A dilatation catheter is disclosed having an inflation balloon and a catheter shaft with an inflation channel. A first guidewire channel is disposed along the dilatation catheter and has a distal exit at the distal end of the catheter shaft. A second guidewire channel is disposed along the dilatation catheter and has a distal exit attached along the inflation balloon. Guidewires are slideably disposed within the first and second guidewire channels. An oblique ended expandable stent is disposed about the inflation balloon and used to treat bifurcated and sidebranched arteries and ostial lesions.
