1. A device for holding plaque against blood vessel walls surrounding a lumen of a blood vessel to keep the lumen open in treating atherosclerotic occlusive disease, comprising:

  • a thin, annular band made of a durable, flexible material and having a plurality of barbs on its outer annular periphery, said annular band being dimensioned with a length along a longitudinal axis of the lumen that is less than its diameter, and being designed to be applied in the lumen with an outward expansion force against the plaque to press and hold the plaque against the blood vessel walls,wherein said annular band is made of thin, flexible wire which is looped and interleaved in an annular mesh form, andwherein said plurality of barbs are formed at a plurality of points on the wire around the outer annular periphery of the annular mesh form so as to project from the annular mesh form with sharp points outwardly toward the blood vessel walls such that, when an outward expansion force is applied, the sharp points around the outer annular periphery pierce into the plaque and maintain a locking relationship relative to the blood vessel walls.
