The elongated shaft defines a channel along the longitudinal axis between the proximal and distal portions. The first feeder is disposed in distal portion of the elongated shaft and extends along and is rotatable about a first rotation axis. The second feeder is disposed in the distal portion of the elongated shaft, and extends along and is rotatable about a second rotation axis that is parallel to and offset from the first rotation axis. The first and second feeders are configured to cooperate to draw tissue disposed between the first and second feeders proximally into the channel.Type: ApplicationFiled: August 28, 2018Publication date: March 21, 2019Inventors: SCOTT J. PRIOR, NIKOLAI D. BEGG

Publication number: 20190083124Abstract: Systems (10) and methods (12) of controlling an ultrasonic surgical tool (20) with a console (22) are provided. A first drive signal (40) is applied to the ultrasonic surgical tool (20). A characteristic of a harmonic signal (44) resulting from application of the first drive signal (40) to the ultrasonic surgical tool (20) is acquired. A cancellation signal (70) is generated based on the characteristic of the harmonic signal (44). The first drive signal (40) and the cancellation signal (70) are combined to produce a second drive signal (80) that is sinusoidal. The second drive signal (80) is applied to the ultrasonic surgical tool (20) such that presence of the harmonic signal (44) resulting from application of the second drive signal (80) is reduced relative to presence of the harmonic signal (44) resulting from application of the first drive signal (40).Type: ApplicationFiled: July 14, 2016Publication date: March 21, 2019Applicants: Stryker Corporation, Stryker CorporationInventor: Adam Darwin Downey

Publication number: 20190083125Abstract: Various devices related to a therapeutic ultrasound device for use during a medical procedure to cauterize tissue are disclosed. The device includes an apparatus for tissue engagement. The apparatus includes a first jaw and a second jaw that each includes a body portion and an ear located adjacent to the body portion. The body portion is configured to receive an acoustic stack and the ear includes a slot configured to receive a first pin. The first and second jaws include an opening located between the body portion and the ear. The opening is configured to receive a second pin such that the first jaw and the second jaw are configured to rotate about the second pin.Type: ApplicationFiled: October 18, 2017Publication date: March 21, 2019Inventors: Stuart B. Mitchell, Eric Hadford, Daniel Baker

Publication number: 20190083126Abstract: Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating one or more abrasive elements within the vessel. The abrasive elements can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly that includes a driver for rotating the drive shaft. In particular implementations, individual abrasive elements are attached to the drive shaft at differing radial angles in comparison to each other (e.g., configured in a helical array). The centers of mass of the abrasive elements can define a path that fully or partially spirals around the drive shaft. In some embodiments, a distal stability element with a center of mass aligned with the longitudinal axis is fixedly mounted to the drive shaft.Type: ApplicationFiled: November 15, 2018Publication date: March 21, 2019Inventors: Albert Selden Benjamin, Cassandra Ann Piippo Svendsen, Charles Anthony Plowe, Paul Joseph Robinson

Publication number: 20190083127Abstract: Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating an abrasive element within the vessel. The abrasive element can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly. In particular embodiments, the handle assembly includes a compressed gas driven turbine member that drives rotation of the drive shaft. The turbine member can be rotatably attached to a carriage that is longitudinally translatable in relation to a housing of the handle assembly. The handle assembly can include a latch mechanism that when actuated allows the carriage to translate to a proximal-most position. While the carriage is in the proximal-most position, an open pathway is created so that a guidewire can be slidably passed through the handle assembly and a lumen of the drive shaft.Type: ApplicationFiled: November 20, 2018Publication date: March 21, 2019Inventors: Cassandra Ann Piippo Svendsen, Charles Anthony Plowe, Albert Selden Benjamin, Paul Joseph Robinson, Evan Leingang

Publication number: 20190083129Abstract: Surgical devices and methods of using the surgical devices are disclosed. The surgical devices generally include a trocar, a cannula releasably mounted on the trocar, and a propulsion system operatively connected to the trocar. The cannula includes a hub, and has a central opening through which the trocar extends. The propulsion system is operable to drive the trocar axially in a forward direction away from a proximal end of the surgical device.Type: ApplicationFiled: February 17, 2017Publication date: March 21, 2019Inventors: Matthew Paul LaConte, James C.

Publication number: 20190083130Abstract: A system includes an access cannula, a deployment cannula having a plurality of engagement arms, and a containment bag. The deployment cannula is slidable within the access cannula between an initial condition, wherein the engagement arms are retained in a contracted configuration, and a deployed condition, wherein the engagement arms are disposed in an expanded configuration. The containment bag includes an open end portion configured to receive the first elongated tubular member and the second elongated tubular member. In the initial condition, a portion of the containment bag towards the open end portion is positioned adjacent at least one of the first elongated tubular member or the second elongated tubular member. In the deployed condition, the portion of the containment bag is expanded such that the portion of the containment bag is spaced-apart from the at least one of the first elongated tubular member or the second elongated tubular member.Type: ApplicationFiled: August 22, 2018Publication date: March 21, 2019Inventors: SCOTT J.
