A probe of a target identification system can be extended via a first lumen of a viewing instrument, such as for illuminating an area beyond a distal end of the viewing instrument via an optical path of the viewing instrument. An optical response to the illumination of the area can be received via an optical path of the probe and can be split from other optical signals of the optical path. The optical response information can be used to identify characteristics of a target and to adjust parameters of a working instrument such as a working instrument contemporaneously using the probe.

An apparatus for microdisruption of cataracts in lens tissue by impulsive heat deposition comprising: a source of pulsed laser radiation, a user input device, a control circuit, and an optical waveguide configured to transmit the pulsed laser radiation. The light intensity which exits the optical waveguide has a wavelength selected to match an absorption peak of at least one component of the lens tissue, a pulse duration time shorter than a time required for thermal diffusion out of the laser irradiation volume and shorter than a time required for a thermally driven expansion of the laser irradiated volume, and a pulse energy resulting in a peak intensity of each laser pulse below a threshold for ionization-driven ablation to occur.

A laser device for dermocosmetic, medical, or aesthetic treatments, comprising: A) a laser system comprising a lamp-pumped source; B) an optical fibre transporting the laser beam produced by said source; C) a handpiece or a scanner connected to said optical fibre, comprising a lens and mirror system projecting the image of the laser beam onto the area to be treated; characterized in that said optical fibre has a rectangular section and said image is rectangular.

A light measurement device measures the intensity of laser light output from a catheter tip end portion of a catheter having a built-in optical fiber. The light measurement device includes a light receiving part which receives the laser light output from the catheter tip end portion and a mounting part which is disposed at a position facing the light receiving part. The mounting part defines a position of a tubular hoop, which accommodates the catheter, with respect to the light receiving part. In a state in which the position of the hoop is defined by the mounting part, the light measurement device obtains the intensity of the laser light by inputting the laser light to the light receiving part.

Various methods, systems, and devices for treating tissue ablation are disclosed. Some embodiments disclosed herein pertain to methods of treating tumors, systems used for irradiating tissue and tumors with electromagnetic radiation, components and devices of that system, and kits for providing systems used for irradiating tissue and tumors with electromagnetic radiation. In some embodiments, the system provides sub-ablative infrared radiation that is absorbed by nanoparticles. In some embodiments, the nanoparticles absorb the radiation converting it into heat energy. In some embodiments, though the infrared radiation itself may be sub-ablative, the heat energy generated by the nanoparticles is sufficient to cause thermal coagulation, hyperthermia, and/or tissue ablation.

A laser therapeutic device for a laser endoscope capable of relatively reducing the diameter of the endoscope while being capable of emitting a laser beam of a uniform intensity over a wide area is provided. An optical guide element (a square-shaped rod lens 15, a guide tube 2b) having a quadrangular cross section and guiding a therapeutic laser beam emitted from the tip of an optical fiber toward the tip side of a probe is used. On the tip side of a probe tube 2 being a barrel, using clearances C1 to C4 formed between the optical guide element and the inner circumferential surface of the probe tube, a camera unit 11 as imaging means and white-color LED units 12 and an ultraviolet LED unit 13 as illumination means are arranged.

The invention relates to combined liposuction methods and can be used in surgical interventions to remove local fat deposits in the lower third of the face and neck. The method includes a preoperative examination of the patient when one or more areas of the lower third of the face and neck of the patient are designated as liposuction areas constituting the operative field. The contour boundaries of the operative field and at least one operative access point are determined. Uniform infiltration anesthesia of the adipose tissue to be removed in the liposuction areas is performed. From a Nd:YAG laser radiation source with a wavelength of 1064 nm, a Nd:YAG laser radiation with a wavelength of 1064 nm in a pulsed mode with a frequency of 50 Hz, with a pulse duration of 300 s and a power of the predetermined value is supplied directly to the adipose tissue to be removed.
