A new approach is proposed for fatigue prediction in medical engineering of multifunctional microforceps-scissors (MFS), transconjunctival sutureless vitroretinal metal surgical instrument that removes, grasp, chops tissues and inserts new in a cell. Cyclic loads can result in the fatigue failure of MFS at stress levels below the yielding stress of material. Hence, research of the material and mechanical...
Biocompatible cardiovascular stents are small cylindrical support structures introduced into the stenosed arteries to reopen the lumen and to restore blood flow in treating heart disease, which have revolutionized interventional cardiology. Cardiovascular stent designers are confronted with two basic requirements, such as an "infinite" life and the "thinnest" wires. Pulsatile pressure,...
