Abstract:

A medical device comprises a tube to be inserted into a patient. The tube has a proximal end and a distal end and provides a first fluid into the patient's body from a fluid source via a lumen. The device includes a suction port on the tube which is configured to remove a second fluid from within the patient's body via a suction lumen. The device includes an inflatable cuff that is coupled to the outer surface of the tube. The cuff is positioned adjacent to the suction port and maintains the suction port a distance away from patient tissue. In an embodiment, the cuff is cylindrical and has an inner surface which extends from the proximal side toward the distal side, wherein the inner surface is tapered such that a diameter of the inner surface with respect to the tube decreases from the proximal side toward the distal side.
