摘要:
The present invention provides improved methods and apparatus for skin treatment and tissue remodeling. The apparatus includes an array of needles that penetrate the skin and serve as electrodes to deliver radio frequency current or other electrical or optical energy into the tissue being treated, causing thermal damage in controlled patterns. The damaged regions promote beneficial results such as uniform skin tightening by stimulation of wound healing and collagen growth.

The present invention relates to methods for use in the selective disruption of lipid-rich cells by controlled cooling. The present invention further relates to a device for use in carrying out the methods for selective disruption of lipid-rich cells by controlled cooling.
摘要:
The present invention provides improved methods and apparatus for skin treatment. The apparatus includes multiple sources of optical energy or several blades that are scanned along a region of skin to form micro-line patterns of damaged tissue. The micro-lines are small in at least one dimension, having a width of less than about 1 mm, and the wounded regions promote beneficial results by stimulation of wound healing and tissue remodeling.
摘要:
A method and apparatus are provided for performing a therapeutic treatment on a patient's skin by concentrating applied radiation of at least one selected wavelength at a plurality of selected, three-dimensionally located, treatment portions, which treatment portions are within non-treatment portions. The ratio of treatment portions to the total volume may vary from 0.1% to 90%, but is preferably less than 50%. Various techniques, including wavelength, may be utilized to control the depth to which radiation is concentrated and suitable optical systems may be provided to concentrate applied radiation in parallel or in series for selected combinations of one or more treatment portions.
摘要:
The present invention encompasses methods that use heat and/or electromagnetic radiation for dermatological treatment and more particularly to a method that uses heat and/or electromagnetic radiation in combination with chromophores for fractional wounding and, in particular, discontinuous fractional damage of skin tissue.
摘要:
A method and apparatus are provided for treating dermatological conditions, in which a first beam of radiation is used to ablate a hole in skin tissue, and a second beam of radiation is directed into the hole and onto a region of skin tissue adjacent to and/or at the bottom of the hole. The first beam can be provided by an ablative laser such as a CO2 laser or an ER:YAG laser. The second beam can be provided by, e.g., an ablative laser operating at a lower peak power level than the first beam, a non-ablative laser, a flashlamp, a tungsten lamp, a diode or a diode array. A controlled amount of thermal damage can thereby be provided at a desired depth within the skin, using radiation sources that would be absorbed closer to the surface of the skin if an ablated hole were not present. Cooling and/or freezing of the skin prior to ablation can be provided to provide an analgesic effect and/or stabilize the tissue surrounding the ablated hole. The region of skin to be treated can optionally be pulled towards the radiation source using a vacuum to stretch and/or stabilize the skin tissue surrounding the volume to be ablated.

摘要:
Exemplary embodiments of an apparatus can be provided for obtaining portions or samples of tissue from a target region of a biological tissue. One or more needles can be provided that have a small internal diameter, e.g., about 1 mm or less, and the needles can be configured to extract the tissue portions when the needles are inserted into and withdrawn from the tissue. Windows and/or markings can be provided on the wall of the needles to facilitate access to the sample. The needles can be provided in an enclosure, and an actuator can be provided to direct the needles into the tissue and/or withdraw them. A plurality of tissue portions having known relative locations in the target region can be obtained, and extraction of the tissue portions can be well-tolerated by the tissue as compared with conventional punch biopsies or the like.
摘要:
Exemplary embodiments of a method, device, and apparatus for positioning an apparatus on a location of a tissue. For example, a substantially rigid film over an area of tissue to be treated can be provided. The film can include a positioning arrangement that facilitates a particular spatial engagement with the apparatus. The exemplary method can further include applying a portion of the film to a portion of a surface of the tissue and positioning the apparatus at the location by the engagement of the film to the apparatus using the feature of the film.
