Abstract
A balloon catheter includes a shaft, and a balloon provided outside the shaft. A drug is provided on an outer surface of the balloon, and the balloon has at least a straight tube part. A change ratio of an outer diameter of the straight tube part, (D28−D24)/D24, is 1.1% or less. D24 is the outer diameter of the straight tube part when an internal pressure of 2.43 MPa (24 atm) is applied, and D28 is the outer diameter of the straight tube part when an internal pressure of 2.84 MPa (28 atm) is applied.
