Abstract
A therapeutic light delivery apparatus and method are disclosed. The apparatus includes a light source and an integrated optical applicator. The integrated optical applicator includes a plurality of light emitting devices and detector fibers fixedly spatially positioned within a flexible matrix material. The light emitting devices can be positioned a predetermined distance from an application side of the integrated optical applicator comprising an accurate and repeatable standoff position. A flexible matrix material is disclosed having a high scattering coefficient to produce a uniform irradiance pattern and predetermined fluence. A method of performing a photodynamic therapy procedure is disclosed that includes providing an integrated optical applicator couple to a therapy light source, providing a photosensitizing drug to a tissue of a patient, positioning an application side of the integrated optical applicator against a target area of the tissue, delivering a therapy light to the target area, and producing an irradiance pattern.
