This work looks to provide a review of modern stents by evaluating the need for them as well as providing a detailed engineering analysis of the conditions they are subjected to. It is estimated that over two million of these devices are implanted in patients annually. Of those implanted, a majority are used in the treatment of arteriosclerosis. This disease causes arterial walls to thicken and toughen leading to restricted blood flow and in extreme cases, complete loss of circulation. Arteriosclerosis and complications arising from it form a leading cause of death in the developed world. Although there are a variety of treatment options available, stents have been successfully used for several decades. The review of numerous technical reports infers that stents must withstand complex multi-axial loading conditions while being able to withstand an immense number of loading cycles, making the design and implementation of stents a significant feat.
