Abstract
The tubular unit with vessel engaging cuff structure is a unitary unit including a tube having a compressible cuff surrounding the outer surface thereof. The cuff includes a resilient, porous inner material surrounding the tube and an outer liquid impervious layer which may be bonded to or integrally formed with the inner material. The tube may include means to evacuate fluid from the cuff or, alternatively, separate means are directly connected to the cuff to accomplish such evacuation and contraction of the cuff. Vessel engaging appendages may be incorporated on the cuff.
