Abstract
The present invention relates to a method of delivering drugs having e.g., anti-proliferative activity in the vascular, preferably, the cardiovascular, system locally or systematically using an at least partially drug-coated guidewire. The drug-coated guidewire, particularly an expansion member or portion thereof, is brought into contact with the target tissue or in circulation and the drugs are quickly released into the area surrounding the device in a short time after the contact step. Once the therapeutic drugs are released, they are quickly and effectively absorbed by the surrounding cells or circulation.
