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.

Systems and methods for treating a body region are provided herein. A treatment device for treating a body region is provided, and may include a first applicator and a second applicator. The first and second applicators are held on the body region by a belt. The first applicator may include a first magnetic field generating device and a radiofrequency electrode. The second applicator may include a second magnetic field generating device. The first and second magnetic field generating devices may each generate a time-vary magnetic field with a plurality of sequential magnetic impulses to cause muscle contraction in the body region. The radiofrequency electrode may provide radiofrequency waves causing heating of tissue within the body region. The treatment device may further include an energy storage device and a switching device. The switching device my discharge energy from the energy storage device to the first or the second magnetic field generating device to generate the time-vary magnetic field.

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.

Combined methods for treating a patient using time-varying magnetic field are described. The treatment methods combine various approaches for aesthetic treatment. The methods are focused on enhancing a visual appearance of the patient.

A method of treating tissue of a patient uses a device including a mother case, a belt, at least one treatment unit and at least two applicators. The treatment method may include attaching first and second applicators to the belt at a working distance to the patient's surface, and providing different treatment energy to the first applicator and the second applicator. A treatment pattern is created by the applicators providing the different treatment energies. The hardware pattern or positions of the applicators on the belt may be changed before and/or during the treatment. The hardware pattern may be based on selected treatment effect and body part.

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.

Systems for treating a subject's tissue can include a thermally conductive cup, a sealing member, and/or a liner assembly. The systems can include an applicator capable of being reconfigured for a particular treatment site. Components of the applicator can be replaced to achieve a desired configuration. The replaceable components can include contoured heads, liners, and/or sensors. The applicator can draw a vacuum to install various components and/or draw tissue into the applicator. The applicator can cool and/or heat the tissue to affect targeted tissue.

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.

A system for treating a subject can include an adjustable vacuum applicator configured to receive the subject's tissue by applying a vacuum. The vacuum applicator can have an cavity adjustment mechanism with different modes for widening and narrowing a tissue-receiving cavity to adjust the thermal contact between the vacuum applicator and the subject's tissue within the applicator. Sidewalls of the vacuum applicator can be moved to positive draft angle positions to help draw tissue deeper into the tissue-receiving cavity.

Application systems, disposable interface assemblies and methods for cooling subcutaneous lipid-rich tissue. One embodiment of an application system includes a cooling unit, a cryoprotectant vessel, a contact member and an array of selectively addressable heating elements. The cryoprotectant vessel is configured to contain a fluidic cryoprotectant such that at least a portion of the cryoprotectant is cooled by the cooling unit to a desired base temperature. The contact member is attached to the cryoprotectant vessel and includes a backside in contact with the cryoprotectant and a front side opposite the backside. The contact member is configured to allow the cryoprotectant to flow from the backside to the front side. The array of selectively addressable heating elements is carried by the contact member.
