System and method for generating patterns P of aiming and treatment light on target eye tissue (e.g. the retina) of a patient's eye. The system includes light sources for treatment and aiming light, a scanner for generating patterns of spots of the generated light, a controller, and a graphic user interface that allows the user to select one of several possible spot patterns, adjust the spot density and/or spot size, and apply patterns with fixed or varied density. The patterns can be formed of interlaced sub-patterns and/or scanned without adjacent spots being consecutively formed to reduce localized heating. Partially or fully enclosed exclusion zones within the patterns protect sensitive target tissue from exposure to the light.

A skin treatment laser apparatus using complex radiations with different pulse durations according to the present invention comprises: a laser generation device for modulating at least one reference laser ray into multiple laser rays having different energy magnitudes and pulse durations, and alternating multiple laser rays so as to repeatedly output the alternated laser rays; and a laser irradiation device for irradiating a skin lesion with the multiple laser rays are alternated to be repeatedly applied by the laser generation device, so that laser ays having different pulse durations can be alternately and repeatedly irradiated onto a skin lesion for a laser irradiation period of time according to a chromophore, thereby improving the efficiency of laser treatment.

In combined methods for treating a patient using time-varying magnetic field, treatment methods combine various approaches for aesthetic treatment. A magnetic field generating device is placed proximate to a body region of the patient. The magnetic field generating device generates a time-varying magnetic field with a magnetic flux density in a range of 0.5 to 7 Tesla. The time-varying magnetic field is applied to the body region of the patient in order to cause a contraction of a muscle within the body region. A second therapy may be used by applying one or more of optical waves, radio frequency waves, mechanical waves, negative or positive pressure or heat to the body region of the patient.

The medical device may include a shaft having a distal end, and a cap at the distal end of the shaft. The cap may include a lens and a reflector for deflecting the laser energy toward the lens. The lens may be configured to emit the laser energy from the cap toward a target.

The present invention provides a laser system and laser handpiece and process for skin treatment. The system includes components for producing a continuous or pulse laser beam, and components for delivering a substance to the damaged region of skin. The system is designed to control and utilize the laser beam for damaging small volume of skin tissue and using a disposable tip to deliver a substance which is applied simultaneously or with some delay producing a combination of laser action with the action of a named substance at the same time.

The present disclosure enables improved laser treatments by enabling better estimation of laser-tissue interaction to better inform the planning of a treatment path for a laser signal through a treatment region. An embodiment in accordance with the present disclosure uses a laser signal to generate a feature in the treatment region, generates a surface profile of the treatment region that includes the feature, compares that surface profile to another surface profile of the treatment region taken before the generation of the feature, and infers at least one property for at least one tissue type in the treatment region based on the comparison. In some embodiments, the feature is generated such that it includes a plurality of tissue types previously identified in the treatment region, thereby enabling inference one or more properties for each tissue type and/or locating one or more boundaries between tissue types.
