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.

The present invention relates to a laser beam device outputting a multi-spot laser beam, and a laser bean hand piece. The laser beam device, according to the present invention, comprises: a light source unit which generates and emits a single-spot laser beam having a first wavelength; a laser beam oscillation unit which outputs the first wavelength single-spot laser beam emitted from the light source unit as any one of a first wavelength multi-spot laser beam and a single-spot laser beam having a second wavelength, and then outputs any one of the outputted first wavelength multi-spot laser beam and second wavelength single-spot laser beam as a second wavelength multi-spot laser beam, and an amplification unit which amplifies the second wavelength multi-spot laser beam so that the output energy of the second wavelength multi-spot laser beam outputted from the laser beam oscillation unit is relatively high output energy.

An apparatus for determining a thermal property of tissue includes a base unit with one or more energy source and at least two, preferably detachable, leads. The distal end of each lead, which is introduced into the tissue to be treated, has at least two longitudinally spaced temperature measuring elements to measure surrounding tissue temperature and at least two longitudinally spaced electrode surfaces for applying current to the tissue. Each distal end is also provided with an element which uses energy emitted by the sources of energy to heat up the surrounding tissue. The base unit has computing elements, current generating elements for generating an alternating current, and conductance determining elements for determining the tissue conductance between pairs of electrode surfaces based on the alternating current applied by the current generating elements to the tissue. Methods for using the device and leads for use in the device are also described.

An ophthalmological device and system is described that allows the simultaneous imaging of an eye using both scanning laser ophthalmoscopy (SLO) and optical coherence tomography (OCT). Further the device and system is capable of targeting and delivering a femtosecond treatment laser for treatment of an eye condition. The system further includes a machine learning algorithm to provide a suggested treatment procedure.

A surgical laser system includes an array of laser diodes that are configured to output laser energy, a fiber bundle, a delivery fiber, and a tubular sheath. The fiber bundle includes a plurality of optical fibers and has a proximal end that is configured to receive laser energy from the array of laser diodes. The delivery fiber includes a proximal end that is configured to receive laser energy from a distal end of the fiber bundle. The tubular sheath defines a lumen, in which at least a portion of the delivery fiber is disposed. The tubular sheath is insertable into a working channel of an endoscope or a cystoscope. A distal end of the tubular sheath is configured to deliver laser energy discharged from the delivery fiber into a body of a patient.

Multi-fiber laser probes utilize relative motion of fibers and other laser probe elements to preserve small-gauge compatibility while providing for multi-spot beam deliver, or to provide for the selectively delivery of single-spot or multi-spot beam patterns. An example probe includes fibers having distal ends that are movable as a group onto a distal ramp element affixed to a distal end of a cannula, so that the distal ends of the fibers can be moved between a retracted position, in which the distal ends of the fibers are within the cannula or ramp element, and an extended position, in which distal ends of the fibers are guided by grooves or channels of the ramp so as to extend at least partially through external openings in the distal end of the laser probe and so as to be pointed angularly away from a longitudinal axis of the cannula.

A device to remove unwanted hair on a target area (109) includes a LED unit (201), which comprises at least two types of LEDs to emitting two or more spectrum; a skin type detector (102), which comprises a light source (103) and a photoreceptor (104); and a LED driver (101), which communicates with the skin type detector (102) to sending and receiving signal, and further powers the LED unit (201) with a plurality of separate output channels. A method for removing hair using the device is also provided.

Certain aspects of the present disclosure provide a probe comprising a tube, wherein one or more optical fibers extend at least partially through the tube for transmitting at least one of a laser light and an illumination light from a light source to a target location. A distal end of the tube comprises a flat-walled morphology, and a protective window with a round edge is press-fit to the distal end. The flat-walled morphology of the distal end of the tube has a reduced diametric interference sensitivity, thus allowing a wider range of tolerances between the window and the tube walls for effective press-fitting.

The present invention relates to the field of optical imaging and therapeutics. More particularly, embodiments of the present invention provide minimally-invasive Fiberoptic Microneedle Devices (FMDs) for light-based therapeutics, which physically penetrate tissue and deliver light directly into the target area below the skin surface. Embodiments of the invention enable depth-selective and deep photothermal therapeutics and include methods of treating cancer, methods of re-shaping or removing adipose tissue, and methods of delivering drugs or co-delivering drugs and energy to selected tissue.
