In medicine, a stent is any device which is inserted into a blood vessel or other internal duct to expand it to prevent or alleviate a blockage. Traditionally, such devices are fabricated from metal mesh and remain in the body permanently or until removed through further surgical intervention. A<unk>  (also called<unk>  scaffold, biodegradable stent or naturally-dissolving stent) serves the same purpose, but is manufactured from a material that may dissolve or be absorbed in the body.
