Abstract
A fiber-optic instrument, used for ablating lesions in blood vessels, is mounted to and guided by a sleeve having two lumens extending therethrough and parallel to each other. The instrument fits within one lumen and a guidewire, previously inserted in a blood vessel, extends through the other lumen. The sleeve and instrument are advanced along the guidewire within the blood vessel. An inflatable balloon may be provided at the distal end of a fiber optic instrument for retaining saline in order to displace opaque blood that would otherwise surround the distal end of the instrument.
