Abstract
An over-the-wire balloon dilatation catheter of the short guide wire lumen type has a stainless steel hypotube catheter shaft section, a distal plastic shaft section attached to the hypotube and a balloon connected to the distal plastic shaft section. A relatively short guide wire lumen extends throughout the length of the balloon. The distal shaft section includes a reinforcing and kink-resistant transition member extending throughout the length of the distal shaft section. The transition member allows the proximal guide wire lumen aperture to be placed distally from the distal end of the hypotube. This configuration permits the length of the guide wire lumen to be minimized.
