Vascular treatment and methods include a plurality of self-expanding bulbs and a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. The light from the reflective LED 301 as a light source is applied toward the surface of the recording material 304, and the reflected light from the recording material 304 is collected via the lens 303 and an image is formed on the CMOS area sensor 211. The pry element further includes an engaging surface that acts upon an inside surface of the annular lip of the bottle cap to forcibly engaged with the annular lip to prevent the opener from slipping off of the bottle cap. The actuating portions have generally flat internal electrode layers arranged inside the electromechanically active material directed substantially perpendicular to the first direction. The inventory control system involves locating backflush and intermediate backflush locations on the production path and deduct points in the material flow sequence.
