What is the structure of the heart stent?

At present, heart stents are basically tubular, and the mainstream material is metal. At the beginning of the year, a new bioabsorbable scaffold was made of polylactic acid. After being implanted into the body, it is degraded and absorbed by the human body for about 3 years, so that the elastic contraction function of blood vessels can be restored, the blood vessels can be reconstructed, and the "metal heart" can be bid farewell.
