Treatment systems, methods, and apparatuses for improving the appearance of skin or other target regions are described. Aspects of the technology are directed to improving the appearance of skin by tightening the skin, improving skin tone or texture, eliminating or reducing wrinkles, increasing skin smoothness, or improving the appearance sites with cellulite. Treatments can include cooling a surface of a patient's skin and detecting freezing in the cooled skin. The tissue can be cooled after the freeze event is detected so to maintain the frozen state of the tissue to improve the appearance of the treatment site.

Some embodiments are directed to a cellulite treatment system that contains a laser generating device. A hydrogel patch may include a region, at a first side of the hydrogel patch, to be in contact with a person's skin. The region may contain an adsorbing medium (e.g., carbon black or any other substance that would have a similar effect) that, when receiving a laser beam from the laser generating device, results in Extracorporeal Shock Wave Therapy (“ESWT”) being applied to the person's skin to treat cellulite.

A treatment apparatus includes a motorized subsystem in a handpiece housing having a rotating output shaft, an axial cam driven in rotation by the output shaft, and a push rod linearly driven by the axial cam. A cartridge is removably attachable to the handpiece housing and includes a cartridge housing, a needle assembly, a piston in the housing engaging the needle assembly and linearly driven forward by the push rod, and a first biasing member urging the piston rearward.

The device includes an outer conductor and an inner conductor arranged approximately coaxial with each other. The outer conductor surrounds the inner conductor. The outer conductor and the inner conductor are arranged and configured to generate an electromagnetic field with lines of force extending from a front surface of the inner conductor to a front surface of the outer conductor. The device further includes an energy delivery window arranged in front of the outer conductor and the inner conductor.

An integrated system for increasing skin rejuvenation of a region of a patient's skin and treating subcutaneous fat associated with the region is provided. The system includes at least one first applicator having one or more RF electrodes adapted to be placed on the region of the patient's skin without penetrating the skin. At least one of said RF electrodes is configured to apply RF energy to the region of the patient's skin to heat up to a temperature in a specified temperature range. The system also includes at least one second applicator, in communication with an optical system. The optical system includes at least one laser source and is adapted to provide homogeneous illumination to the skin surface to effect at least one target tissue at a given depth range and power density range.

The cannula can have a connector configured to be electrically connected to a source of electrical power; a tip comprising: a printed circuit board (PCB); a first LED operatively connected and attached to the PCB and configured to emit light in a first wavelength range; and a shell configured to allow the light in the first wavelength range to pass from the first LED outside of the shell; and a middle section located between the connector and the tip, the middle section comprising: a hollow tube attached to the shell, the tube having apertures for collecting a liquid fat into the tube.

Systems, instruments, and methods for minimally invasive procedures including one or more of fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision are described. Embodiments include instrumentation comprising a scalpet assembly coupled to a carrier, and the scalpet assembly includes a scalpet array. The scalpet array includes one or more scalpets configured for fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision. The system includes a vacuum component coupled to the scalpet assembly and configured to evacuate tissue from the a site. The carrier is configured to control application of a rotational force and/or a vacuum force to the scalpet assembly.

Devices and methods for tissue treatment produce a mechanical stimulation therapy and electromagnetic field therapy. The mechanical stimulation therapy provides stimulation of blood circulation and stimulates treated cells. The electromagnetic field enables thermal treatment of tissue. Combination of both therapies improves soft tissue treatment, mainly connective tissue in the skin area and fat reduction.

Provided herein is a multifunctional aesthetic system including a housing, an electromagnetic array situated in the housing and having a plurality of electromagnetic radiation (EMR) sources, each EMR source configured to generate an EMR beam having a wavelength different than that of an EMR beam generated by another of the EMR sources, a controller in electronic communication with the array to operate two or more of the EMR sources to direct the EMR beam to a treatment area, and a sensor in electronic communication with the controller for providing feedback to the controller based on defined parameters to allow the controller to adjust at least one operating condition of the multifunctional system in response to the feedback.

The present disclosure is directed to devices, systems, and methods for sensing and discerning whether a distal portion of a fat grafting cannula or probe is disposed in fat tissue or muscle tissue during fat grafting procedures. In one aspect of the present disclosure, a fat grafting cannula or probe is provided including first and second electrodes. Each electrode is coupled to a circuit, e.g., disposed in an electrosurgical generator. During a fat grafting procedure, the electrodes contact patient tissue. Based on signals received from each electrode, the circuit is configured to determine whether a distal portion of the fat grafting cannula is disposed in a fat tissue or muscle tissue. If the circuit determines that the fat grafting cannula is disposed in muscle tissue, the surgeon operating the fat grafting cannula is alerted to ensure that processed fat is not injected into the muscle tissue of the patient.
