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) 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: 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 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: A locator device and system with an expandable element facilitating imaging of the locator device at a target site at a first anatomical location within a patient from a remote second anatomical location within the patient. The locator device may be formed of a material capable of being imaged from the remote second anatomical location. The locator device may be expandable to contact the interior of the anatomical structure at the first anatomical location to facilitate deployment and to resist movement with respect thereto. The locator device may be separable from the delivery system used to deliver the locator device and left in place at the target site. The locator device may expand the anatomical structure at the first anatomical location to facilitate imaging of such structure from the remote second anatomical structure. In some instances, the locator device may be returned to the delivery configuration and removed from the target site.

Abstract: An apposition device having a first elongate element movably coupled with a second elongate element. The second elongate element is deployable distal to the structures to be apposed, in a position transverse to the first elongate element. The first elongate element may be pulled to pull the second elongate element to move the structures into apposition. A third element may be positioned proximal to the structures to hold the structures in apposition. The third element may be a ratcheting element fixable in place with respect to the first elongate element. The apposition device may be deployed with a fine gauge needle. The second elongate element may be deployed from a side port in the needle facilitating deployment, and/or movement of the second elongate element with respect to the first elongate element and into a deployment configuration. Such arrangement may allow control of the first elongate element independent of the needle.

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: 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 an elongate body having a cavity at a distal end and a tissue retractor extendable distally from the distal end of the elongate body. The tissue retractor may include an expansion mechanism. The expansion mechanism may include a plurality of arms each having a first end coupled around a distal cap and expandable radially outward from the distal cap such that an anchoring mechanism on a second end of the arms is engageable with selected tissue for resection of the body lumen. The tissue resection device may further include a tissue resecting device.
