Laboratory evaluation of a microangioscope for potential percutaneous cerebrovascular applications.
A laboratory-based study of the physical and performance characteristics of a new 0.25-mm-thin microangioscope was performed. The microangioscope tested was compatible with currently available microcatheters, but its tip was considerably stiff and of limited radiopacity. Poor image quality and difficult image interpretation were further drawbacks. Intensive efforts are directed at addressing current limitations and testing further innovations that could pave the way for future performance in neurovascular endoscopy.
