Beschreibung
Zusammenfassung:	An indwelling catheter is made of a polyurethane resin having a Shore hardness of 60D or more. The soft segment of the polyurethane resin is constituted by polycaprolactone. The indwelling catheter has a kinking resistance of 10 mm or more when measured at 37 DEG C in a wet state. The Young's modulus is at first 20 kgf/mm or more when measured at 25 DEG C in a dry state, and reduces to 15 kgf/mm or less by soaking it in water at 37 DEG C for 5 minutes or less.
