Abstract
A device for clearing obstructions from a medical tube includes an elongated guide member residing at least partially with the medical tube. In a resting state, clearance members positioned along the guide member are in a low-profile configuration and allow a substantially unobstructed flow through a lumen of the medical tube. In use, the clearance members are in an enlarged-profile configuration to break up and clear obstructions from within the lumen of the medical tube.
