Patent number: 8870856Abstract: A system and method for using a light source to treat tissue with NIR light. The operation provides for generating higher temperatures in deeper layers of tissue relative to higher layers of tissue. The increased temperature in dermal layers can operate to induce collagen shrinkage, or remodeling. One of the light sources for providing a broad spectrum of NIR light is a filament light. The light from the filament lamp can be selectively filtered, and after filtering this light is applied to the skin, where the selective filtering can enhance the ability to elevate the temperature of deeper layers of tissue, relative to layers of tissue which are closer to the surface of the skin.Type: GrantFiled: February 27, 2004Date of Patent: October 28, 2014Assignee: Cutera, Inc.Inventors: Kevin P.

Patent number: 8571648Abstract: Methods and apparatuses to apply substances to a biological tissue are described. The tissue having an target below a surface is stretched to provide openings in a surface. Stretching forces a material from the target onto the surface. A first substance may be applied while stretching to promote cleaning the tissue. A second substance may be applied to the surface. Energy may be applied to the tissue. Then the tissue is relaxed to draw the second substance through the openings into the tissue. The tissue may be stretched by applying a negative pressure, and relaxed by removing the negative pressure. The first substance may be an abrasive material. The second substance is a medicine, a moisturizer, a lotion, or any combination thereof. The second substance may be applied to the biological tissue using a positive pressure. The apparatus to apply substances may be a handheld device.Type: GrantFiled: May 6, 2005Date of Patent: October 29, 2013Assignee: AestheraInventors: Robert S. Anderson, Steve Young
