Abstract

Apparatus and method is disclosed relating to an infusion catheter for treating a subject region with a treatment solution. A guide catheter allows the infusion catheter to be inserted into the subject and placed near a treatment region within the vascular system. A solution source is used to selectively inflate an infusion device. A passageway in the catheter body extends to an infusion device which has inner and outer chambers. Holes in a wall of the inner chamber route solution into the outer chamber and holes in the wall of the outer chamber route the solution into a subject vasculature. Solution pressure in the inner chamber is greater then the solution pressure in the outer chamber due to the relatively greater area of the holes in the outer chamber wall.
