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 test ed was compatible with currently available microcatheters, but its tip was considerably stiff and of limited radiopacity. Poor image quality and diffi cult image interpretation were further drawbacks. Intensive efforts are dir ected at addressing current limitations and testing further innovations tha t could pave the way for future performance in neurovascular endoscopy.
