A system and method for providing treatment feedback for a thermal treatment device (100) is provided. In certain embodiments, a thermal transmitter (120) is configured to apply an amount of thermal energy (104) to a target site (106), the thermal energy having a selected frequency and a selected power level for penetration to a depth beneath the surface of the skin. A thermal imager (140) is also provided, the thermal imager (140) being configured to capture thermal data and thermal images of the target site. The device may further provide a thermal display (160) configured to display the thermal images and thermal data, providing feedback to a user (201).

Systems for treating a subject's tissue can include a thermally conductive cup with vacuum features configured to facilitate removal of air located between the cup and the subject's skin. The vacuum features can extend along cup to provide airflow paths to a vacuum port. The applicator can cool and/or heat the retained tissue to affect targeted tissue. After the treat period, the vacuum can be reduced or stop and the applicator can be removed from the subject.

The present invention provides methods and devices for controlling a cold slurry that is delivered to a target tissue and for limiting heat transferring from surrounding tissue to the target tissue. In particular, a balloon structure is deployed at or near a point of delivery to act as a physical and/or thermal barrier. In some instances, the balloon structure can act as a pressure device obstructing the flow of warm blood into a treatment area, which can melt the cold slurry.

In methods for treating a patient, a time varying magnetic field is applied to a patient's body and causes a muscle contraction. The time-varying magnetic field may be monophasic, biphasic, polyphasic and/or static. The method may reduce adipose tissue, improve metabolism, blood and/or lymph circulation. The method may use combinations of treatments to enhance the visual appearance of the patient.

Treatment systems include conformable applicators and adhesive liners for performing cryotherapy. Aspects of the technology are further directed to treatment methods and conformable applicators capable of affecting target regions. The conformable applicators and liners can be applied to a wide range of treatment sites. The liner can include a thermal coupling substance within a sealed reservoir to promote thermal coupling with the target region. A strap assembly can hold the applicator against the treatment site, and a holder assembly can be adhered to the subject's skin to inhibit, limit, or substantially prevent movement of the applicator along the subject's skin.

Described are methods for inducing browning of adipose tissue. More specifically, the present disclosure relates generally to methods for inducing browning of adipose tissue remote to the treatment location. The methods can include at least a first treatment and a second treatment, wherein the treatments comprise applying a cooling element to a local adipose tissue deposit, wherein the cooling element cools the local adipose tissue deposit to a temperature of between 0 C. to 30 C. for a period of time sufficient to induce browning of adipose tissue in one or more areas of the subject's body remote to the local adipose tissue deposit.

A treatment system for cooling subcutaneous lipid-rich cells in a human subject includes an applicator and a control unit. The treatment system has a cooling mode for cooling tissue and a heating mode for warming tissue. The control unit includes a circulation circuit in fluid communication with the applicator, a chiller apparatus configured to chill fluid from the applicator circulation circuit, and a heater apparatus to warmed fluid from the applicator circulation circuit. The control unit mixes the chilled fluid and/or the warmed with fluid in the applicator circulation circuit control the temperature of the fluid circulated in the applicator.

Devices, systems and methods for removing heat from subcutaneously disposed lipid-rich cells are disclosed. In selected embodiments, suction and/or heat removal sources are coupled to an applicator. The applicator includes a flexible portion and a rigid portion. The rigid portion includes a thermally conductive plate and a frame coupling the thermally conductive plate and the flexible portion. An interior cavity of the applicator is in fluid communication with the suction source, and the frame maintains contiguous engagement between the heat removal source and the thermally conductive plate.

A treatment device for removing heat from subcutaneous lipid-rich cells of a subject having an actuator that provides mechanical energy to the tissue. The mechanical energy provided may include a vibratory component that can range between low and ultra-high frequencies, and such energy may include various combinations of two or more frequencies tailored to produce the desired effect on the subcutaneous tissue. Disruption of adipose tissue cooled by an external treatment device may be enhanced by applying mechanical energy to cooled tissue. Furthermore, such mechanical energy may impart a vibratory effect, a massage effect, a pulsatile effect, or combinations thereof on the tissue.

Embodiments are directed to systems and methods for combined magnetic and optical treatments, for example by combined applications of optical waves and magnetic fields. An optical waves generating device may be used to provide optical waves for optical treatment. Magnetic field generating devices may be used to provides time-varying magnetic fields for magnetic treatment.
