A stent is a small device inserted into a clogged artery to improve blood flow through the artery and to prevent further heart damage. This has become a common procedure for heart specialists.
A stent is a mesh 'tube' inserted into a natural passage/conduit in the body to prevent or counteract a disease-induced, localized flow constriction. The term may also refer to a tube used to temporarily hold such a natural conduit open to allow access for surgery.
