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: A device is for facilitating an over-the-scope application of a tissue treating element and includes an end cap and control members. The cap includes a proximal portion mounted over a distal end of a scope device and a distal portion including flaps. The proximal portion extends along a longitudinal axis from a proximal end to a distal end and includes a proximal channel extending therethrough. A proximal end of each flap is pivotally connected to the distal end of the proximal portion so that the flaps are movable between a closed configuration and an expanded configuration. A distal end of each of the members is connected to a corresponding flap so that a longitudinal movement of the members relative to the proximal portion of the cap moves the flaps relative to the proximal portion between the closed and expanded configurations.

Abstract: This disclosure relates generally to medical tubing assemblies and methods for fluid delivery from a single fluid reservoir. In one example, a tubing assembly may be configured to couple to an endoscope for distributing fluid between the endoscope and a fluid reservoir during an endoscopic procedure. The assembly may comprise a tubing manifold, a cap configured to be removably attached to the fluid reservoir, a portion of gas supply tubing and lens wash supply tubing in fluid communication between the manifold and the endoscope, a portion of gas supply tubing in fluid communication between the cap and the manifold, and a portion of lens wash supply tubing in fluid communication between the fluid reservoir and the manifold. Further examples may include portions of irrigation supply tubing and portions of alternate gas supply tubing selectively connectable in fluid communication between the manifold, fluid reservoir and endoscope.

Abstract: A steering system for a medical device may include a first drive member having a central longitudinal axis; a central shaft extending through the first drive member; a control knob coupled to the first drive member; a braking knob coupled to the central shaft and including a first protrusion; and a brake shoe member coupled to the central shaft between the control knob and the braking knob. The first protrusion may be positioned within a first channel of the brake shoe member; the first protrusion may be configured to engage the brake shoe member to move a first arm of the brake shoe member radially outward towards a wall of the control knob when the braking knob is rotated in a first direction; and the first arm may be configured to move away from the wall when the braking knob is rotated in a second direction.

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.
