　In recent years, neuroendovascular therapy has advanced rapidly, enabling precise and minimally invasive treatments. A major driving force behind this progress is the evolution of devices, such as microcatheters, microwires, coils, and flow diverters. Understanding the specific characteristics of these devices and their appropriate use is essential to achieve optimal clinical outcomes. Current understanding is largely based on package inserts, manufacturing materials, schematic illustrations, and optical microscopy images. However, as these devices are extremely small, their true structural details are difficult to visualize.

　This article presents the direct observations of neuroendovascular devices using scanning electron microscopy, providing insights into their microscale architecture. By re-evaluating the device characteristics from this microscopic perspective, we aim to clarify their clinical significance and enhance understanding of device selection in neuroendovascular practice.
