Considering the lipid concentration and side effects regarding the stents used by surgeons,
a new heart stent model is proposed. In the new stent, a few piezo plates are designed and
attached to the stents by which release of the lipids can take place due to the applied
alternative voltages. Due to the vibrations of small-scale piezoelectric plates, the deposition
of low-density-lipoproteins (LDL) floating in the blood flow in the coronary arteries is
prevented. Small-scale effects are considered using nonlocal elasticity theory, and the …
