  • And then, in the late 1990s and early in the last decade, the medical device industry developed carotid stents to prop open the crucial blood vessel leading to the brain. (healthworkscollective.com)
  • An intraluminal coronary artery stent is a small, self-expanding, stainless steel mesh tube that is placed within a coronary artery to keep the vessel open. (mountsinai.org)
  • Your doctor will make a small cut in a blood vessel in your groin and thread a thin, flexible tube called a catheter to the place in your body where you need a stent. (mountsinai.org)
  • A plastic self-expanding stent (Polyflex, Boston Scientific) has also been developed for similar applications. (wikipedia.org)
  • The Palmaz-Schatz stent was a balloon-expandable and slotted-tube type stent manufactured using 316 L stainless steel. (medscape.com)
  • These devices differ from each other with respect to composition (eg, stainless steel, cobalt chromium alloy, nickel chromium alloy), architectural design, and delivery system (ie, a balloon catheter that delivers the stent, self-expanding, or balloon expandable). (medscape.com)
  • A metal stent is often placed across the artery wall to keep the artery from narrowing again. (medlineplus.gov)
  • All these features address issues faced by plastic and uncovered metal stents. (wjgnet.com)
  • A coronary artery stent is a small, self-expanding, metal mesh tube. (medlineplus.gov)
  • Most stents are made of metal or plastic mesh-like material. (mountsinai.org)
  • One stent, called an intraluminal coronary artery stent, is a small, self-expanding, metal mesh-like tube that is placed inside a coronary artery after balloon angiography. (mountsinai.org)
  • Either plastic or metal stents may be used. (medscape.com)
  • Metal stents are more expensive but expand to a larger diameter and tend to stay patent longer. (medscape.com)
  • Strut spacing, thickness, luminal protrusion, and malapposition were systematically investigated and a comparison made between two commercially available stents (Omega and Biomatrix). (researchgate.net)
  • For the Biomatrix stent, the adverse effect of thicker struts was mitigated by greater strut spacing, radial cell offset and flow-aligned struts. (researchgate.net)
  • An alternative strategy is the use of a flow diverting stent, i.e. a bare stent with high strut density. (springer.com)
