PROBLEM TO BE SOLVED: To provide a premolded tubular catheter for insertion of a catheter by a percutaneous radial artery oriented approach. SOLUTION: This catheter has a bridge type part 1 on the tip side. The bridge type part 1 has a tip side arch 2 forming a primary curved part 3, a top part 4 forming a secondary curved part 5 and an arch 6 on the base end side forming a tertiary curved part 7. The arch 6 on the base end side is connected to a straight shaft 9. The shaft 9 has rigidity. The bridge type part 1 has a flexible part and a rigid part. The flexible part elongates at least to the primary curved part 3 while containing the primary curved part. The rigid part elongates at least to the tertiary curved part 7 while containing the tertiary curved part. |
