Publication number: 20210085788Abstract: A method of enhancing penetration of a topical composition of 5-aminolevulinic acid (ALA) into tissue for photodynamic therapy includes topically applying ALA to a treatment area to be treated with photodynamic therapy. The method further includes, after the ALA is applied to the treatment area, covering the treatment area with a low density polyethylene barrier. The treatment area is covered with the low density polyethylene barrier prior to light treatment to minimize transepidermal water loss from the treatment area.Type: ApplicationFiled: December 2, 2020Publication date: March 25, 2021Applicant: DUSA Pharmaceuticals, Inc.Inventors: Scott LUNDAHL, Michael GUTTADAURO

Publication number: 20210001101Abstract: An applicator for dispensing a solution having two or more components includes a hollow body having a head provided at one end of the hollow body for dispersion of the solution and a breaking mechanism attached to the hollow body. The breaking mechanism includes at least one projection extendable into an interior of the hollow body. The applicator further includes a plurality of ampoules placed in the interior of the hollow body. The plurality of ampoules contains the two or more components. Upon activation of the breaking mechanism, the at least one projection applies a force to the plurality of ampoules such that the plurality of ampoules break and release the two or more components to form the solution.Type: ApplicationFiled: September 22, 2020Publication date: January 7, 2021Applicant: DUSA Pharmaceuticals, Inc.Inventors: Thomas BOYAJIAN, Mark CAROTA

Publication number: 20200398071Abstract: A method of administering 5-aminolevulinic acid (ALA) to a patient uses an adjustable illuminator for photodynamically diagnosing or treating a surface and which includes a plurality of first panels and at least one second panel. The plurality of first panels have wider widths and the at least one second panel has a narrower width. The narrower width is less than the wider widths. The illuminator further includes a plurality of light sources, each mounted to one of the plurality of first panels or the at least one second panel and configured to irradiate the surface with substantially uniform intensity visible light. The plurality of first panels and the at least one second panel are rotatably connected. The at least one second panel is connected on each side to one of the plurality of first panels. The second panel acts as a “lighted hinge” to reduce or eliminate optical dead spaces between adjacent panels when the illuminator is bent into a certain configuration.Type: ApplicationFiled: September 2, 2020Publication date: December 24, 2020Applicant: DUSA Pharmaceuticals, Inc.Inventors: Thomas BOYAJIAN, Mark CAROTA, Brian MAZEJKA

Patent number: 9723991Abstract: 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. 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. A light sensor monitors output from the U-shaped tubes to provide a signal for adjusting the output from the tubes.Type: GrantFiled: May 20, 2014Date of Patent: August 8, 2017Assignee: DUSA PHARMACEUTICALS, INC.Inventors: Scott Lundahl, Rebecca Kozodoy, Ronald Carroll, Elton Leppelmeier
