Abstract
Apparatus for delivering fluids to blood vessels, body cavities and the like, includes a resilient tubular wire for threading lengthwise into the lumen of a catheter and out the distal end thereof to a target location of a body passageway to be treated. The tubular wire has a central lumen and a distal end formed into a coil, which, when straightened, may be threaded lengthwise through the catheter, but when extended out the distal end of the catheter at the target location, resumes its coiled shape. The tubular wire includes openings at least on the outside of the coils for discharging radially outwardly medication carried in the lumen of the wire. In this manner, the medication may be directed toward the wall of the passageway to infuse a diseased area being treated.
