The ultrasound assembly can be connected to the distal end of the shaft. The ultrasound assembly can include a casing, at least one ultrasound transducer disposed within the casing, and a second lumen that extends through the ultrasound assembly and is in fluid communication with the first lumen. The at least one ultrasound transducer can be configured to generate acoustical waves having an intensity and frequency sufficient to disrupt, but not substantially damage, the biological tissue so that the biological tissue can be aspirated through the device.

  • Patent number: 10117667
    Abstract: In one general aspect, various embodiments are directed to systems and methods for controlling a surgical instrument. The surgical instrument may comprise an ultrasonic transducer, a blade extending distally from the ultrasonic transducer along a longitudinal axis, and a motor coupled to the ultrasonic transducer. The motor, when activated, may rotate the ultrasonic transducer and the blade about the longitudinal axis. A control system may receive an indication to operate the surgical instrument according to an ultrasonic-only mode. The control system may instruct the motor to rotate the blade to a park position, and activate the ultrasonic transducer to longitudinally vibrate the blade.

  • Patent number: 10117706
    Abstract: An apparatus for operating on tissue includes an elongate shaft extending distally from a body and an end effector at a distal end of the elongate shaft. The end effector includes a first jaw that is selectively pivotable toward and away from a second jaw to capture tissue and a firing beam. The firing beam is configured to advance relative to the first and second jaws to sever captured tissue and retract relative to the first and second jaws after the captured tissue has been severed. The apparatus further includes a debris removal element in communication with the firing beam. The debris removal element is configured to engage at least a portion of the firing beam at least during retraction of the firing beam relative to the first and second jaws to thereby remove at least some debris from the firing beam.

  • Patent number: 10099045
    Abstract: Antibiotics are administered in a surgical site subcutaneously via a small or stab incision in the surgical field. Transcutaneous ultrasonic vibrations are applied across the surgical field, which is then opened in the usual manner, to thereby provide a surgical field which contains a vastly higher and more effective level of antibiotic. At the same time the underlying tissue is hydrated.

  • Patent number: 10098656
    Abstract: Embodiments of the present invention provide improved methods and apparatus of treating the prostate. In many embodiments, at least a portion of the prostate is enucleated with a water jet, in order to decrease the invasiveness of the surgery. The access to the prostate can be provided with one or more of open surgical access, percutaneous access, or urethral access. The prostate can be enucleated such that an inner portion of the prostate comprising adenomatous tissue of the prostate is separated from a portion an outer the prostate comprising the capsule. In many embodiments, the patient is treated with energy of the water jet configured to separate the capsule from the inner tissue of the prostate and to inhibit cutting of blood vessels.

  • Patent number: 10092313
    Abstract: A tubular structure comprising multiple overlapping layers surrounding a lumen has flexibility and structural integrity by allowing portions of the layers to slip relative to each other. One embodiment includes a support layer having a wired coil, braid or weave support element underlies at least one overlying layer. The support layer is fixed to the overlying layer at a bonding point and the remaining portion of the support layer is not fixed to the overlying layer, i.e. “free portion”. The support layer is permitted to slip at the free portion of the support layer, relative to the overlying layer. Further flexibility may be provided by a coil element of the support layer having substantial gaps between the loops of the coil to impart high flexibility of the tubular structure.

  • Patent number: 10086217
    Abstract: An ultrasonic motion generator includes a non-resonant inverter, an ultrasonic transducer, and a comparator. The non-resonant inverter inverts direct current (DC) to alternating current (AC) having a first frequency. The ultrasonic transducer is electrically coupled with the non-resonant inverter and generates an ultrasonic motion based on the inverted AC. The comparator automatically detects a deviation of the first frequency from a resonant frequency of the ultrasonic transducer based on motion current passing through the ultrasonic transducer and generates an output signal based on the deviation to drive the non-resonant inverter.
