Abstract
A balloon-expandable stent formed from a customized alloy formulation. The stent alloy has a either a high, variable or no work hardening rate, very high modulus of elasticity (Young's modulus), and a low yield point. A stent constructed of a material with this combination of properties undergoes significant plastic deformation upon deployment in vivo to its implantation diameter and exhibits minimum recoil for better sizing. The plastic deformation also raises the subsequent yield point of the stent material resulting in a stronger stent upon implantation that is more resistant to vascular loading.
