ABSTRACT:
A dilation catheter for use in performing angioplasty procedures. The catheter includes a relatively long catheter shaft which has two lumens. A relatively short guidewire receiving tube is thermally bonded to the distal end of the shaft, with its lumen approximately aligned with one of the lumens of the catheter shaft and a stiffening wire positioned therein. A dilation balloon, preformed with a shape that enables it to be used in an offset configuration, is thermally bonded to the distal and proximal ends of the tube, with its lumen aligned with the remaining lumen of the catheter shaft. The balloon and tube together define channels for the perfusion of blood past the balloon, which channels remain open even when the balloon bears against the tube during the inflation thereof.
