Abstract: A valve assembly for a medical device including a container including a first region and a second region, a first fluid inlet fluidly coupled to the first region, a second fluid inlet fluidly coupled to the second region, and a piston assembly disposed within the container. The container is configured to house an agent within the second region, the first fluid inlet is configured to deliver a first portion of pressurized fluid to the first region at a first pressure level, and the second fluid inlet is configured to deliver a second portion of pressurized fluid to the second region at a second pressure level that is less than the first pressure level. The piston assembly includes a valve configured to move from a first position to a second position in response to the piston assembly moving relative to the container.

Abstract: A valve assembly that includes an inlet that is in fluid communication with an enclosure of a medical device, an outlet that is in fluid communication with a delivery conduit of the medical device, and a body having a channel that is in fluid communication with a source of fluid. The body is configured to move relative to the inlet and outlet to selectively fluidly couple the channel with the enclosure and delivery conduit. In a first position of the body, the channel is misaligned with at least one of the inlet or the outlet, such that the delivery conduit is not in fluid communication with at least one of the enclosure or the source of fluid. In a second position of the body, the channel is aligned with the inlet and outlet such that the delivery conduit is in fluid communication with the enclosure and the source of fluid.

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.
