Microstent
Microstent is a term used for ultrafine intravascular stents designed for the microvasculature and small-diameter lumens in various organs. They aim to scaffold narrow vessels while minimizing flow disturbance and healing disruption. Applications span peripheral, coronary microvasculature, and certain neurovascular contexts, depending on device design and regulatory status.
Most microstents use materials such as nitinol, stainless steel, or cobalt-chromium and may feature thin struts,
Common indications include disease in distal small-caliber arteries or microchannels where conventional stents are unsuitable. They
Delivery involves catheter-based navigation to the target lumen and controlled deployment, followed by antiplatelet therapy and
Safety considerations include thrombosis, restenosis, fracture, or embolization. Evidence varies by device and indication; many microstents
The development of microstents reflects ongoing miniaturization in endovascular therapy, aided by advances in materials, coatings,
