  • Patent number: 10894084
    Abstract: In this study, we demonstrated a unique application of our Metal-Assisted and Microwave-Accelerated Decrystallization (MAMAD) technique for the de-crystallization of uric acid crystals, which causes gout in humans when monosodium urate crystals accumulate in the synovial fluid found in the joints of bones. Given the shortcomings of the existing treatments for gout, we investigated whether the MAMAD technique can offer an alternative solution to the treatment of gout. Our technique is based on the use of metal nanoparticles (i.e., gold colloids) with low microwave heating to accelerate the de-crystallization process. In this regard, we employed a two-step process; (i) crystallization of uric acid on glass slides, which act as a solid platform to mimic a bone, (ii) de-crystallization of uric acid crystals on glass slides with the addition of gold colloids and low power microwave heating, which act as “nano-bullets” when microwave heated in a solution.

An electrosurgical system configured to output therapeutic RF energy may refrain from outputting RF energy in order to measure an RF interference for a group of candidate frequencies, and to select a frequency from the group of candidate frequencies for which the measured RF interference is below a threshold value, and to produce a feedback signal (a control signal) at the selected frequency to control operation of the electrosurgical system. During operation of the electrosurgical system the feedback signal may be filtered by a BPF whose fundamental frequency is set to the selected frequency, to thus obtain an interference free feedback signal and, consequently, a reliable control of the electrosurgical system.

    Abstract: Systems and methods for designing RF pulses using a technique that directly controls temperature rise via a compression model that is based on virtual observation points (“VOPs”) are provided. Thermal pre-simulations are first carried out for a given RF exposure time, coil, and subject model in order to obtain complex temperature matrices, after which the compression scheme follows. As one example, the thermal model employed can be Pennes' bio-heat equation. Focusing design constraints on the temperature rise instead of the absolute temperature allows for uncertain parameters to be dropped from the thermal model, making it more robust and less prone to errors. In some embodiments, the algorithm used for RF pulse design is the active-set (“A-S”) method.

    Abstract: A surgical apparatus comprises a body, a shaft assembly, an end effector, and a blade cooling system. The shaft assembly couples the end effector and the body together. The shaft assembly comprises an acoustic waveguide and defines an interior space. The acoustic waveguide is configured to couple with an ultrasonic transducer. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with the ultrasonic transducer. The clamp arm is configured to pivot toward and away from the ultrasonic blade. The shaft assembly comprises an inner tube configured to longitudinally translate to thereby pivot the clamp arm toward and away from the ultrasonic blade. The cooling system is operable to deliver liquid coolant a distal portion of the shaft. A trigger of the body is operable to rotate to thereby translate the ultrasonic blade into and out of the interior space of the shaft assembly to thereby cool the ultrasonic blade.

  • Patent number: 10278774
    Abstract: In one embodiment, a device is provided including an expandable support member having a first portion and a second portion is provided. The first portion is adapted to have a smaller expansion index than the second portion. A therapeutic or diagnostic instrument is supported, at least in part, by the expandable support member first portion. In another embodiment, the support member is adapted for non-uniform expansion of the first and second portions. There are also described methods of forming therapeutic devices. There are also described methods of providing therapy to tissue in a body by positioning a device in proximity to tissue in a body selected to receive therapy. Next, the expandable support member second portion is expanded until the instrument is at a therapeutic position relative to the tissue in a body selected to receive therapy. Thereafter, therapy or diagnosis is provided to the selected tissue using the device.

  • Patent number: 10182865
    Abstract: Microwave catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present application, for example, is directed to apparatuses, systems, and methods that incorporate a catheter treatment device comprising an elongated shaft. The elongated shaft is sized and configured to deliver a microwave transmission element to a renal artery via an intravascular path. Renal neuromodulation may be achieved via dielectric heating in the presence of microwave irradiation that modulates neural fibers that contribute to renal function or alters vascular structures that feed or perfuse the neural fibers.
