8.2 Renuvion®—360° tissue treatment

It is known that electrical energy takes the path of least resistance. RF energy flows through the conductive plasma beam generated by the Renuvion® system. This conductive plasma beam can be thought of as a flexible wire or electrode that "connects" to the tissue that represents the path of least resistance for the flow of the RF energy. This tissue is typically either that which is in the closest proximity to the tip of the Renuvion® device or the tissue that has the lowest impedance (is the easiest to pass energy through). When used for the coagulation of subcutaneous soft tissue, this means that the energy from the Renuvion® device is not directed or focused in any set direction when activated in the subdermal plane. As the tip of the Renuvion® device is drawn through the subdermal plane, new structures are introduced to the tip of the device, and the path of least resistance is constantly changing. As the energy is constantly finding a new preferred path, the plasma beam quickly alternates direction, seeking out new structures to heat (see Figure 7). This allows for 360° tissue treatment without the need for the user to redirect the flow of energy. Since the collagen framework of the FSN is typically the closest tissue to the tip of the Renuvion® device, the vast majority of the energy delivered by the device results in coagulation and contraction of the fibroseptal bands. Maximizing the energy flow to the FSN expedites the soft tissue contraction process.
