An intravascular material removal device that removes material from a vessel wall and creates flow dynamics that draw the material into a catheter device for removal from the vessel is provided. A collapsible device that provides a relatively low delivery profile while being expandable in use to adapt to varying and variable vessel diameters is also provided. A spiral configured material removing element is provided that can adapt to varying vessel diameters and to remove material forming blockages or occlusions from the inner wall of a vessel.
