摘要

A catheter (1) for insertion into a branched blood vessel is a catheter for insertion into a branched blood vessel that branches from a first blood vessel. The catheter (1) has a catheter main body (2) having an inner lumen (20) for insertion of a guide wire (15). The catheter main body (2) is equipped with an inner layer (3), a wire-wrapped reinforcing body (5) provided on the outer surface of the inner layer (3), and an outer layer (4) that covers the inner layer (3) and wire-wrapped reinforcing body (5). The catheter main body (2) is equipped with a first point of change in physical properties (6) located 3.0-7.0 mm from the tip, and the rigidity is higher on the base end side than on the tip side in front of and behind the first point of change in physical properties (6).
