Abstract
An intravascular drug delivery balloon catheter incorporating a highly compliant balloon having a plurality of infusion holes. The highly compliant balloon elastically expands at a low inflation pressure (e.g., less than 1.0 ATM), and preferably has a compliance of 2.0 mm/ATM or more at pressures less than 2.0 ATM. A pressure relief valve may be incorporated into the catheter to avoid over pressurization. The infusion holes may be open when the balloon is deflated and may enlarge when the balloon is inflated. The balloon may define a single lobe or two inflatable lobes with the infusion holes disposed therebetween.
