Abstract: Catheter includes an outer shaft member having a proximal section and a distal outer member. The outer shaft has an inflation lumen defined therethrough. A balloon is in fluid communication with the inflation lumen and has a proximal balloon shaft, a proximal cone portion, a working length, a distal cone portion, and a distal balloon shaft. Catheter also includes a monolithic inner tubular member extending from the outer shaft proximal section through the distal outer member and through the balloon to form a tip. The distal balloon shaft has an inner diameter and comprises a distal seal portion coupled to the inner tubular member and a proximal portion free of attachment to the inner tubular member. The length of the proximal portion of the distal balloon shaft is at least about two times the inner diameter of the distal balloon shaft. Methods of making a catheter are also provided.

Abstract: A catheter having an elongated shaft and a balloon on a distal shaft section, the elongated shaft comprising an outer tubular member, and an inner tubular member which has a bonded portion along which an outer surface of the inner tubular member is bonded to an inner surface of the outer tubular member. The inner tubular member has a proximal portion proximal to the bonded portion, and a distal portion distal to the bonded portion with higher axial compression stiffness and column strength than the proximal portion thereof. The catheter has improved trackability, axial collapse resistance, pushability, and crossability, for improved ability to position the balloon at a desired location in a patient's body lumen.
