Are there different sizes of stents?
Stents range from 8 to 38 mm in length and from 2.5 to 4.0 mm in diameter. Stents differ in interunit connections, flexibility, radiopacity, surface area coverage, metal content, and metal composition (although the overwhelming majority are 316L stainless steel) (Figure 1).
How do you size a stent?
In general, there are two ways to size coronary stents by the IVUS technique. The traditional IVUS method requires measurement of the maximum proximal and distal reference lumen diameters by IVUS. The stent size is selected based on the larger of these measurements.
What is the smallest stent?
Following FDA approval, Resolute Onyx 2mm becomes smallest stent on US market. Designed specifically for small vessels, the Resolute Onyx 2mm drug-eluting stent has received US FDA approval and, consequently, has been launched on to the US market.
How big is a stent in inches?
It usually measures 2–3 mm (1/8 inch) in diameter. Once the sheath is in place, the balloons and stents are all passed through this sheath. A very thin tube is then passed through the sheath into the narrowed artery and an angiogram picture is taken.
What is the normal length of a stent?
The average stent length was 15.45 mm in BMS and 16.83 mm in DES (p=0.0026). The average stent diameter was 3.00 mm in BMS and 2.89 mm in DES (p=0.00027).
What happens if a stent is too small?
Larger stents induce more trauma to vessels and therefore more intimal hyperplasia, more edge dissections and more coronary ruptures. Conversely, underexpanded stents increase both the risk of restenosis and the likelihood of stent thrombosis.
Can you stent small arteries?
The smallest drug-eluting stent (DES) available in the United States has received FDA approval. At 2.0 mm, the new stent is intended to help interventional cardiologists treat patients with coronary artery disease whose small vessels often can’t be treated with larger stents during percutaneous coronary intervention.
What is the average length of a stent?
The average stent length was 15.45 mm in BMS and 16.83 mm in DES (p=0.0026). The average stent diameter was 3.00 mm in BMS and 2.89 mm in DES (p=0.00027). The niumber of stents per patient was 1.58 for BMS and 1.50 for DES (p not significant).
How thick is a stent?
Consequently, there has been a move to the use of stents with minimal strut thickness, with current stents typically employing metal struts ranging in thickness from around 60 to 100 μm.
What is the stent size for resolute integrity des products?

What is resolute™ integrity zotarolimus-eluting coronary stent?
The Resolute™ Integrity Zotarolimus-Eluting Coronary Stent System is indicated for improving coronary luminal diameters in patients, including those with diabetes mellitus, with symptomatic ischemic heart disease due to de novo lesions of length ≤ 27 mm in native coronary arteries with reference vessel diameters of 2.25 mm to 4.20 mm.
What is the Resolute™ stent made of?
The Resolute Onyx™ stent is comprised of a bare metal stent with a Parylene C primer coat and a coating that consists of a blend of the drug zotarolimus and the BioLinx® polymer system. BioLinx® is a blend of the Medtronic proprietary components C10 and C19, and PVP (polyvinyl pyrrolidone).
