Method and device for the superficial heating of tissue
First Claim
1. A method for the superficial heating of tissue with the aid of a pulsed light source, in which method a series of light pulses are applied to the surface of the tissue, wherein a light source with a wavelength of which the light is absorbed mainly in the region at the surface of the skin which lies above a tissue depth of 50 μ
- m is used, wherein a first part of the series of light pulses is configured such that rapid heating of the surface of the skin and then, after a time delay, heating of regions of tissue lying beneath this region of the surface of the skin to a prescribed target temperature is achieved by heat conduction without tissue removal, and wherein a subsequent part of the series brings about an oscillation of the temperature of the regions of tissue about a value lying slightly below the target temperature.

Abstract
The invention relates to a method and a device for the superficial heating of tissue by means of a pulsed light source. According to the invention a series of light pulses is applied to the tissue surface. The first part of this series is configured such that the tissue surface and, by heat conduction, tissue areas situated below the tissue surface are rapidly heated to a defined target temperature without tissue removal. The subsequent part of the series results in oscillation of the temperature of the tissue areas located below the tissue surface around a value which is slightly lower than the target temperature.

9. A device for the superficial heating of biological tissue, with a light source which can be activated in a pulsed manner and a control unit for controlling the light source, which activates the light source in such a way that series of light pulses each of a prescribed duration and irradiation intensity are supplied, wherein the light source supplies light pulses of such a wavelength that the light pulses are mainly absorbed in a region at the surface of the skin which lies above a tissue depth of 50 μ
- m, wherein each series comprises a first part, which brings about rapid heating of this region of the surface of the skin and then, after a time delay, heating of regions of tissue lying beneath this region of the surface of the skin by heat conduction to a prescribed target temperature, which lies below the temperature at which the tissue removal occurs, and a subsequent part, which brings about an oscillation of the temperature of the surface of the skin and/or of the region of tissue lying beneath the surface of the skin about the target temperature, this temperature likewise lying below a temperature inducing removal.
