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.
