ABSTRACT
In medicine, the procedure of carotid stenting has arisen from trials of stenting to do a simple balloon angioplasty in the carotid arteries. This procedure consists of fitting a stent inside a carotid artery to increase the flow of blood blocked by plaques. After this a ballon-tipped catheter is inserted to inflate the artery and reopen it. The stents act as a scaffold to prevent the artery from collapsing or being closed by plaque after procedure. Biomaterials for artificial organs inside our body must be biocompatible should not cause reactions or side effects in the human body. The ballon-tipped catheter and stents need to be wear resistant and elastic to fulfill the purpose. Threfore, the biomaterials for a stent should be selected after a thorough study.
