Abstract: A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, and an end effector. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The end effector comprises an ultrasonic blade in acoustic communication with the ultrasonic transducer. The ultrasonic blade includes a recess region having a plurality of recesses. The recess region is tapered such that the cross-sectional area of the recess region decreases along the length of the recess region. The ultrasonic blade is also curved such that a central longitudinal axis of the ultrasonic blade extends along a curved path. A reference circuit is used to account for voltage drops of unknown values during operation of the surgical apparatus.

Abstract: Exemplary embodiments of the present disclosure relate to devices, systems, and methods for tissue resection in a body lumen of a patient, and may include a body extending along an axis and a distal cap positioned distally of the body and coupled to a shaft extending along the axis. The body and the distal cap may be movable relative to each other. An anchoring mechanism may be capable of engaging the body and the distal cap proximate a selected tissue for resection in the body lumen. A tissue capture device may be deployable from the tissue resection device such that a selected tissue for resection is securable by the tissue capture device. The tissue resection device may further include a tissue resecting device for resecting the selected tissue for resection.

Abstract: Apparatuses for cleaning an endoscope as well as methods for making and using the same are disclosed. An example apparatus may include a control unit. A shaft may be configured to be coupled to the control unit. The shaft may have a distal end region. A cleaning member may be coupled to/couplable to the distal end region of the shaft. The control unit may be configured to move the cleaning member.

Abstract: Various embodiments are generally directed to devices, systems, and methods for controlling the flow of fluids in endoscopic systems, such as endoscopic ultrasound (EUS) enabled endoscopes. Some embodiments are particularly directed to valve sets and/or valve interface mechanisms for controlling air, water, and/or suction flow through a valve well for an endoscopic system. Several embodiments are directed to user interface mechanisms and techniques for enabling an operator to interact with and control endoscope valves. Many embodiments are directed to mechanisms and techniques for translating interface input motion into valve control motions. In one or more embodiments, the valve sets and/or valve interface mechanisms may be disposable.

Abstract: A detachable motor-powered surgical instrument. The instrument may include a housing that includes at least one engagement member for removably attaching the housing to an actuator arrangement. A motor is supported within the housing for supplying actuation motions to various portions of a surgical end effector coupled to the housing. The housing may include a contact arrangement that is configured to permit power to be supplied to the motor only when the housing is operably attached to the actuator arrangement.

Abstract: The present disclosure relates generally to medical devices, ligators, and methods for deploying ligation bands around a portion of tissue. In some embodiments, a medical device may include a plunger biasable within a first tube, the first tube including a band along a first tube distal end. The medical device may further include a second tube surrounding the first tube, the second tube comprising a second tube proximal end opposite a second tube distal end, wherein the second tube distal end includes an engagement member operable to dispense the band from the first tube in response to axial movement of the first and second tubes relative to one another.

Abstract: A system for containing and transporting a medical device may include a container including a bottom face and surrounding side faces as a closed first end and an open second end to form an inner portion for receiving and retaining the medical device. The liner may be extendable over the side faces to line the inner portion of the container to an outer surface of the bottom face of the container. The liner may act as a protective barrier to the container to minimize contamination when receiving and/or retaining a used medical device. First and second covers may be removably attachable to the container, over the liner, to enclose a medical device therebetween. A first cover may have a color or marking indicating the medical device is “clean”, while a second cover may have a color or marking indicating the medical device is “used”.

Abstract: In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.

Abstract: A surgical stapling system is disclosed comprising a proximal housing portion, a distal housing portion removably coupleable to the proximal housing portion at a coupling interface, a motor, and a power source in electrical communication with the motor along an electrical communication pathway that does not traverse the coupling interface. The power source is configured to provide energy to the motor along the electrical communication pathway. The power source is permitted to provide energy to the motor based on the distal housing portion being coupled to the proximal housing portion.
