Bare Metal Stents (BMS)
Overview
Bare Metal Stents (BMS) are tubular devices made of metal, typically stainless steel or cobalt-chromium, used to treat narrowed or blocked coronary arteries. They are inserted into the artery to hold it open and restore proper blood flow. Unlike Drug-Eluting Stents (DES), BMS do not have a coating that releases medication, which makes them simpler but with a higher risk of restenosis (re-narrowing of the artery) compared to DES.
Attributes
- Material: Stainless steel or cobalt-chromium.
- Design: Mesh-like tube structure that provides scaffolding to the artery.
- Usage: Primarily used in coronary arteries but can also be used in peripheral vascular procedures.
- Diameter and Length: Vary to suit different artery sizes and lesion lengths.
- Flexibility and Radial Strength: Designed to provide optimal balance between flexibility (for easier navigation through arteries) and radial strength (to keep the artery open).

Conclusion
Bare Metal Stents play a crucial role in interventional cardiology by providing a mechanical solution to keep arteries open. Each brand and manufacturer offers specific models designed to cater to various clinical needs, and the choice of a particular stent can depend on the patient's condition, the anatomy of the artery, and the physician's preference.
