The utility model relates to a medical appliance, in particular to a novel catheter which comprises a catheter and an annular inflatable balloon which is fixed at the end of the catheter, wherein the end part of the catheter is provided with a catheterization hole and the catheter end is closed. The catheter is characterized in that at the part 15-40mm behind the annular inflatable balloon of the catheter, continuous protruding strips are additionally and uniformly distributed along the longitudinal direction of the catheter, the continuous protruding strips which are longitudinally and uniformly arranged are solid continuous protruding strips or hollow continuous protruding strips, or are staggered solid and hollow continuous protruding strips, and the outline of the cross section of the protruding strip is approximately circular or oval. Through changing the surface structure of the traditional balloon catheter, the utility model improves the air permeability, reduces the occurrence of complication caused b
