Polymeric Leaflets

  • Biostable polymeric leaflets
  • Designed for extended life-span compared to bioprosthetic valves
  • Thin leaflets allow lower crimp profile
  • Polymer stent encapsulation reduces leaflet stress
  • Continuous line of attachment ensures longevity

DURABILITY of SAT Polymer Leaflets

Reduced Biodegradation
25 Weeks of accelerated In-Vivo Corrosion (both images equal magnification x5000)

Bioprosthetic Leaflets

97% reduction in calcification:
  • Greatly enhanced biostability through:
    • Unique decellularization process
    • Long and short range (triple) crosslinks
    • Replacing unstable double bond with stable saturated bond
  • Continuous line of leaflet attachment ensures stress reduction
