Latest Patents

One of her latest patents is titled "Impedance Mediated Control of Power Delivery for Electrosurgery." This invention describes a method of controlling electrosurgical power delivery by comparing sensed tissue impedance to various impedance threshold values. Energy is delivered to tissue in a sealing cycle as a series of pulses. Each pulse has a profile with a preset energy starting value that increases at a ramping rate to a preset end value. Throughout each pulse, sensed impedance data are monitored and compared to impedance threshold values for RF setpoint, cumulative time, and energy cutback. If a high impedance event occurs, indicating low tissue presence, energy may be reduced. The sealing cycle is halted when the cumulative time with an impedance value exceeding the threshold reaches a specified limit.
