A dilation-drug delivery catheter comprises a dilation portion for dilating a stenosis and a drug delivery portion for delivering antithrombolytic, antiproliferative, or any other type of medication, to the dilation site. The drug delivery portion of the catheter is located within the dilation portion, which can be retracted to reveal the drug delivery portion, after dilation. Occlusion balloons are preferably provided on the drug delivery portion to isolate the dilation site during drug delivery.
