Claim 0:
1. 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 source of the agent defined by a cylindrical portion and a funnel portion positioned downstream from the cylindrical portion, the cylindrical portion is configured to store the agent and the funnel portion is configured to receive the agent from the cylindrical portion via gravity;
a source of pressurized fluid disposed within the body, the cylindrical portion is in fluid communication with the source of pressurized fluid through the funnel portion; and
an actuator including a trigger that is movably coupled to the body, wherein, in response to pulling the actuator, the body, the source of the agent, and the source of pressurized fluid are arranged to deliver the pressurized fluid through the funnel portion upstream into the cylindrical portion of the source of agent to move the agent therein, and to move a mixture of the agent and the pressurized fluid out of the source of the agent and to the exit port for delivery through the channel;
wherein the actuator is configured to move a pin relative to the body and into engagement with the source of pressurized fluid, in response to selectively pulling the actuator, thereby piercing the source of pressurized fluid and releasing the pressurized fluid into the source of the agent.
