    Abstract: Balloon catheter includes an elongate tubular shaft having an outer tubular member having proximal and distal portions, and an inner tubular member having a distal length extending distally from the distal portion of the outer tubular member. The elongate tubular shaft has an inflation lumen and a guidewire lumen defined therein. The guidewire lumen extends along at least the distal length of inner tubular member. The balloon catheter also includes a distal end section coupled to a distal end of the inner tubular member and having a proximal end and a distal end. The balloon catheter also includes a balloon having a proximal portion sealingly coupled to the distal portion of the outer tubular member, a distal portion sealingly coupled to the distal end section, and a working length therebetween. The balloon defines an inner chamber. The proximal end of the distal end section is disposed within the inner chamber.

    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.

    Abstract translation: 一种具有细长轴和远侧轴部分上的气囊的导管，所述细长轴包括外部管状构件和内部管状构件，所述内部管状构件具有接合部分，所述内部管状构件的外表面沿着所述接合部分结合到内部表面 的外管状构件。 内部管状构件具有靠近接合部分的近侧部分和远离接合部分的远侧部分，具有比其近端部分更高的轴向压缩刚度和柱强度。 导管具有改进的跟踪性，轴向抗塌陷性，推挤性和可交叉性，以改善将球囊定位在患者体腔内的期望位置的能力。
