Abstract
An intravascular catheter with an expandable region formed of a tubular material that continues the distal end of the catheter body in a one-piece configuration and is radially expanded and contracted by means of a control wire. The interior of the expandable region is in fluid communication with a lumen in the catheter body to allow the delivery of a fluid to the artery via openings in the surface of the expandable region. The catheter is particularly adapted to hold open an artery after a vascular procedure therein such as a balloon or other type of angioplasty, and if desired to introduce a therapeutic drug or other fluid to the site of the vascular procedure.
