1. A medical device, comprising:
a valve set including a primary control valve, an air input valve, and an atmospheric valve, the primary control valve configured to control flow between the water input channel, the water output channel, and the balloon channel of the valve well, the air input valve configured to control flow through the air input channel of the valve well, and the atmospheric valve configured to control flow through the atmospheric channel;
a valve interface mechanism including a set of one or more biasing members and a user interface mechanism, the user interface mechanism comprising a toggle coupled to a cam comprising a plurality of steps, the toggle operable between a first state, a second state, a third state, and a fourth state, the first state comprising the valve set configured to place the air input channel in fluid communication with the atmospheric channel, the second state comprising the valve set configured to place the air input channel in fluid communication with an air output channel, the third state comprising the valve set configured to place the water input channel in fluid communication with the water output channel, and the fourth state comprising the valve set configured to place the water input channel in fluid communication with the balloon channel,
wherein in the first state the air input valve permits flow through the air input channel and atmospheric valve permits flow through the atmospheric channel,
wherein in the second state the air input valve permits flow through the air input channel and the atmospheric valve blocks flow through the atmospheric valve,
wherein in the third state the primary control valve permits flow from the water input channel to the water output channel and the air input valve blocks flow through the air input channel,
wherein in the fourth state, the primary control valve permits flow from the water input channel to the balloon channel and the air input valve blocks flow through the air input channel,
wherein the cam is configured to translate the motion of the toggle into linear motion of the primary control valve, and
wherein each of the plurality of steps of the cam causes a different amount of linear motion of the primary control valve.
