ABSTRACT:
A medical-grade, flexible tube is provided with a plurality of circumferentially and longitudinally spaced, flexible, directional anchoring protrusions for allowing the catheter to be moved lengthwise along a passage in one direction but to resist movement lengthwise out of the passage. Lateral apertures are provided at both ends of the tube for providing a fluid path into and out of the ends of the tube. An additional protrusion is provided at one end of the tube to resist lengthwise inward movement of the tube.
