In medicine, a stent is a tube or other device placed in the body to create a passage between two hollow spaces, and stenting is the placement of a stent.
A stent is a wire metal mesh tube used to prop open an artery during angioplasty. The stent is collapsed to a small diameter and put over a balloon catheter. Itâs then moved into the area of the blockage. When the balloon is inflated, the stent expands, locks in place and forms a scaffold. This holds the artery open.
