4. Average cost for medical stent
Medical stent price is expensiThe cost of a heart stent depends on its type.
Drug-eluting stents are costlier than bare-metal stents, because they slowly
release a drug that prevent in-stent restenosis.
Type Avg.cost
Bare-metal stent Less than $1000
Drug-eluting Less than $1700
Bio-engineered/dual-therapy stent Less than $4000

5. PERFORMANCE
• Very small, the minimum cell size is 2 mm. (enter the blood vessels smoothly)
• Very flexible because it suit the blood vessels shape. They can be subject to
elongation or compression during delivery.
• Non degradable - good strength and corrosion resistance
(so we do not have to replace it )
• High cell density
