Publication number: 20110015549Abstract: A diseased nail is treated using electromagnetic radiation and/or other forms of energy that are applied to the diseased area to eliminate, substantially eliminate or effectively reduce the source of disease in the nail. A sensor can be used to ensure proper placement of an applicator that applies the energy to the diseased area of the nail. A temperature monitor can be employed to monitor changes or temperature levels and then adjust the energy application accordingly. In additional, manual forms of adjustment can be used to control the application of energy.Type: ApplicationFiled: September 28, 2010Publication date: January 20, 2011Inventors: Shimon Eckhouse, Tuvia Dror Kutscher, James C.

Publication number: 20080269733Abstract: A method for treating wrinkles in skin involves the use of a beam of pulsed, scanned or gated continuous wave laser or incoherent radiation. The method comprises generating a beam of radiation, directing the beam of radiation to a targeted dermal region between 100 microns and 1.2 millimeters below a wrinkle in the skin, and thermally injuring collagen in the targeted dermal region. The beam of radiation has a wavelength of between 1.3 and 1.8 microns. The method may include cooling an area of the skin above the targeted dermal region while partially denaturing the collagen in the targeted dermal region. The method may also include cooling an area of the skin above the targeted dermal region prior to thermally injuring collagen in the targeted dermal region.Type: ApplicationFiled: July 3, 2008Publication date: October 30, 2008Inventors: R.

Publication number: 20080269735Abstract: An apparatus can treat biological tissue using a base member, a plurality of needles, and a plurality of fiber optics. The plurality of needles extend from the base member. Each needle defines a bore capable of receiving a fiber optic and has an end. The plurality of needles form an array capable of penetrating a biological tissue and positioning each end within a subsurface volume of the biological tissue. Each fiber optic is adapted for insertion into the bore of each needle, and each fiber optic is capable of delivering electromagnetic radiation to the subsurface volume of the biological tissue to treat the biological tissue.Type: ApplicationFiled: April 26, 2007Publication date: October 30, 2008Inventors: Agustina Vila Echague, Jayant D.

Publication number: 20080269734Abstract: Skin can be treated by penetrating an epidermis of the skin with a plurality of waveguides. Each waveguide has an end, which is positioned within a dermis of the skin. Electromagnetic radiation can be delivered through the plurality of waveguides to the dermis having a port wine stain for a time sufficient to selectively destroy a cutaneous blood vessel within the port wine stain. The time is less than a thermal diffusion time between the epidermis and the dermis to prevent forming substantial unwanted thermal injury within the epidermis.Type: ApplicationFiled: June 1, 2007Publication date: October 30, 2008Inventors: Agustina Vila Echague, Jayant D.
