## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Application No. 61/329,449 filed Apr. 29, 2010, which is incorporated herein by reference in its entirety as if fully set forth herein.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to a facial muscle toner system. More specifically, the present invention relates to a facial muscle toner system that is portable and has interchangeable therapy distribution instruments.
2. Background Information
Electrical micro-current stimulation has proven to be an effective method of improving facial skin tone. The method is effective enough that a flourishing industry provides medical treatments and devices which apply micro-current to sub-dermal muscles of a human face to improve facial skin appearance. In general, such devices work by causing a contraction of the facial muscles to re-educate the muscles.
There are around a dozen groups of facial muscles, with a total number of facial muscles, depending on the method of counting, that may range as high as roughly one hundred. These muscles are crucial to human identity and self-expression, as the face is the primary non-verbal communication device used by human beings.
Previous attempts at stimulation to improve facial skin tone have included an apparatus with a large cumbersome control body that houses control components. The large control body is connected to two electrodes applied to a face. The control body and electrodes are not easy for transporting to other locations. Furthermore, the electrodes are permanently attached to the control body and do not offer the operator multiple options for stimulation therapy.
In view of the above, it will be apparent to those skilled in the art from this disclosure that there exists a need for an improved facial muscle toner system that is portable and has interchangeable therapy distribution instruments. This invention addresses this need in the art as well as other needs, which will become apparent to those skilled in the art from this disclosure.

The receptacle portion 64 includes a first actuator 102 and a second actuator 104, both of which are disposed on opposing sides of the receptacle portion 64. The first and second actuators 102, 104 slide longitudinally along the exterior surface of the receptacle portion 64. The therapy distribution instrument 66 includes a first rigid member 106 and a second rigid member 108. The first rigid member 106 is connected to the first actuator 102 and the second rigid member 108 is connected to the second actuator 104. It will be apparent to one of ordinary skill in the art from this disclosure that the first and second actuators 102, 104 can be actuated by an electric motor, for example, and can be disposed within the hand piece unit 4. The first and second rigid members 106, 108 extend upwardly from the receptacle portion 64. The first rigid member 106 has a substantially straight lower portion and a curvature at an upper portion that curves across the width of the receptacle portion 64 and towards the second rigid member 108. The second rigid member 108 extends coaxially with axis A and is substantially straight. The first rigid member 106 also has a first contact section 110 disposed at an end portion of the first rigid member 106. The second rigid member 108 includes a second contact section 112 disposed at an end portion of the second rigid member 108. The first and second contact sections 110, 112 are comprised of an exposed conductive material, such as copper, to deliver the micro-current therapy to the face. Conductors (not shown) run through the first and second rigid members 106, 108 to conduct the micro-current to the first and second contact sections 110, 112. In one embodiment, the first contact section 110. Referring to FIG. 22, in operation, when the facial muscles are to be stretched, the first and second contact sections 110, 112 are adjacent each other and placed against the skin above a selected facial muscle. The first actuator 102 moves the first rigid member 106 and the first contact section 110 upwardly away from the second contact section 112 to form a treatment opening 114 so as to stretch out the facial muscle. The first and second actuators 102, 104 dictate the size of the treatment opening 114 by the direction of their movements. During the stretching and/or after, therapy is applied to the skin touching the first and second contact sections 110, 112 and the facial muscle underneath the area of skin. The therapy includes micro-current stimulation delivered through the skin to the facial muscle.
In another operation of the portable hand piece unit 4 of the present embodiment, the skin and facial muscles can be pinched or shortened. Specifically, the therapy distribution instrument 66 is placed on the skin over the selected facial muscle with the treatment opening 114 of sufficient magnitude to grasp the skin and facial muscle between the first and second contact sections 110, 112. The first and second actuators 102, 104 then cause the first and second contact sections 110, 112 to pinch the skin and/or facial muscle while a micro-current stimulation is delivered.
In one embodiment, one or both of the first and second contact sections 110, 112 includes a roller 116. The roller 116 is rotatably disposed at the contact section 110, 112 and advantageously provides a rolling force on the muscle in a massaging action. The roller 116 is further advantageous when a rocking motion is desired during the micro-current stimulation.
