摘要:
Tissue is treated by irradiating it with a sequence of optical pulses that are directed in sequence to various sites on the tissue. During the irradiation sequence, one or more tissue properties are measured at a site(s) that has already been irradiated. These measurements are used to adjust the parameters of subsequent optical pulses in the sequence.

An optical pattern generator uses a rotating component that includes a number of deflection sectors containing optical elements. Each sector deflects an incident optical beam by a substantially constant angle although this angle may vary from one sector to the next. The constant deflection angle is achieved by symmetry within the deflection sector, specifically gut-ray symmetry. The rotating component may be combined with an imaging group that produces, for example, image points, spots, or lines displaced along a line locus. The image spots can also be displaced to either side of a line, for example by introducing a tilt in the orthogonal direction or by introducing light beams at various angles to the plane of symmetry.

Methods and devices for treatment of tissue which first apply a nonablative form of electromagnetic energy to a region of tissue to create a plurality of treatment zones containing coagulated tissue and subsequently apply an ablative form of electromagnetic energy to the coagulated tissue in the treatment zones in order to ablate the coagulated tissue are disclosed. These methods and devices can be used to shrink and/or tighten tissue for medical and cosmetic purposes.

An optical pattern generator includes one or more multi-faceted rotating optical elements that introduce an offset that is rotation insensitive. The component that generates the offset is rotationally symmetric around the rotational axis of the optical element. Thus, as the optical element rotates, the effect of the offset component does not change. In addition, rotating optical elements may be designed to counteract unwanted optical effects of each other.

The invention describes a treatment for skin wherein a pattern of holes is ablated in a selected region of skin tissue using an optical source. Substantially nonablative energy is delivered to the selected region to at least two holes in the pattern to thermally heat a target in or just beneath the skin, such as hair follicles, sebaceous glands, or subcutaneous fat. The invention may further be improved by adding a feedback mechanism that adapts the nonablative energy in response to a measurement enabled by the ablation of holes. The apparatus may include a positional sensor to provide additional dosage control, particularly when the inventive method is used with a continuously movable handpiece.

The present invention relates to a method and apparatus for using an imaging detector to image an optical pattern created by illumination of a viscous material that is applied to the skin. The viscous material forms a detectable pattern that can be imaged by the imaging detector. In some examples, the viscous material is reflective and allows reflection from an illumination source to create an optical pattern on the imaging detector. In other cases, the variation in thickness of an absorbing or scattering viscous substance can be imaged by the detector. Polarized illumination and detection can be used to enhance the response.
