ABSTRACT:
A vascular catheter for delivering a uniform flow of therapeutic fluid over a length of the catheter. The catheter is particularly suitable for delivering thrombolytic agents to a thrombus or clot in a patient's arterial system. In a preferred embodiment, the catheter has a relatively thick-walled tubular body with a central lumen for advancement over a guidewire and a plurality of fluid delivering lumens disposed within the relatively thick wall. Each of the smaller lumens has a single flow passageway to discharge therapeutic fluid to the exterior of the catheter.
