Abstract
A method of simultaneous angioplasty and drug delivery to a localized portion of coronary or peripheral arteries or any other type of body passage that has a stricture. The invention contemplates positioning a drug delivery device in a body passageway and then selectively introducing a selected drug so that the device is expanded in order to dilate the passage and then simultaneously causing the drug to be transported across a drug transport wall of the device for direct contact with the passageway wall. A more specific aspect of the present invention involves treating a dilated vessel in the area of a stenotic lesion with a fixative or other drug to render the vessel biologically inert and to form a biological stent or prevent restenosis using specifically selected drugs.
