Classification: CPC A | IPC A

Claim 14:
15. A delivery device configured to deliver an agent to a target tissue through a channel of a medical device, the delivery device comprising:
a body including (a) a coupling region configured to removably attach to a handle of the medical device, the medical device including an endoscope, and (b) a coupler including an exit port for aligning with a port of the channel, wherein the coupler is configured to mate with the port of the channel;
a pressurized fluid container within the body;
an enclosure within the body defined by a cylindrical portion and a funnel portion positioned at an end of the enclosure opposite to the cylindrical portion, and wherein the cylindrical portion is configured to store and feed the agent to the funnel portion via gravity, the funnel portion is configured to receive a pressurized fluid to move the agent within the cylindrical portion of the enclosure, and to direct and release a combination of the pressurized fluid and the agent through the exit port;
a regulator within the body and configured to control delivery of the pressurized fluid from the pressurized fluid container prior to the pressurized fluid entering the enclosure at the funnel portion, the regulator including a fluid input port coupled to the pressurized fluid container such that the pressurized fluid enters the regulator prior to entering the enclosure, wherein the pressurized fluid and the agent flows from the enclosure to the exit port upon the pressurized fluid from the pressurized fluid container entering the regulator via the fluid input port and prior to the cylindrical portion of the enclosure receiving the pressurized fluid from the regulator via the funnel portion; and
an actuator including a trigger, the actuator configured to pierce the pressurized fluid container by selectively moving a pin into engagement with the pressurized fluid container to release the pressurized fluid from the pressurized fluid container for receipt by the regulator via the fluid input port.
