Abstract
The present invention provides single balloon infusion catheters that provide an infusion chamber between a body lumen and the catheter balloon when the catheter balloon is inflated. High concentrations of pharmaceutical formulations and other liquids and solutions can be delivered into the infusion chamber under low pressure for local infusion therapy. Optionally, the catheters permit fluids such as blood to continue flowing through the body lumen during infusion therapy.
