Patent ID: 7976571

Claim:
A photo dynamic therapy laser delivery system for the safe delivery of laser radiation to an area of treatment below a layer of skin comprising: a plate with a plurality of spaced openings, said plate having a treatment side and an insertion side, said spaced openings connecting said sides; micro-needles placed in the said spaced openings; first means for holding said micro-needles in said spaced openings in said plate; wherein said micro-needles extend beyond said treatment side, by a predetermined distance sufficient to penetrate through the skin; second means for holding said plate on said layer of skin; optical fibers placed in at least two of said micro-needles; third means for positioning said optical fibers in said micro-needles; wherein said optical fibers have proximal ends and distal ends, said proximal ends being connected to a source of laser radiation, and said distal ends having-output-devices, being positioned in said area of treatment; and wherein said distal end has a diffuser thereon to enable even distribution of said laser radiation in target tissue.
