Abstract
Phototherapeutic instruments are disclosed for providing substantially uniform energy distribution to a major portion of an area exposed during phototherapy. These instruments include an element for directing radiation toward the walls of a lumen and a device for centering the radiation directing element within the lumen. The instruments also allow the flow of blood, therapeutic fluid, or air past the exposure site. The instruments are particularly useful as part of a fiber optic-based medical laser system for photodynamic therapy within the bronchia of the lung, blood vessels or other liquid-filled lumens.
