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 and water 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. In one or more embodiments, manufacture of the valve sets and/or valve interface mechanisms, collectively referred to as flow controllers, may be simplified, such as to make it economical to dispose of the flow controller after a single use.

Abstract: A stent system may include a stent including a first leg having a first end fixedly attached to the distal end of a main body portion and extending distally from the distal end of the main body portion in a deployed configuration, and a second leg having a first end fixedly attached to the distal end of the main body portion and extending distally from the distal end of the main body portion in the deployed configuration. The second leg may extend proximally from the distal end of the main body portion in a delivery configuration. A stent system may include a bifurcated delivery sheath and two guidewires for delivery of two stents at the same time. A method of treating a body lumen may include delivering a contrast fluid including an anti-gas agent while implanting a stent in the body lumen.

Abstract: The present disclosure relates to the field of tissue dissection. Specifically, the present disclosure relates to medical devices that lift and retract tissue during a dissection procedure to improve visualization of the target tissue and mitigate obstructions for dissection tools. In particular, the present disclosure relates to devices that transition from a constrained to an unconstrained bowed configuration to immobilize and retract the dissected portion of target tissue during a dissection procedure.

Abstract: The present disclosure relates generally to the field of medical devices and establishing fluid communication between body lumens. In particular, the present disclosure relates to devices and methods for placing the muscularis layers of first and second body lumens in contact to establish a long term or permanent open flow or access passage therebetween.

Abstract: The present disclosure relates generally to the field of medical devices and establishing access to body passageways. In particular, the present disclosure relates to devices, systems and methods to facilitate entry of an endoscopic accessory tool into and/or through patient-specific anatomies. For example, the devices, systems and methods of the present disclosure may transmit mechanical motion to the distal end of an endoscopic accessory tool to facilitate atraumatic access to tortuous or otherwise restricted anatomies.

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.

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: Various embodiments are generally directed to fluid container adapters that couple with a fluid container, so to enable access to the contents of the fluid container, such as from an endoscopic system via a tubing set. Several embodiments are particularly directed to a fluid container adapter that can couple with an opening in a variety of fluid containers to place one or more tubes in fluid communication with an interior of any particular one of the variety of fluid containers.

Abstract: Various embodiments are generally directed to fluid container enclosure systems that couple with a fluid container and enable different systems, such as endoscopic systems, to access the contents of the fluid container, such as via a tubing set. The enclosure systems are configured to fit a wide range of fluid container necks, ports, or other openings, including various opening dimensions and thread finishes. In one embodiment, an enclosure system may include a plug having a sleeve extending therefrom. The plug may be deformed manually or via a plunger system to reduce the outer dimension thereof to fit the plug in the neck of a fluid container. Once the plug is arranged within the neck, the sleeve may be folded down over an outer surface of the neck to form or reinforce a seal between the enclosure system and the neck of the fluid container. Other embodiments are described.
