ABSTRACT:
This invention relates to a balloon dilatation catheter which comprises a first, inflation lumen extending therethrough and having distal and proximal ends, the distal end of the first lumen opening into and being in fluid communication with the interior of an inflatable dilatation balloon having distal and proximal ends, and a second lumen extending coextensively with the first lumen and having proximal and distal portions. The distal end of the second lumen is open, the distal portion of the second lumen has an opening proximal to the proximal end of the dilatation balloon, the portion of the second lumen distal to the opening is enlarged as compared to the proximal portion to facilitate receiving a guidewire in a sliding fit, and the portion of the second lumen proximal to the opening contains a pushing wire.
