Abstract: A balloon catheter for medical treatment of a patient has an improved tip design and methods of making the tip. The balloon catheter has a flexible shaft with proximal and distal ends, a hub affixed to the proximal end, and a balloon affixed to the shaft near the distal end. At least a distal portion of the shaft includes a tubular inner body, and the balloon has a distal leg affixed to the inner body. A short, tubular tip member is placed in contact with the distal end of the inner body, and a shrink tube is placed around the point of contact. A wire mandrel is passed through a lumen defined by the inner body and tip member. While the shrink tube is heated, compressing the tip member and inner body, the mandrel is moved. This combination of heat, radial pressure, and mandrel movement causes a blending of the materials of the inner body and the tip member. The resulting joint of the tip member and inner body is both strong and flexible.

Abstract translation: 用于患者医疗的球囊导管具有改进的尖端设计和制造尖端的方法。 球囊导管具有柔性轴，其具有近端和远端，固定到近端的轮毂，以及靠近远端固定到轴的球囊。 轴的至少远端部分包括管状内体，并且气囊具有固定到内体的远侧腿。 短管状尖端构件与内体的远端接触放置，收缩管围绕接触点放置。 线心轴穿过由内体和尖端构件限定的内腔。 当收缩管被加热时，压缩尖端构件和内部主体，心轴被移动。 热，径向压力和心轴运动的这种组合导致内体和尖端构件的材料的混合。 所述尖端构件和内体的接合部既牢固又灵活。
