Bioresorbable stent

A bioresorbable stent is a tube-like device (stent) 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.

In medicine, a stent is any device which is inserted into a blood vessel or other anatomical 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 bioresorbable stent (also called bioresorbable 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.
