VISSIT Intracranial Stent Study for Ischemic Therapy

Summary

The main objective of this study is to prospectively evaluate the safety, probable benefit, and effectiveness of the PHAROS Vitesse Neurovascular Stent System in a multicenter, randomized clinical trial. A secondary objective of this study is to evaluate the impact of stenting in the neurovasculature to treat cerebral ischemia on other outcomes such as hospital length of stay, charges, and costs.
