    Abstract: A valve shaft for a valve assembly of a medical device. The valve shaft is shiftable between an off position in which the valve assembly is in an off configuration and does not fluidly communicate a fluid source with a patient, and an on position in which the valve assembly is in an on configuration fluidly communicating a fluid source with a patient. The valve shaft is formed of a valve shaft proximal component formed of a first material, and a valve shaft distal component formed of a second material. The first material is more rigid than the second material so that the valve shaft proximal component may have hard stop features limiting axial and/or rotational movement of the valve shaft. The second material is capable of forming a seal between the valve shaft distal component and another component of the valve assembly.

    Abstract: Suction valves for selectively fluidly coupling a suction pump with a working channel. An illustrative suction valve may comprise an elongate shaft having a longitudinal axis and extending from a first end to a second end, at least one aperture extending through a sidewall of the elongate shaft, a rigid base extending radially outward from an outer surface of the elongate shaft, and a compliant member extending between a first surface of the rigid base and the first end of the elongate shaft. In response to an applied force, the compliant member may be configured to compress to move the elongate shaft in a direction parallel to the longitudinal axis of the elongate shaft to a use configuration and in the absence of the applied force the compliant member may be configured to bias the elongate shaft to a rest configuration.

    Abstract: A device for treating hemorrhoids includes a first ligating member which moves between a first position in which the first member is tightened to a degree required to maintain a desired position of the first member around the first portion without significantly cutting off blood flow and a second configuration in which the first member is cinched down around the first portion to substantially cut off blood flow to the encircled first portion. Also, the device includes a first applicator having a proximal lumen and first and second opposed distal lumens open to the proximal lumen. The first member is extending from a proximal end distally through the proximal lumen into the first lumen to exit a distal end of the first lumen, loop around and enter the distal end of the second lumen. The first member is passing through the second lumen into the proximal lumen.

    Abstract: Methods and systems for providing a flow of fluid to an endoscope. An illustrative container and tube set arranged and configured to couple to an endoscope may comprise, a first container configured to contain a fluid, a first water supply tube including a first lumen extending therethrough and in selective fluid communication with the first container, a first gas supply tube including a second lumen extending therethrough and in fluid communication with the first container, a second container configured to contain a fluid, a second water supply tube including a third lumen extending therethrough and in fluid communication with the second container, and a fluid flow control mechanism positioned in-line with the second water supply tube, the fluid flow control mechanism configured to selectively fluidly couple the second container with the first container.

    Abstract: Methods and systems for refilling a container during an endoscopic procedure. An illustrative container may comprise a container extending from a first end to a second end and having a reduced diameter stem extending from the first end, the reduced diameter stem defining an opening for receiving a fluid, a water outlet, a gas inlet, and a port. The port may comprise a sealing ring defining an aperture extending from a first end to a second of the sealing ring, the aperture in fluid communication with the opening in the container, a cap positioned adjacent to the first end of the aperture of the sealing ring, and a biasing mechanism disposed between the container and the sealing ring.

    IPC: A61B1/00

    Abstract: An endoscope (e.g., a duodenoscope) includes a bifluidic valve for controlling the flow of water and air through a flexible tubular probe to respectively irrigate or insufflate an internal cavity of a patient. Some examples of the bifluidic valve include a flexible valve seal that allows air to flow in one direction but not in reverse. Different examples of the valve seal include various features, such as a set of overlapping flexible flaps arranged in a spiral, a rubber-like disc with an array of cross-slit perforations that open in response to a positive pressure differential across the disc, a resiliently expandable cone with multiple concentric ridges, a valve spool encircled by an elastic tubular piece that can expand radially to open an air passageway in the valve spool, and an elastic tube that in reaction to being compressed or otherwise shortened bulges radially outward to block an annular air passageway.

    Abstract: A valve assembly with a valve shaft shiftable within a valve well from an off position blocking fluid communication between ports in the valve well, and an on position allowing fluid communication between such ports. The on position may be proximal to the off position. The length of the valve shaft is selected simply to block access to one of the ports of the valve well when in the off position, and thus may be shorter than prior valve shafts. The valve shaft is along a distal end of an actuatable member of the valve assembly, and a user-engagement element may be provided along the proximal end of the actuatable member. The user-engagement element may be movable towards the valve shaft to move the valve shaft from the off position to the on position.
