Abstract: A device for fluidizing and delivering a powdered agent, including a canister extending longitudinally from a first to a second end and defining a space within which a powdered agent is received, an inlet coupleable to a gas source for supplying gas to the space to fluidize the powdered agent to create a fluidized mixture, an outlet via which the gas mixture is delivered to a target area, a tube extending from the outlet into the interior space, the tube including a slot extending through a wall thereof so that gas mixture is passable from the interior space through the outlet via the second end and the slot, and a door movably coupled to the tube so that the door is movable over the slot to control a size of the slot open to the interior space of the canister.

Abstract: A medical system includes a source of a material, a first tube, and a second tube. The material is configured to expand and form a porous body after the material is deployed into a body lumen. The first tube is configured to deliver the material into the body lumen, and the second tube is configured to apply suction to the porous body.

Abstract: A medical device may comprise a flexible sheath defining a lumen extending from a proximal end of the sheath to a distal end of the sheath. The sheath may include a piston slidably received within the lumen; an agent disposed in the lumen distal to the piston; and pneumatic fluid disposed in the lumen proximal of the piston. The device may also comprise handle at a proximal end of the sheath, the handle including: a plunger received in a reservoir, wherein the reservoir is in fluid communication with the lumen. The reservoir may contain pneumatic fluid. The handle may also include a gear. An amount of rotation of the gear in a first direction may correspond to an amount that the plunger advances distally in the reservoir to displace pneumatic fluid. The displacement of the pneumatic fluid may advance the piston distally to deliver an amount of agent from the sheath.
