Abstract: A device for delivering an agent may comprise: a housing defining an enclosure. The housing may be configured to store an agent. The device may further comprise an inlet, in fluid communication with the enclosure, for receiving a flow of pressurized fluid; an outlet in fluid communication with the enclosure; and a filter disposed within the enclosure. Pores of a wall of the filter may be configured such that the fluid is permitted to pass through the pores into a channel defined by an inner surface of the wall. An actuation member may be configured to transition between a first configuration, in which portions of the agent disposed proximally to the actuation member are prevented from passing distally of the actuation member, and a second configuration, in which portions of the agent disposed proximally of the actuation member are capable of passing distally of the actuation member.

Abstract: Implementations of a delivery device and method are disclosed. One implementation is a delivery device comprising a flow chamber with an inlet port for receiving a fluid flow in the flow chamber, and an outlet port for exiting a material from the flow chamber. The flow chamber may include a formation portion in which a suspension of the material is formed, and a collection portion that directs the suspension toward and/or into the outlet port. An amount of the material may collect in the collection portion adjacent the outlet port. The device may further comprise an insertion port for permitting insertion of the material in the flow chamber, and/or a pusher operable to move the amount of material through the outlet port. Related devices and methods also are disclosed.

Abstract: Systems and methods of delivering a patch to a target site of a patient are described herein. The patch may comprise a biomaterial such as chitosan or extracellular matrix and may be biocompatible and/or bioresorbable. The system may include an endoscope, a patch, and one of an instrument or a cap, the patch being coupled to the respective instrument or cap and detachable therefrom. Methods of delivering the patch to the target site may include introducing an endoscope into a gastrointestinal tract of a patient, e.g., the patch being in a folded or crimped configuration, navigating a distal end of the endoscope proximate a target site; and applying the patch to the target site while releasing the patch from the endoscope.

Abstract: A valve assembly for a medical device that includes an enclosure to store an agent, a funnel coupled to the enclosure, and configured to receive the agent via an opening of the enclosure, and a valve fluidly coupled to the enclosure and the funnel. The valve is at least partially disposed between the enclosure and the funnel, and at least a portion of the agent is received on the valve. The valve is configured to move from a first position to a second position relative to the enclosure and the funnel to selectively release the agent from the enclosure into the funnel. In the first position, the valve is configured to close the opening and inhibit the agent from exiting the enclosure and entering the funnel. In the second position, the valve is configured to open the opening and release the agent from the enclosure for delivery into the funnel.

Abstract: A valve assembly for a medical device that includes an enclosure for storing an agent and a funnel downstream of the enclosure for receiving the agent. The enclosure including a first end and the funnel including a second end positioned adjacent to the first end. The valve assembly including a first plate coupled to the enclosure at the first end, and a second plate coupled to the funnel at the second end. The first plate including at least one opening, and the second plate including at least one opening that is in fluid communication with the opening of the first plate. The first and second plates are positioned against one another, and an exterior surface of the first or second plate includes textured surface elements configured to displace the agent stored in the enclosure in response to the first or second plate moving relative to one another.

Abstract: A delivery device may comprise a sheath configured to be inserted into a body lumen of a patient. The sheath may have a proximal end, a distal end, a first channel extending within the sheath from the proximal end to the distal end, and a second channel extending within the sheath from the proximal end to the distal end. A collective cross-sectional area of the first channel and the second channel may be more than 50% of a total cross sectional area of the sheath. The device may also be comprised of a handle at the proximal end of the sheath, wherein the handle is configured to provide fluid communication between a first port and the first channel and a second port and the second channel.
