Abstract
An intravascular catheter having an expandable region formed of hypotubes mounted on the distal end of a tubular member that is capable of delivering a drug to the artery and radial expansion and contraction by means of a control wire. Each of the hypotubes has at least one surface aperture and the lumen of each of the hypotubes is in fluid communication with a drug delivery lumen. A therapeutic drug is injected into the patient's vasculature through the apertures in the hypotubes. The catheter is particularly adapted to hold open an artery after a vascular procedure therein such as a balloon angioplasty or other types of vascular procedures, and if desired to introduce a drug to the site of the vascular procedure.
