A dilatation catheter for angioplasty procedures having inner and outer tubular members with a reinforcing mandrel fixed within the annular lumen between the the inner and outer tubular members. The catheter is adapted for use with a guidewire having an OD of not more than 0.014 inch (0.356 mm), preferably less than about 0.012 inch (0.305 mm). The mandrel has a small diameter distal section which extends into the portion of the dilatation catheter which extends out of the distal end of the guiding catheter and into the patient's coronary artery during the angioplasty procedure. |
