US Patent:

6709446, Mar 23, 2004

Filed:

Jan 31, 2001

Appl. No.:

09/774084

Inventors:

Scott Lundahl - Lexington MA
Rebecca Kozodoy - Randolph MA
Ronald Carroll - Hingham MA
Elton Leppelmeier - Highland Height OH

Assignee:

Dusa Pharmaceuticals, Inc. - Toronto

International Classification:

A61N 506

US Classification:

607 88, 607 91

Abstract:

An apparatus and method for photodynamic therapy or photodynamic diagnosis using an illuminator comprising a plurality of light sources generally conforming to a contoured surface and irradiating the contoured surface with substantially uniform intensity visible light. The light sources may comprise generally U-shaped fluorescent tubes that are driven by electronic ballasts. Adjustment of the ballast voltage controls the output power of the tubes. The tubes are supported by a sheet-metal or plastic housing and are covered by a polycarbonate shield which directs cooling airflow within the unit and prevents glass-patient contact in the event of tube breakage. An aluminum reflector located behind the tubes increases both the output irradiance and the uniformity of the output distribution. The spacing of the U-shaped tubes is varied to increase the output at the edges of the illuminator to make the output more uniform. Also, different portions of the tubes are cooled at different amounts, to improve uniformity.

US Classification:

313485, 600476, 607 91

Abstract:

A method of photodynamically diagnosing or treating a contoured surface includes topically applying 5-aminolevulinic acid to the contoured surface and irradiating the contoured surface with substantially uniform intensity visible light from a plurality of light sources generally conforming to the contoured surface. The plurality of light sources may comprise fluorescent tubes.

International Classification:

A61K031/198

US Classification:

514561000, 604020000

Abstract:

Methods of enhancing the efficacy and safety of treatment with immuno-modulating agents are provided. The inventive methods combine treatment with immuno-modulating agents with photodynamic therapy (PDT). PDT can be administered before, during or after administration of the immuno-modulating agent. Combination therapy achieves at least the same efficacy as immuno-modulatory therapy in less time, with less immuno-modulating agent and fewer side-effects.
