Publication number: 20140277299Abstract: An apparatus for applying targeted phototherapy to a skin treatment area includes a UVB module arranged to output light at about 308 nm having at least one flash lamp arranged to generate light including UVB light and a UVB transmissive window for transmitting UVB light generated by the flash lamp, a user interface, and a controller configured to detect when the user interface is actuated and to cause pulsing of the flash lamp in response to the actuation of the user interface. A method of applying targeted phototherapy to a skin treatment area includes contacting a phototherapy apparatus with the skin, the apparatus including at least one flash lamp and a UVB transmissive window, such that the window is positioned in alignment with the treatment area, and activating the flash lamp to cause pulsed UVB light at 308 nm to be transmitted through the window.Type: ApplicationFiled: March 13, 2014Publication date: September 18, 2014Applicant: PHOTOMEDEX, INC.Inventors: Alfred J.

Patent number: 8746253Abstract: Skin disorders such as, for example, atopic dermatitis, dyshidrosis, eczema, lichen planus, psoriasis, and vitiligo, are treated by applying high doses of ultraviolet light to diseased regions of a patient's skin. The dosage exceeds 1 MED as determined for the particular patient and may range from about 1 MED to about 20 MED or higher. The ultraviolet light has a wavelength within the range of about 295 nanometers to about 320 nanometers. High doses of ultraviolet light are preferably restricted to diseased tissue areas. A specialized handpiece provides a beam profile especially suitable for application of controlled doses. A specialized delivery device is useful for UV treatment of tissue within the mouth.Type: GrantFiled: September 14, 2012Date of Patent: June 10, 2014Assignee: PhotomedexInventor: Dean S. Irwin

Patent number: 8486056Abstract: Skin disorders such as, for example, atopic dermatitis, dyshidrosis, eczema, lichen planus, psoriasis, and vitiligo, are treated by applying high doses of ultraviolet light to diseased regions of a patients skin. The dosage employed exceeds 1 MED, an MED being determined for the particular patient being treated, and may range from about 1 MED to about 20 MED or higher. The ultraviolet light has a wavelength within the range of between about 295 nanometers to about 320 nanometers and preferably is between about 300 nanometers and about 310 nanometers. High doses of ultraviolet light are restricted to diseased tissue areas so as to avoid risk of detrimental side affects in healthy skin, which is more susceptible to damage from UV light. Cooling the skin prior to and/or while exposing the skin to the UV light can be used to minimize tissue damage resulting from exposure to the UV light. Higher doses of UV light can therefore be employed without injurious affects.Type: GrantFiled: March 3, 2010Date of Patent: July 16, 2013Assignee: PhotomedexInventor: Dean S. Irwin
