MEDICAL ELONGATED BODY AND BALLOON CATHETER

Abstract: a medical elongated body in which a bonding strength between a catheter shaft and a distal member is increased while the flexibility of a distal portion is maintained. the medical elongated body includes a catheter shaft that extends in an axial direction and is provided with an outer layer and an inner layer, a distal member that is fused to a distal side of the catheter shaft and is more flexible than the catheter shaft, in which in a cross-sectional view in the axial direction, a distal portion of the inner layer intrudes in an arc outward in the radial direction from an inner surface of the distal member, and a distal portion of the outer layer intrudes in an arc inward in the radial direction from an outer surface of the distal member.
