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 a smart stent?
Researchers at the University of British Columbia created a ‘smart stent’ empowered with sensors that can monitor and provide real-time feedback on blood flow to help decrease restenosis or the narrowing of arteries.
What is nitinol stent?
Nitinol is shape-set by deforming the sample into a desired geometrical shape, and heating it to high temperatures (on the order of 450–550 °C). Nitinol stents are shape-set in the open form so they can return to it (i.e., self-expand) when released from the catheter during deployment.
How many stents are made of Nitinol?
In the Global Data study (8) 63% of the peripheral stents profiled were made using Nitinol, and in their Nitinol Medical Devices market study, Transparency Market Research (10) estimates that over 50% of the peripheral and coronary stents currently available in the market are made from Nitinol.
What is the cost of a stent?
Specific Cardiac Stent Procedures and National Cost Averages
| Price Range | |
|---|---|
| Cardiac Stent Implantation Cost Average | $29,300 – $80,400 |
Why is Nitinol used in stents?
Most PAD stents therefore are made of self-expandable shape memory Nitinol that allows the device to expand to a pre-set shape once released from the catheter without the assistance of a balloon, and, most importantly, return to this shape after being deformed during limb flexion.
Why is Nitinol used?
In medical devices, Nitinol is popular due to its biocompatibility, superelasticity and fatigue and kink resistance (5). Nitinol is used to manufacture catheter tubes, guidewires, stone retrieval baskets, filters, needles, dental files and archwires and other surgical instruments (6).
How long can you live with a stent?
When you have a stent placed, it’s meant to be permanent. Stents can stay in your body without breaking down over time. However, stents only treat one area where your artery has narrowed or closed. They don’t treat the underlying condition of vascular disease.
