The present invention is a wire used for stents inserted into blood vessels such as coronary arteries, which is made of poly (L-lactide), a bioabsorbable polymer, and has a crystallinity of 15% to 60 measured by differential scanning calorimetry. It is in%. This wire rod is a monofilament, and its diameter is formed from 0.08 mm to 0.30 mm. The monofilament is shaped into a cylindrical structure to form a vascular stent.n n n n Vascular stent, bioabsorbable, poly (L-lactide), monofilament, crystallinity, wire rod, patency |
