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.

Devices, systems, and methods for medical cleaning valves

Indicator for medical devices

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.

Braking mechanisms for steerable medical devices and related methods

A medical cleaning valve (or cleaning valve) may be configured to provide cleaning functionality to air and water channels of an endoscope. One or more embodiments described herein may include cleaning valves with features and/or components that facilitate differentiating them from procedural valves. In some embodiments, valves may be made from a limited number of parts and materials, to limit their cost. For example, multiple seals may be formed as a single component, such as via overmolding. In another example, wiper seals may be used to accommodate greater manufacturing tolerances. In yet another example, the valve may have a single elastomeric component, or spring cap, which may combine the functionality of a number of components (e.g., a boot, spring, spring housing, and stem cap).

Devices, systems, methods, and designs for medical cleaning valves

Stent delivery systems and methods for making and using stent delivery systems are disclosed. An example stent delivery system may include an inner shaft. A deployment sheath may be disposed about the inner shaft. A stent may be disposed between the inner shaft and the deployment sheath. A stent reconstraining member may be secured to an inner surface of the deployment sheath and releasably secured to the stent.

Stent delivery systems with a reconstraining member

A medical valve may comprise a valve stem and an operation portion. The operation portion may include a stationary portion, a movable portion which is movable relative to the stationary portion and fixed relative to the valve stem, a seal disposed between the stationary portion and the movable portion, and a biasing member. Movement of the movable portion in a first direction may cause deformation of the biasing member, such that a restorative force of the biasing member urges movement of the movable portion in a second direction opposite the first direction. A frictional force between the seal and one of the stationary portion and the movable portion resists the movement of the movable portion in the second direction.

Medical cleaning valve

A valve for use in an endoscope may comprise a proximal valve stem member having a first lumen extending from a proximal opening at a proximalmost end of the proximal valve stem member to a distal opening at a distalmost end of the proximal valve stem member. A distal valve stem member may have a second lumen with a proximal opening at a proximalmost end of the distal valve stem member. The proximalmost end of distal valve stem member may be received within the distal opening of the first lumen. The distal valve stem may be movable relative to the proximal valve stem.

Medical valve

A valve may have a fluid inlet and a fluid outlet. The valve may include a valve stem having a lumen extending from a first opening at a proximal portion of the valve stem to a second opening at a distal end of the valve stem. A plurality of seals may be positioned relative to the valve stem. The valve stem and seals may be configured so that a fluid entering the inlet is prevented from flowing to the outlet in a first position of the valve stem and relative to the inlet and the outlet. The valve stem and the seals may be configured so that a fluid entering the inlet flows to the outlet in a second position of the valve stem relative to the inlet and the outlet, the second position being more distal than the first position relative to the inlet and the outlet.

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.

Tubing assemblies and methods for fluid delivery

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.

Endoscope air/water flush adaptor and method

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.

Integrated container and tube set for fluid delivery with an endoscope

A stent delivery device is provided that includes an inner member defining a distal tip and a stent holding region, and an outer tubular member slidingly disposed over the inner member and configured to engage the distal tip. Seal members may be disposed on one or more of an outer surface of the inner member, the distal tip, and the outer tubular member. The seal members define a liquid-tight sealed chamber surrounding the stent holding region.
