ABSTRACT:
A two-pulse, lateral tissue illuminator in which a first pulse delivered by a first optical waveguide is used to irradiate a liquid-containing region to form a vapor bubble; a second pulse, delivered by a second optical waveguide, is then passed through the vapor bubble and used to incise a tissue of a patient. The illuminating device can be used to effectively deliver radiation to tissue positioned laterally relative to the axis of the delivery fibers, and allows a reduction in the attenuation of the radiation by the surrounding liquid.
