A drug-eluting stent (DES) is a small mesh tube that is placed in the arteries to keep them open in the treatment of vascular disease.The stent slowly releases a drug to block cell proliferation (a biological process of cell growth and division), thus preventing the arterial narrowing that can occur after stent implantation.
A bioresorbable stent is a tube-like device that is used to open and widen clogged heart arteries and then dissolves or is absorbed by the body. It is made from a material that can release a drug to prevent scar tissue growth. It can also restore normal vessel function and avoid long-term complications of metal stents. [1] [2]
Coronary stents are divided into two broad types: drug-eluting and bare metal stents. As of 2023, drug-eluting stents were used in more than 90% of all PCI procedures. [1] [2] Stents reduce angina (chest pain) and have been shown to improve survival and decrease adverse events after a patient has suffered a heart attack—medically termed an ...
A dual therapy stent is a coronary artery stent that combines the technology of an antibody-coated stent and a drug-eluting stent. [1] Currently, second-generation drug-eluting stents require long-term use of dual-antiplatelet therapy , which increases the risk of major bleeding occurrences in patients. [ 2 ]
Many patients with severe but stable heart disease who routinely undergo invasive procedures to clear and prop open clogged arteries would do as well by just taking medications and making ...
Stents and shunts can be made of similar materials, but perform two different tasks. There are various types of stents used for different medical purposes. Coronary stents are commonly used in coronary angioplasty, with drug-eluting stents being the most common type. Vascular stents are used for peripheral and cerebrovascular disease, while ...
The FDA recently approved a heart stent made specifically for infants and young children, a device that could help kids born with certain congenital heart defects avoid a series of open heart ...
Older bare-metal stents (BMS) provide a mechanical framework that holds the artery wall open, preventing stenosis, or narrowing, of coronary arteries. Newer drug-eluting stents (DES) are traditional stents with a polymer coating containing drugs that prevent cell proliferation. The antiproliferative drugs are released slowly over time to help ...
