  • Lubricious yet bondable catheter channel sleeve for over-the-wire catheters
    Patent number: 5304134
    Abstract: The inner tubular element of an annular over-the-wire dilatation balloon catheter defines the guidewire lumen extending through the catheter shaft and the balloon and is bonded to the balloon at the distal opening of the balloon. In accordance with the invention, the inner tubular element is constructed in two segments. The proximal segment is constructed of a polymer such as polyethylene which has a lubricious surface, while the distal segment is constructed of a polymer such as nylon, polyurethane, or a nylon/polyurethane blend, which lacks lubricity but forms a secure bond with the balloon at the distal opening. The bond by which the proximal and distal segments are joined is thus removed from the distal balloon opening, and accordingly less susceptible to failure upon pressurization of the balloon.
