Difference between balloon-expanded (BX) and self-expanding stents (SX).

Self-Expanding Stent	Balloon-Expanded Stent
Manufactured in expanded state	Manufactured in crimped state
Self-expansion due to stored elastic energy	Expansion using balloon inflation pressure
Expansion cannot be manually controlled	Expansion is a controlled process
No plastic deformation	Permanent plastic deformation
Used in bigger arteries and as valve replacement devices	Typically used smaller vessels like coronary arteries
Nitinol, shape-memory polymers, etc.	Stainless steel, Co-Cr, Platinum alloys, etc.
