Abstract
A device for providing elliptical path motion to skin or other surface. The device includes a motor, shaft, and a cam having at least one offset axis cam lobe for creating offset motion. A mounting bracket assembly that has a pair of arms associated with the motor can be moved by the cam in an elliptical path having X-axis, Y-axis and, in exemplary embodiments, Z-axis movement. The mounting bracket assembly may have two brackets, each being associated with an oscillating plate. Each oscillating plate may have a plurality of protrusions or tufts of bristles protruding therefrom. Elliptical movement of the oscillating plates creates offset elliptical motion of the protrusions associated with each oscillating plate. A fluid delivery system may be incorporated to provide fluid through the device. The device may be used for cleaning, stimulation or treatment of skin.
