Researchers at Michigan Tech are creating bioabsorbable stents with zinc and zinc alloys that could prove safer than current stent materials. Building better metallic stents to support weakened ...

Ureteral stents are commonly used in the field of urology, and, given their indwelling nature, are often a nidus for infection and a cause of discomfort. To minimize symptoms, the urologic surgeon ...

"But there's not a lot of information on exactly how stents degrade in the body," said Patrick Bowen, who just completed his bachelor of science degree in materials science and engineering at ...

Cardiovascular stent technology, related to the design, materials, coating, and many other relevant features, is evolving continuously. Study: Functionalized Fluorescent Nanodiamonds for Simultaneous ...

The project at KIST's Biomaterials Research Center investigated how the vascular cells reacted when the stent surface had been previously been laser-treated to create nano- or micro-scale wrinkles in ...

As the stent expands, it becomes locked in place permanently. Most stents are made of a mesh material to ease the process. For larger arteries, fabric stents may be used. The benefit of using a ...

Modern stent designs incorporate breakthroughs in material science, resulting in structures that are more flexible, are less likely to drive inflammation and more effectively deliver drugs to help ...

The downside of this high scaffolding rate of closed-cell geometry is the high ratio between the quantity of stent material in comparison with the amount of vessel tissue, defined as wall coverage.

Stents are permanent, according to the British Heart Foundation. Stents are made of materials meant to keep an artery open permanently, and they should last a lifetime. However, stents alone do ...

They were pulled from the market and are no longer used. These stents were made with similar material to dissolving stitches. What Are the Benefits of Drug-Eluting Stents? Drug-eluting stents have ...

Coronary stents are categorized based on the materials used in their construction, including bare metal stents, bioabsorbable stents, and drug-eluting stents. These stents can be further divided ...
