20100067081 | Optical Pattern Generator Using a Single Rotating Component - An optical pattern uses a single rotating component. The rotating component includes a number of deflection sectors. Each sector deflects an incident optical beam by a substantially constant angular amount although this amount may vary from one sector to the next. The rotating component may be combined with an imaging lens group that produces, for example, image points, spots, or lines displaced along a line locus. | 03-18-2010 |
20110087201 | APPARATUS AND METHOD FOR ADJUSTABLE FRACTIONAL OPTICAL DERMATOLOGICAL TREATMENT - A fractional treatment system can be configured with a laser wavelength that is selected such that absorption of the laser wavelength within the tissue increases as the tissue is heated by the laser (e.g., 1390-1425 nm). Desirably, the laser wavelength is primarily absorbed within a treated region of skin by water and has a thermally adjusted absorption coefficient within the range of about 8 cm | 04-14-2011 |
20110098691 | Apparatus and Method for Adjustable Fractional Optical Dermatological Treatment - In a fractional treatment system, an adjustable mechanism can be used to adjust the beam shape, beam numerical aperture, beam focus depth, and/or beam size to affect the treatment depth and or the character of the resulting lesions. Adjustment of these parameters can improve the efficiency and efficacy of treatment. Illustrative examples of adjustable mechanisms include a set of spacers of different lengths, a rotatable turret with lens elements of different focal distances, an optical zoom lens, and a mechanical adjustment apparatus for adjusting the spacing between two optical lens elements. In one aspect, the fractional treatment is configured with a laser wavelength that is selected such that absorption of the laser wavelength within the tissue decreases as the tissue is heated by the laser (e.g., 1480-1640 nm). Desirably, the laser wavelength is primarily absorbed within a treated region of skin by water and has a thermally adjusted absorption coefficient within the range of about 7 cm | 04-28-2011 |

20120238941 | Treatment of Alopecia By Micropore Delivery of Stem Cells - A method of restoring hair to skin that has suffered hair loss includes optically ablating an array of spaced-apart microchannels or voids into the skin and transplanting into the voids stem cells, a scaffold and a differentiation factor for causing the stem cells to differentiate into hair follicles. | 09-20-2012 |
20130310817 | DEVICES AND METHODS FOR TISSUE TREATMENT ACROSS A LARGE SURFACE AREA - Light sources and methods for spreading a beam of electromagnetic radiation. The light sources include a scattering element with an outlet and an angular-selective element with an inlet spatially disposed between the outlet of the scattering element and an electromagnetic radiation source. The beam enters the inlet traveling in a direction of propagation and propagates through the beam spreader to the outlet for transmission from the outlet. The scattering element includes a scattering medium configured to scatter the electromagnetic radiation in the beam to provide a two-dimensional spatial distribution for intensity that is substantially uniformly across the outlet. The angular-selective element is configured to reflect a majority of the electromagnetic radiation of the first beam scattered by the scattering medium in a direction opposite to the propagation direction and reaching the angular-selective element. | 11-21-2013 |

20080208178 | Method and Apparatus for Monitoring and Controlling Laser-Induced Tissue Treatment - The present invention provides improved methods and apparatus for controlling light-induced tissue treatment. In accordance with various aspects of the present invention, the invention provides for improved, real-time control of the light beam operational parameters which enables greater safety, efficiency, uniformity and continuity of the treatment process. | 08-28-2008 |
20080208179 | METHODS OF INCREASING SKIN PERMEABILITY BY TREATMENT WITH ELECTROMAGNETIC RADIATION - Methods of treating tissue with fractional laser radiation are disclosed. The fractional laser treatment methods reversibly increase skin permeability while maintaining a substantially intact stratum corneum and producing alterations within the epidermis and dermis. The alterations in the epidermis and dermis can include necrosis and/or coagulation. The alterations in the epidermis can include the creation of a plurality of pores in the stratum corneum and/or the creation of vacuoles in the layers of the epidermis below the stratum corneum. The fractional laser treatment methods disclosed herein can be used to provide treatments to the skin, to increase permeation of active substances into or through tissue, to deliver active substances locally or systemically, and to control the delivery of active substances. | 08-28-2008 |

The delivery system can be configured to receive ablative energy from the electromagnetic source and deliver it to multiple discrete locations at the selected region to form a pattern of discrete holes in epidermal and dermal tissue of the skin. The lipid content a portion of the tissue can be evaluated using a sensing element. At least one pulse of electromagnetic energy is delivered to the skin under control of a controller in response to the result of a measurement by the sensing element. The apparatus may include a positional sensor to provide additional dosage control, particularly when the inventive method is used with a continuously movable handpiece. | 12-24-2009 |
