ABSTRACT:
A catheter device for treating a vascular disease is provided. The catheter device includes an energy delivery device such as an optical fiber for delivering laser energy and a catheter. The catheter lumen receives the optical fiber and a fluid such as an anesthetic agent or vasoconstricting agent. According to the invention, a plurality of exits are formed in the sidewall of the catheter. The exits are in communication with the catheter lumen and administer the fluid into the blood vessel. By administering the fluid from within the catheter lumen, the present catheter device eliminates the need to make numerous external punctures to deliver fluid injections.
