A coronary stent is a tube-shaped device placed in the coronary arteries that supply blood to the heart, to keep the arteries open in patients suffering from coronary heart disease. The vast majority of stents used in modern interventional cardiology are drug-eluting stents (DES).
It is a standard practice to have further follow-up examinations every three to six months for the first year, though these practices do vary by region and practitioners. Further diagnostic coronary angiography is not routinely indicated after coronary stent implantation. If progression of heart disease is suspected, a stress test will be ...
A stent graft or covered stent is type of vascular stent with a fabric coating that creates a contained tube but is expandable like a bare metal stent. Covered stents are used in endovascular surgical procedures such as endovascular aneurysm repair. Stent grafts are also used to treat stenoses in vascular grafts and fistulas used for hemodialysis.
The angioplasty uses the insertion of a balloon and/or stents to open up the artery. [1] Other surgeries performed are the more invasive bypass surgeries that graft arteries around blockages. If an MI is presented with ECG evidence of an ST elevation known as STEMI, or if a bundle branch block is similarly presented, then reperfusion therapy is ...
Stents, which are specially manufactured expandable stainless steel mesh tubes, mounted on a balloon catheter, are the most commonly used device beyond the balloon catheter. When the stent/balloon device is positioned within the stenosis, the balloon is inflated which, in turn, expands the stent and the artery.
Ureteral stent Ureteral stent (detail) A ureteral stent (pronounced you-REE-ter-ul), or ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney.

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]
