ABSTRACT:
A method for contemporaneously applying laser energy and locally delivering pharmacologic therapy to a selected site in a body lumen using a liquid core or fiber optic laser catheter or angioscope. The method comprises preparing a solution of a pharmacologic agent, inserting the catheter into the lumen, directing the catheter to the site, transmitting visible light to the site, flowing the light transmissive liquid through the catheter to the site to be treated, positioning an emission end of the fiber near (.+-.2 mm) the distal end of the catheter, transmitting laser energy through the fiber to be emitted at the emission end of the fiber into the liquid to treat the site, and introducing a flow of the pharmacologic agent in solution into the catheter for contemporaneous discharge at the distal end into the lumen adjacent the site.
