Evaluation of Safety and Efficacy of NvisionVLE® Imaging Low Profile System in Patients With Bile Duct Disease

The primary objective of this retrospective and prospective study is to acquire additional data to further evaluate the safety and efficacy of the NvisionVLE® Imaging Low Profile System in patients with bile duct disease. The secondary objective will be to provide a tool for participating physicians to collect imaging data, clinical utility data, and other clinical data such as demographics, pathology, and treatment surveillance results for patients who have undergone an examination of the bile duct with the NvisionVLE® Imaging Low Profile System. Specific aims include completing a multi-center registry to further evaluate the safety and efficacy of the NvisionVLE® Imaging System Low Profile System and developing a tool from the NvisionVLE® Imaging Low Profile System data to better define abnormalities, target sampling and therapy in patients with bile duct disease.
