Abstract: The present disclosure relates to devices, systems and methods for calculating the amount of energy delivered to tissue during an electrosurgical treatment. The present disclosure provides for a power supply that supplies electrosurgical energy to an applicator via a radio frequency (RF) output stage, a memory that stores at least one energy quantification function that determines an amount of energy delivered to patient tissue by the applicator and a controller that controls the power supply based on a selected power setting and determines the amount of energy delivered to the patient tissue based on the energy quantification function and the selected power setting. The controller counts the energy delivered to the patient tissue based on the selected power setting and a duration of activation time of the applicator at the selected power setting and displays the energy delivered in Joules.

Abstract: The present disclosure is directed to devices, systems, and methods for sensing and discerning whether a distal portion of a fat grafting cannula or probe is disposed in fat tissue or muscle tissue during fat grafting procedures. In one aspect of the present disclosure, a fat grafting cannula or probe is provided including first and second electrodes. Each electrode is coupled to a circuit, e.g., disposed in an electrosurgical generator. During a fat grafting procedure, the electrodes contact patient tissue. Based on signals received from each electrode, the circuit is configured to determine whether a distal portion of the fat grafting cannula is disposed in a fat tissue or muscle tissue. If the circuit determines that the fat grafting cannula is disposed in muscle tissue, the surgeon operating the fat grafting cannula is alerted to ensure that processed fat is not injected into the muscle tissue of the patient.

Abstract: An apparatus and method for cold plasma skin resurfacing is provided. In one aspect, a mask for use in fractionated skin resurfacing is provided. The mask includes a plurality of apertures distributed across a surface of the mask. The mask may be made of a flexible material including an adhesive surface, such that the mask may be applied to a contoured surface of a patient's skin while remaining fixed in place. The material is resistant to the effects of a cold plasma beam. In this way, a cold plasma beam applicator may be used to scan or apply a cold plasma beam over a surface of the mask, such that only the portions of a patient's skin exposed by the apertures of the mask are treated by the cold plasma beam.
