Abstract

Abstract The present invention provides an implantable device for use in the treatment of at least partially obstructed body lumen. The implantable medical device includes at least one radiopaque tubular section attached to a first end of a tubular midsection. Upon viewing the device with x-ray, a three dimensional image is visible that allows for increased accuracy in assessing device placement, device sizing, device deployment, and even lumen orientation.
