Product type
A coronary stent is a small, mesh-like tube made of metal or polymer that is used to treat narrowed or blocked coronary arteries. It is typically inserted into the artery during a procedure called angioplasty, where the stent is expanded to hold the artery open, allowing for improved blood flow to the heart. Stents may be coated with medication to help prevent re-narrowing of the artery, a condition known as restenosis.

When selecting a coronary stent, buyers should consider the specific medical needs of the patient, including the size and location of the blockage. It is important to specify the required diameter and length of the stent, as well as whether a drug-eluting or bare metal stent is preferred. Certifications such as FDA approval and compliance with ISO standards are also critical factors to ensure safety and efficacy. Quantities may vary based on the healthcare facility's needs.
