Abstract

A stent which may be emplaced into the lumen of the body. The stent has an expandable first section with a first diameter and an expanded second diameter larger than its first diameter. There is also a second section connected to the first section, the second section contains a third diameter and an expanded fourth diameter which is larger than the third diameter. Finally, the second diameter is different from the fourth diameter. Thus, the device may be emplaced between lumens of different sizes. Ideally, this stent can be placed at the junction at the aorta and the iliac arteries, where the size of the lumens are typically different. In use, therefore, the device provides the surgeon with a useful tool to holding open junctions of various sized lumens.
