Patent number: 11969201Abstract: A controller for an electrosurgical generator includes an RF inverter, a signal processor, a software compensator, a hardware compensator, and an RF inverter controller. The RF inverter generates an electrosurgical waveform and the signal processor outputs a measured value of at least one of a voltage, a current, or power of the electrosurgical waveform. The software compensator generates a desired value for at least one of the voltage, the current, or the power of the electrosurgical waveform, and the hardware compensator generates a phase shift based on the measured value and the desired value. The RF inverter controller generates a pulse-width modulation (PWM) signal based on the phase shift to control the RF inverter.Type: GrantFiled: August 17, 2021Date of Patent: April 30, 2024Assignee: Covidien LPInventors: Robert H. Wham, Edward L. Brannan, William D. Faulkner, Mark A. Johnston, Aaron G. Mattmiller, Donald L. Tonn

Patent number: 7673846Abstract: A pressure regulating valve includes a body having an outer surface, the interior of the body defining an inlet chamber adapted to receive a fluid at a process pressure, and an outlet chamber. The body includes at least one inlet passage communicating with the inlet chamber and the outer surface, and at least one outlet passage communicating with the outer surface and the outlet chamber. A reference housing is adapted to be disposed in fluid communication with a fluid at a predetermined reference pressure. An annular membrane is disposed between the body and the reference housing, so as to circumscribe the inlet and outlet passages. The membrane is arranged such that, when the reference pressure is higher than the process pressure the membrane engages at least one outlet passage, and when the process pressure is higher than the reference pressure, the membrane is not engaged with the outlet passage.Type: GrantFiled: December 18, 2006Date of Patent: March 9, 2010Inventors: Jeffrey D. Jennings, Franz W. Kellar, Donald G. Faulkner

Patent number: 7661935Abstract: An ultrahigh pressure pump includes a frame including at least one radially-extending member having an outer frame pivot disposed at outer end thereof; a crank rotatably mounted in the frame and adapted to be driven by a power source and a crank pin offset from a rotational axis of the crank; and at least one radially-extending telescoping pump subassembly having inner and outer ends. The outer end of each pump subassembly is attached to the outer frame pivot for pivotal swinging movement thereabout, and the inner end is pivotally attached to the crank pin.

Publication number: 20090087328Abstract: A pulse generator has a rigid body with a resilient flow conduit passing therethrough. Pressure is periodically selectively applied to the interior of the body which compresses the flow conduit and induces a pressure pulse in the fluid contained therein.
