Endoscopic medical device for dispensing materials and method of use

A medical device, comprising:

• an outlet;
• a container configured to store an agent;
• a channel in fluid communication with the outlet and the container, the channel including one or more openings;
• and
• an attachment member disposed within the container and movable relative to the outlet between a first position and a second position;
• wherein, in the first position, the attachment member is configured to block the one or more openings such that the outlet is not in fluid communication with the container, thereby inhibiting the agent from exiting the container and entering the outlet via the channel;
• and
• wherein, in the second position, the attachment member is configured to unblock the one or more openings such that the outlet is in fluid communication with the container, thereby allowing the agent to exit the container and enter the outlet via the channel.

A medical device, comprising:

• an outlet;
• a container storing an agent;
• and
• an attachment member disposed within and coupled to the container, the attachment member is configured to transition the container between a closed configuration and an open configuration in response to moving relative to the outlet;
• wherein, in the closed configuration, the attachment member is positioned relative to the outlet to fluidly decouple the outlet from the container, thereby inhibiting the agent stored in the container from entering the outlet;
• and
• wherein, in the open configuration, the attachment member is positioned relative to the outlet to fluidly couple the outlet to the container, thereby allowing the agent stored in the container to enter the outlet.
