  • STENT, METHOD FOR MANUFACTURING STENT, AND METHOD FOR SECURING AIR FLOW BY RELIEVING STENOSIS OF RESPIRATORY ORGAN
    Publication number: 20250049555
    Abstract: A stent for a respiratory organ includes a bioabsorbable polyester copolymer. The bioabsorbable polyester copolymer is a polyester copolymer having residues of two kinds of ester bond forming monomers as main constituent units, and where the two kinds of ester bond forming monomers are referred to as monomer A and monomer B, respectively, an R value given by the following formula is 0.25 or larger and 0.99 or smaller: R=[AB]/(2[A][B]) 100. In the formula, [A] is a mole fraction (%) of monomer A residues in the polyester copolymer; [B] is a mole fraction (%) of monomer B residues in the polyester copolymer; and [AB] is a mole fraction (%) of structures (A-B and B-A) in which a monomer A residue and a monomer B residue are adjacent to each other in the polyester copolymer.
