Patent attributes
Exemplary aspects of a treatment device are described, such as a body, a plurality of generator elements, and a housing. The body may contain a processing unit. The plurality of generator elements may be disposed within the body and be independently operable to output different energy types. The housing may be removably securable to the body. The housing may have a proximal end, a distal end, and a circumferential wall surrounding the plurality of generator elements when the housing is secured to the body, the distal end of the housing being positionable on skin about an area of the skin. The housing also may include an insulating material for permitting flows of the different energy types toward the area of skin and limiting flows of the different energy types outside the housing. Related apparatus, methods, and systems are described.
