An apparatus and method for selective delivering fluid into a fluid vessel is provided. In the method, a delivery catheter (2) is advanced over a guide wire (30) to a target location within fluid vessel, such as a restriction or blockage. After reaching the target location, therapeutic fluid is supplied under pressure into an axial lumen 12 of the delivery catheter. The fluid is inhibited from passing through the open distal end of the catheter so that the fluid will preferentially flow radially outward through a plurality of lateral infusion ports (20) in the delivery catheter. The guide wire may also be retracted into the catheter to deliver the fluid axially through the open distal end of the catheter.
