The cylindrical body 1 is configured by joining the end parts of the cylindrical bodies of the short length in a serial state for a desired length in the tube axial direction. The joint part 2 includes a branched joint part branched into the plurality of cylindrical bodies from one cylindrical body 1. <P>COPYRIGHT: (C)2009,JPO&INPIT |
