ABSTRACT:
A perfusion catheter of the invention has an improved short, distal perfusion portion with a high flow rate. The distal perfusion portion has at least two rows of circumferentially disposed perfusion ports and is preferably tapered in the distal direction from larger cross-sectional dimensions to smaller cross sectional dimensions, with the number of perfusion ports in the most distal row of circumferentially disposed perfusion ports being less than the number of a perfusion ports in a row of perfusion ports proximal to the most distal row. The distal perfusion portion is most conveniently formed from a distal skirt of a dilatation balloon on the distal section of the catheter.
