What is a Taxus stent?

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.

Are Taxus stents MRI safe?

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.

What causes stent dislodgement?

Stent dislodgement can occur due to arterial tortuosity and calcification, direct stenting, or the inadequate coaxiality of the guide catheter; therefore, adequate predilation may help to prevent stent dislodgement.

What medication is in drug eluting stent?

DES consist of a standard metallic stent, a polymer coating, and an antirestenotic drug that is mixed within the polymer and released over time. First-generation DES include sirolimus-eluting stents (SES; 2003) and paclitaxel-eluting stents (PES; 2004) (TABLE 1).

Are Xience stents MRI safe?

Non-clinical testing has demonstrated that the XIENCE Sierra stent, in single and in overlapped configurations up to 71 mm in length, is MR Conditional. It can be scanned safely under the conditions in the Instructions for Use.

Can I get an MRI if I have a stent?

All current stents are MRI safe and MRI can be done anytime.

Can a stent fail?

Failure to deliver the stent to the lesion site was the main cause in 139 patients (92%) and failure either to expand adequately the stent or premature disengagement of the stent from the balloon in only 12 patients (8%). Peripheral stent embolization occurred in 10 (0.3%) patients.

Can you lose a stent in your heart?

Because stent loss, which occurs rarely during the procedure, might have dire consequences, such as bleeding, stent embolism, acute myocardial infarction, emergency coronary artery bypass graft, and death, appropriate treatment is needed as soon as stent loss occurs.

Which is better Plavix or Brilinta?

Brilinta has been marketed and studied as a more effective drug than Plavix. It has been shown to be a better drug for reducing rates of cardiovascular death and preventing heart attack or stroke. However, it may be more likely to produce adverse effects such as bleeding and shortness of breath.

How long do drug coated stents last?

Once placed, you’ll have it for life, which your body can safely tolerate. If your arteries narrow again, you’ll need to have the procedure again to correct it. If this happens, it’s usually within the first 6 months. One newer type of drug-eluting stent completely dissolves after about 3 years.

Is Xience stent drug eluting?

XIENCE, which is also described as a drug-eluting stent (DES) or more specifically an everolimus-eluting stent (EES), is a leading DES because of its considerable safety data. XIENCE Alpine is engineered for complex intervention.

How is paclitaxel coated in the Taxus stent?

In the Taxus stent, a coating containing paclitaxel and the copolymer, poly (styrene-B-isobutylene-B-styrene) (Translute) is applied to the stent to provide sustained paclitaxel release [73 ].

Is the taxus&express stent MRi safe?

ithrough non-clinical testing, the TAXUS Express Stent has been shown to be MRI safe at field strengths of 3 Tesla or less, and a maximum whole body averaged specific absorption rate (SAR) of 2.0 W/kg for 15 minutes of MRI. The TAXUS&Express Stent should not migrate in this MRI environment.

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 the device component of the Express 2 stent?

1.1 Device Component Description -The device component consists of the Express Stent mounted onto the Express 2 Stent Delivery /stem (SDS). The 2.25 – 4.00 mm diameter 316L stainless steel stents use two designs. The stents are crimped on various delivery catheter balloons, which are sized from 2.25 to 4.00 mm.
