A system is provided to treat sleep apnea, with a method of use. The system includes a handpiece which includes at least one penetrating electrode configured to penetrate tissue and one or more temperature sensors. A processor is coupled with the one or more temperature sensors and the at least one penetrating electrode, and a memory is configured to store instructions executable by the processor. The instructions, when executed, are operable to emit, by the at least one penetrating electrode, RF energy from the electrodes to heat a region of a base of a tongue until a target energy is delivered to the region. The instructions are also operable to measure, by the one or more temperature sensors, the temperature of the region.

An apparatus for removing a tattoo includes a control unit having one or more power sources; a head unit coupled to the control unit, wherein the head unit includes a body and a plurality of needles protruding from the body, wherein the plurality of needles includes at least one supply needle and at least one return needle; and a flexible tube coupling the head unit to the control unit, wherein the one or more power sources are electrically coupled to the plurality of needles through the flexible tube, wherein the control unit is configured to deliver power to the at least one supply needle such that power flows from the at least one supply needle to the at least one return needle during use.

A method for the removal of tattoos or skin discoloration includes applying a removal fluid to the skin using a pigmentation device or a knife, such that the removal fluid is applied by small-scale, partial removal of the epidermis. In addition, the disclosure involves a removal fluid for use in the method.

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.

Embodiments include a system comprising a cannula assembly configured for rotational fractional resection (RFR). The cannula assembly includes at least one cannula configured for rotational operation and enclosed in a depth guide configured to control an insertion depth of the at least one cannula. The depth guide includes a vacuum chamber configured to maintain vacuum to evacuate resected tissue generated by the RFR.
