Abstract
An atherectomy device includes a transparent lumen for providing inflation medium to an inflatable balloon. A dual lumen flexible tube includes an opaque flexible torque member in a first lumen, while the second lumen serves as an inflation lumen. The distal end of the inflation lumen is expanded to define the balloon, and no seals are needed between the balloon and the inflation lumen.
