The objective of this study is to evaluate the safety and effectiveness of the TALENT endoluminal stent-graft system in patients who may be categorized as standard risk, high risk or other indications. Standard risk patients are patients with indications for treatment that are consistent with those for a manufacturer IDE, when there is no active enrollment in the IDE. High risk patients are patients who do not meet the entrance criteria for the manufacturer sponsored IDE as they are at high risk of morbidity and mortality with standard surgical repair. Other indications would be considered patients with indications for treatment outside of those or the manufacturer sponsored IDE.
