Abstract
An intravascular device for treating atherosclerotic occlusive disease can include an annular band defining a longitudinal axis between proximal and distal ends. The annular band can have a plurality of barbs on its outer periphery. One or more intravascular devices may be applied in positions along a plaque accumulation site as needed to stabilize the site and/or hold pieces of plaque out of the way of blood flow. The barbs may be pressed into the plaque and/or blood vessel walls.
