Abstract
The intravascular balloon catheter has an elongated shaft defining an inflation lumen and a guidewire lumen, as well as a balloon disposed near the distal end of the shaft. The inflation lumen communicates with and provides pressurized inflation fluid to the interior volume of the balloon, and the guidewire lumen is adapted to slidingly receive a guidewire. The shaft is formed of a length of flexible plastic tube, and the inner surface of the guidewire lumen is lined with an inner plastic layer. The plastic materials of the outer tube and inner layers are different, and they may be chemically bonded to each other.
