Claim 9:
10. A method of draining a fluid from a catheter to a collection container, comprising:
draining a fluid along a longitudinal axis of a connector, from a distal drainage lumen through a piston housing to a proximal drainage lumen, the piston housing having an inlet and a piston, the piston slidably engaged with the piston housing between a first position and a second position, the piston in the first position occluding an inlet end of a pneumatic lumen extending between the inlet and the proximal drainage lumen, a central axis of the pneumatic lumen extending at an angle of between 20° and 70° relative to the longitudinal axis of the connector;
applying a pressurized fluid to an inlet of the connector;
sliding the piston along a transverse axis from the first position to the second position;
occluding fluid flow between the distal drainage lumen and the proximal drainage lumen; and
providing fluid communication through the pneumatic lumen between the inlet and the proximal drainage lumen, the pneumatic lumen extending external to the piston housing.
