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: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices, systems and methods for air/water and flushing valves. For example, an endoscopic valve of the present disclosure may include a valve stem with contiguous first and second channels and with first and second ports formed within a sidewall of the valve stem. A series of seals may be disposed around an outer surface of the valve stem proximal and distal to the first and second ports. A gating member may be slidably disposed within the proximal channel and a valve insert may be disposed between the proximal and distal channels.

Abstract: This disclosure relates generally to a container and tube set and methods for fluid delivery, and particularly an integrated container and tube set suitable for use with an endoscope to supply liquids and/or gases to the endoscope. The integrated container and tubes may include a container (e.g., water reservoir) containing a fluid and a gas, and a plurality of tubes integrally formed with the container. The integrated container may include an irrigation supply tube having a first lumen in fluid communication with the fluid, a lens wash supply tube having a second lumen in fluid communication with the fluid, a gas supply tube having a third lumen in operative communication with the gas, and an optional alternative gas supply tube having a fourth lumen in fluid communication with the gas. The lens wash supply tube and the gas supply tube may be formed as a single, multi-lumen tube.

Abstract: A medical cleaning valve (or cleaning valve) may be configured to provide cleaning functionality to fluid (e.g., air and water) channels of an endoscope. Many embodiments described herein may include a cleaning valve (or valve) that is appropriate for single-use and therefore may be disposable. Accordingly, the valve may be made from a limited number of parts and materials, e.g., to limit its cost and/or manufacturing complexity. For example, multiple seals may be integrally formed with a valve stem. In another example, the valve may have an interface member, which may combine and simplify the functionality of a number of components, such as by connecting the valve stem to a valve well, sealing an opening to a lumen in the valve stem, and/or biasing the valve stem into a position relative to the valve well.

Abstract: Methods and systems for supplying gas and water to an endoscope system. An illustrative container and tube set may comprise a container configured to contain a fluid and having a bottom portion and a top portion, a lens water supply tube including a first end, a second end, and a first lumen extending therethrough, a gas supply tube including a first end, a second end, and a second lumen extending therethrough, a port positioned adjacent to the top portion of the container, and a flexible tube including a first end coupled to the top portion of the container, a second end, and a third lumen extending therethrough. The third lumen of the flexible tube may be configured to be in selective fluid communication with the interior of the container.

Abstract: Devices, systems, and methods for connecting tubes to an endoscope. A connector for connecting tubing, such as gas/lens wash tubing, to fluid ports of an endoscope may include a first end that couples with the tubing and a second end for engaging fluid ports of an endoscope. The connector may have a stabilizing component configured to facilitate securing the second end to the endoscope. In some cases, the connector may include a device coupling member configured to couple to the endoscope and a core structure adding stability to the device coupling member and configured to couple to the tubing. In some cases, the stabilizing component may include an actuator and a retention component that adjusts in response to actuation of the actuator.

Abstract: A biopsy needle system includes a needle extending from a tissue piercing distal end to a proximal end. The needle defines a lumen extending from the distal end at least a portion of a length thereof and houses a target tissue. The system also includes an elongated member defining a channel therethrough open at a proximal end. The channel is sized and shaped to permit passage of the needle therethrough. Further, the system includes an end cap coupled to the distal end of the elongate member. The end cap includes a hole extending through a lateral wall thereof. The hole is sized and shaped to permit passage of the needle therethrough. The end cap further includes a ramp extending from the channel to the hole to guide the needle through the hole. The ramp is angled with respect to a longitudinal axis of the elongated member.

Abstract: Medical devices, assemblies and methods for guarding sharp tips of medical needles are disclosed herein. Some embodiments include an expandable device configured to be at least partially disposed within the needle lumen. The device may include an expandable distal portion that is designed to shift between a first configuration in which the expandable distal portion has an outer diameter that is the same as or less than the inner diameter of the needle lumen and a second configuration in which the expandable distal portion has an outer diameter that is greater than the inner diameter of the needle lumen. An elongated inner member may be used to shift the expandable distal portion from the first configuration to the second configuration.
