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.
