What is a Taxus stent?
By Daniel Avila
What is a Taxus stent?
The TAXUS Express Stent was designed by coating the Express® Stent with the drug paclitaxel, and the polymer. The paclitaxel/polymer coating has been designed to allow for a consistent and controlled release of the drug from the stent surface into the artery walls, to minimize release into the blood stream.
How many years is a stent good for?
How long will a stent last? It is permanent. There is just a 2–3 per cent risk of narrowing coming back, and if that happens it is usually within 6–9 months. If it does, it can potentially be treated with another stent.
Which coronary stent is best?
Today, new and improved versions of drug-eluting stents are considered safe and effective in most instances, when used with anti-clotting medication as prescribed. In general, drug-eluting stents are less likely to cause restenosis than are bare-metal stents.
What is the rate of stent?

Are Taxus stents MRI safe?
TAXUS Express Paclitaxel-Eluting Coronary Stent Through nonclinical testing, the TAXUS Express stent has been shown to be MRI safe at field strengths of 3T or less and a maximum whole-body averaged SAR of 2 W/kg for 15 minutes of MRI. The TAXUS Express stent should not migrate in this MRI environment.
Why is paclitaxel used in stents?
Paclitaxel is released from the balloon or stent to prevent scar tissue formation in the blood vessel that can re-obstruct the artery (restenosis).
Can I get an MRI if I have a stent?
All current stents are MRI safe and MRI can be done anytime.
What is paclitaxel eluting balloon?
Background. Paclitaxel-coated balloons (DCB) are suitable to reduce the risk of restenosis after angioplasty of atherosclerotic femoropopliteal lesions. However, numerous types of DCBs are distinguished by drug density and coating. Conflicting evidence exists about the risk of mortality.
What is the role of paclitaxel in the pathophysiology of taxtaxus stents?
Taxus stents carried paclitaxel, a highly lipophilic drug interfering with microtubule dynamics during mitosis (Drachman et al., 2000;
What is the difference between the Taxus and Cypher stents?
It is important to note that the majority of drug loaded on to the Taxus stent is in fact permanently retained within the polymer and is therefore not released from the stent. In contrast, near-complete release of sirolimus is achieved with the Cypher stent.
What is a polymer-free paclitaxel-eluting stent?
One of the first polymer-free paclitaxel-eluting stents to reach clinical evaluation was the V-Flex Plus stent (Cook Inc.). In this device, a coating of paclitaxel is applied directly to the abluminal facing surface of the stent.
How is the Cypher stent coated?
The Cypher stent employs a three-layer coating, comprising a base layer of Parylene C which is first applied to the metal stent to promote adhesion of the sirolimus containing middle layer [ 73 ]. This layer contains sirolimus mixed within a combination of two co-polymers, polyethylene-co-vinyl acetate and poly-n-butyl methylacrylate.
