摘要： Embodiments of the invention include a treatment device and corresponding treatment method for laser wound healing, the device and method making use of the simultaneous action of multiple laser types and laser wavelengths which are applied at human tissue. The treatment device generally includes a laser system and a hand-piece which is coupled to the laser system. The hand-piece is designed so that one or multiple laser beams are applied at relatively small spot and at a relatively high power level, and are surrounded by a relatively large spot of another laser beam with a relatively low power level. In a preferred implementation, the hand-piece is adapted to facilitate the emission of first and second laser beams together with a third laser beam which is delivered at a different spatial profile in comparison to the first and second laser beams.

摘要： A multiwavelength laser-based intense light source is described having applications in incision, excision and ablation of soft tissues with minimal collateral tissue damage. The light source combines the output of a plurality of relatively low power laser sources, emitting radiation in the region of the electromagnetic spectrum bounded by approximately 350 nm to 450 nm, where the combined output may be coupled into a single fiber optic energy delivery device: a standard surgical probe. Spectral and spatial beam combining are used to produce an incoherent light source with relatively low average power at any given wavelength, but with high total power and superior M2 beam quality, targeting multiple chromophores in target tissue and tissue breakdown product chromophores for consistently high and target absorption without indiscriminant char interference throughout a surgical procedure.

The treatment device comprises an emission window (70) comprising an elongated area (75) and a plurality of predefined locations (74) in said elongated area (75), wherein the predefined locations (74) are arranged in an elongated array which extends along a treatment axis (72) of the window (70), and wherein each predefined location (74) in the array is located at a distance from the treatment axis (72), seen in a direction perpendicular to the treatment axis (72), which is smaller than 25% of a maximum distance between two predefined locations (74) in the array, seen in a direction parallel to the treatment axis (72). The treatment device further comprises a treatment generator (80) comprising a treatment laser (20) for emitting laser light (21) towards skin tissue (110) from said plurality of predefined locations (74) in the emission window (70) for generating, in use, laser-based lesions (120) inside the skin tissue (110). The treatment device further comprises a motion sensor (90) for sensing motion of the treatment device relative to the skin surface (105) and a controller (60) for determining a non-zero sequence of at least one of the plurality of predefined locations in the emission window from which laser light is consecutively emitted in dependence on the sensed motion. The controller is configured to activate the treatment generator to generate said non-zero sequence when the sensed motion of the treatment device relative to the skin surface only has a component in a direction parallel to the treatment axis.

摘要： An increasing number of non-invasive skin treatment devices are being provided for use by consumers instead of by medical professionals. Such home use raises new concerns, such as safety and treatment efficacy. The invention improves on existing devices and treatment methods. The invention provides a device and method, wherein a light source is configured and arranged to provide a first (31) and a second (32) region of non-zero intensity within a transverse cross-section of a laser light beam (21) having a single higher-order laser beam mode, and a third region (33), disposed between the first (31) and second (32) regions, of lower light intensity than the non-zero light intensity. The first (31) and second (32) regions are configured to create, during use, a lesion in skin tissue in the focal spot of the laser light beam, and the third (33) region is configured to avoid creating in the focal spot, during use, a lesion in skin tissue between the lesions created by the first and second regions. For example, the light source may be configured and arranged to produce laser light in a higher mode, the order being higher than fundamental mode. The intensity pattern of the beam profile, with its regions of substantially differing intensity, is substantially constant along the propagation axis. This provides an area in the skin tissue in the focal spot at the treatment location with substantially no lesions, disposed between areas of lesions.

摘要： A method for reducing human or animal tissue includes making a plurality of excisions to collectively form a patch of tissue to be reduced, instead of making a single large excision in the patch. Thus, scarring after healing is less noticeable. The treated regions of tissue may be arranged such that a total area of all removed tissue segments taken in a direction perpendicular to an axis of the patch changes gradually along said axis. The removed regions of tissue may be navicular in shape, and the patches may be navicular in shape in the event an elongated excision is made. The removal of tissue regions can be realized by proper treatment methods such as incisions and laser treatment.
