MANUFACTURING PROCESS OF A TUBULAR STENT HAVING A SLIGHT RESISTANCE TO CRUSHING

摘要

The invention relates to a stent for implanting in a blood vessel in its deployed state, aided by the expansion of a balloon. Said stent is obtained by cutting a tube from non-corrosive steel. The radial force of the stent once it has been implanted and deployed is slightly greater than the elastic retraction of the blood vessel. The resistance to crushing of a stent for implanting in a coronary artery for example, is 0.2 105 Pa (0.2 bar).
