Abstract
A sheath comprises an elastomeric tube having a self-expanding scaffold coupled to a wall. The scaffold can expand to a diameter larger than the tube diameter to provide an enlarged distal opening. An aspiration catheter has a balloon and an aspiration port so that occlusive material can be removed from a blood vessel by drawing the balloon through the vessel while simultaneously aspirating through the port.
