0 One of the tiniest tools implanted in the body is a coronary stent, an inflatable tube composed of synthetic or metal material. It is put into the narrowed or obstructed coronary arteries to improve blood flow to the heart muscle, thus preventing complications such as heart attacks or heart failure. Coronary stents are placed in people whose significant obstructions cannot be managed with medication.
The stenting process starts with the doctor first guiding a catheter-thin, flexible tube-through an artery in either the wrist or the groin to the blockage site. Then, at the blockage site in the heart, a small balloon is inflated, expands the coronary stent and pushes the plaque against the artery walls. When the stent has been positioned, it deflates the balloon and withdraws from the patient’s body, allowing the coronary stent to keep the artery open.
