Patent ID: 8641665

Claim:
A drainage catheter, comprising: a body including a proximal end and a distal end; a drainage lumen extending between the body proximal end and the body distal end, including a distal fluid inflow port and a proximal fluid drain coupling; an inflation lumen extending between the body proximal end and the body distal end, conveying inflating fluid from a proximal fluid supply element to a distal fluid acceptor balloon, the proximal fluid supply element adjacent the proximal fluid drain coupling; a polymeric control device positioned between the inflation lumen and the proximal fluid supply element, the control device comprising: a plug portion including a tapered outer surface and a lumen; and a stem portion detachably connected to the plug portion, the stem portion closing a proximal opening of the lumen to prevent fluid from the proximal fluid supply element from entering the lumen; a sleeve secured about the proximal fluid supply element and the proximal fluid drain coupling to provide a fluid impervious coating; and a valve connected to the proximal fluid supply element, the valve extending outside of the sleeve.
