The catheter/stent system is introduced into the body by penetrating a peripheral artery (an artery located in the arm or leg) and passed through the arterial system to deliver the DES into the blocked coronary artery. The stent is then expanded to dilate (open) blocked or narrowed coronary arteries (narrowed by plaque buildup), caused by a ...
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 placed during a coronary angioplasty.The most common use for coronary stents is in the coronary arteries, into which a bare-metal stent, a drug-eluting stent, a bioabsorbable stent, a dual-therapy stent (combination of both drug and bioengineered stent), or occasionally a covered stent is inserted.
The FDA approved the Minima stent to treat two heart conditions: coarctation, or narrowing of the aorta, which is the largest blood vessel in the body; and stenosis, or narrowing and hardening, of ...
