What is an EverFlex stent

The EverFlex™ self-expanding peripheral stent system (EverFlex stent) is a self-expanding Nitinol stent system intended for permanent implantation. The self-expanding stent is made of a nickel titanium alloy (Nitinol) and comes pre-mounted on a 6 F, 0.035” over-the-wire delivery system.

What is a protege stent?

The Protégé™ GPS self-expanding peripheral stent system is a self-expanding Nitinol stent system intended for permanent implantation. The Protégé GPS self-expanding stent (Protégé GPS stent) is made of a nickel titanium alloy (Nitinol) and comes pre-mounted on a 6 F 0.035” over-the-wire (OTW) delivery system.

What is EverFlex used for?

INDICATIONS FOR USE The EverFlex Self-Expanding Peripheral Stent System .is intended to improve luminal diameter in the treatment of symptomatic de-novo or restenotic lesions up to 180mm in length in the native Superficial Femoral Artery (SFA) and/or proximal popliteal arteries with reference vessel diameters ranging …

Is self-expanding stent drug eluting?

The use of third-generation drug-eluting stents (DES) is currently the preferred method of treatment for different indications in patients with coronary artery disease. Self-expanding stents are routinely used in peripheral arterial disease, like external iliac and femoropopliteal percutaneous interventions.

What is a smart stent?

Researchers have developed a type of ‘smart stent’ that monitors even subtle changes in the flow of blood through the artery, detecting the narrowing in its earliest stages and making early diagnosis and treatment possible.

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 leg stents MRI compatible?

MAGNETIC RESONANCE IMAGING (MRI) INFORMATION : Non-clinical testing has demonstrated the Express LD Stent in single and overlapped conditions is MR Conditional. It can be scanned safely, immediately after placement of this implant, under the following conditions: • Static magnetic field of 1.5 Tesla or 3.0 Tesla.

What are the disadvantages of stents?

• Re-narrowing of your artery. When angioplasty is combined with drug-eluting stent placement, there’s a small risk the treated artery will become clogged again. …
• Blood clots. Blood clots can form within stents even after the procedure. …
• Bleeding. You may have bleeding in your leg or arm where a catheter was inserted.

Which stent is self expanding?

The STENTYS stent is self-expanding and one size covers a range of vessel diameters, which makes sizing during the procedure easier.

Are Cypher stents MRI safe?

Miami, FL – The FDA has decided that recipients of the Cypher sirolimus-eluting stent (Cordis/Johnson & Johnson) can safely undergo MRI immediately following stent implantation.

What is a smart stent and how does it work?

The smart stent integrates a micro-pressure sensor developed for chronic tracking of local blood pressure. The stent itself is designed to work as a radio-frequency antenna, in addition to its mechanical role as a vascular scaffold, for wireless telemetry of local blood pressure.

Are drug eluting stents MRI safe?

Drug-eluting stents are now used in over 80% of patients with coronary artery disease. Through nonclinical testing, the Endeavor stent has been shown to be MRI safe at field strengths of 3T or less and a maximum whole-body averaged specific absorption rate (SAR) of 2 W/kg for 15 minutes of MRI.

What is a stent card?

A stent card is a very handy way to do that. It’s a card that you carry in your wallet that tells the location of the stent in your body, the date of your procedure when you received the stent and your doctor’s name and contact information.

Why do I have to carry a stent card?

Can I travel with a coronary stent? Patients with a stent can feel confident and safe when traveling. It’s important to carry your Medical Device ID card when traveling as it will alert medical and security personnel that you have an implanted stent.

Are all stents drug-eluting?

Drug-eluting stentICD-9-CM00.55MeSHD054855

When were drug-eluting stents first used?

Eduardo Sousa implanted the first sirolimus-eluting stent in 1999 and it became available for clinical use as CYPHER® (Cordis) stent in 2002.

Why are drug-eluting stents better?

Drug-eluting stents prevent a coronary artery from narrowing again after angioplasty. They are coated with medicine that prevents scar tissue from growing into the artery.

How do self expandable stents work?

Nitinol stents are manufactured to a size slightly larger than the target vessel size and delivered constrained in a delivery system. After deployment, they position themselves against the vessel wall with a low, “chronic” outward force. They resist outside forces with a significantly higher radial resistive force.

Is Innova stent drug eluting?

Additionally, the Innova stent platform serves as the foundation for the new Eluvia drug-eluting vascular stent, which is designed specifically for the SFA.

Are stents flexible?

Stent types Common sites treated with vascular stents include the carotid, iliac, and femoral arteries. Because of the external compression and mechanical forces subjected to these locations, flexible stent materials such as nitinol are used in a majority of peripheral stent placements.

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 foreshortening stent?

Stent foreshortening defined as the difference between the desired and the actual stent length after deployment is a part of these studies. Cases with radiologic overt stent compression and elongation after deployment are reported and termed longitudinal stent deformation (LSD) [4].

How many stents can a person have?

Patients Can’t Have More Than 5 To 6 Stents In Coronary Arteries: A Myth.

How long does a stent last?

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.

What are the signs of stent failure?

Symptoms will usually tell you if there’s a problem. If that happens, you usually have symptoms—like chest pain, fatigue, or shortness of breath. If you do have symptoms, a stress test can help your doctor see what’s going on. It can show if a blockage has returned or if there’s a new blockage.

Are bare metal stents safe for MRI?

MRI information has been obtained for many bare metal and drug eluting coronary artery stents, which have been reported to be acceptable for patients undergoing MR procedures at 3-Tesla or less (i.e. based on assessments of magnetic field interactions and MRI-related heating).

Is Des MRI compatible?

While none of the stents in their study was drug eluting, Gerber and Berger say MRI would be as safe for drug-eluting stents as for bare stents.

What are bare metal stents made of?

Current bare metal stents (BMSs) are made of stainless steel, cobalt chromium, or platinum chromium. Stainless steel BMSs were the first devices used for coronary stenting.

How long does the drug last in a drug-eluting stent?

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.
