A method for infusing a liquid into a patient's vasculature using an infusion protocol is disclosed. For this method, an infusion catheter having a multi-lumen infusion unit that is mounted adjacent the catheter's distal end is positioned in an artery within a predetermined distance from a target tissue surface. An inflation balloon is then deployed to at least partially occlude the artery and a force is exerted on the liquid to establish a flow rate for the liquid in the catheter. Specifically, the force is exerted to infuse the liquid from the catheter through the infusion unit and into the vasculature with a homogeneous distribution of the liquid to cover the intended surface of the target tissue. The flow rate can be established in accordance with an infusion protocol that is characterized by time and liquid volume parameters based on viscosity and pressure values in the liquid. |
