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 medication is in drug eluting stent?

Paclitaxel-eluting or sirolimus-eluting stents to prevent restenosis in diabetic patients. N Engl J Med.

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).

How long do bare metal stents last?

A stent is permanent. 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.

Do magnets affect stents?

Conclusion: The magnetic force on the investigated paramagnetic stents is even smaller than the gravitational force acting on the stents in the Earth’s gravity field, so that it has no physiological impact on the stented vessels.

Can heart stents last 20 years?

Stents are made to be permanent and will continue to keep your artery open once they’ve been placed. However, stents don’t cure the underlying condition that caused the buildup in your artery (atherosclerosis). You’ll still need treatment to prevent future artery narrowing.

What is the life of a medicated stent?

What is the mechanism of action of paclitaxel?

Mechanism of action of paclitaxel. Paclitaxel targets microtubules. At high concentration, PTX causes mitotic arrest at G2/M phase whereas at low concentration, apoptosis is induced at G0 and G1/S phase either via Raf-1 kinase activation or p53/p21 depending on the dose concentration.

Can I get an MRI if I have a stent?

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

Can you have a CT scan if you have a stent?

Mammography, CT scanning, x-rays and nuclear stress tests are considered safe for people with stents.
