The present invention provides a biological duct stent that suppresses elongation in a cylinder axis direction and deformation in a radial direction, and improves post-deformation resilience and deformation resistance. A biological duct stent formed of a knitted fabric, a braided woven fabric, or a tubular knitted fabric of a bioabsorbable fiber 3 in a tubular body 1 having a knitted structure, wherein the tubular body is in the middle of a cylinder axis direction. Has a joint. The joint 2 is any one of welding, fusion, adhesion, and stitching. The cylindrical body 1 is configured by joining ends of cylindrical bodies having a short overall length in a cylindrical state in a series state by a desired length. The joint portion 2 includes a branch joint portion that branches from one cylindrical body 1 into a plurality of cylindrical bodies. [Selection] Figure 1 |
