A suction valve for endoscopes (e.g., duodenoscopes) includes a valve element that rotates between open and closed positions in response to linear movement of a plunger. In some examples, a meshing gear arrangement provides the mechanical interaction between the plunger and the valve element. In some examples, the valve element's rotation is by virtue of at least portions of the valve element being resiliently flexible. In some examples, the valve element's resilience urges the plunger to its relaxed home position. In some examples, the axis about which the valve element rotates is parallel to the plunger's linear travel path. In some examples, the axis about which the valve element rotates is perpendicular to the plunger's linear travel path.

MEDICAL DEVICES FOR AGENT DELIVERY AND RELATED METHODS OF USE
A device may be configured to deliver an agent to a target tissue via pressurized fluid and the device may include a catheter including a lumen; an enclosure configured to store an agent, receive a pressurized fluid, and release a combination of the pressurized fluid and the agent; and a valve downstream of the enclosure to receive the combination of the pressurized fluid and the agent from the enclosure. The valve may have a first configuration preventing flow of the combination through the lumen and a second configuration permitting flow of the combination through the lumen.
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 establishing a controlled flow or access passage between body lumens. For example, a device may include an elongate tubular body defining a lumen along a length thereof. The elongate tubular body may have an unexpanded configuration and an expanded configuration.
