Polymeric Leaflets

  • Biostable polymeric leaflets
  • Thin leaflets allow lower crimp profile
  • Stent encapsulation reduces stress in leaflets resulting in extended durability
  • Focus on leaflet smoothness further reduced thrombogenicity
  • Continuous line of attachment ensures longevity

Biostability of SAT Polymer Leaflets

Biodegradation
25 Weeks of accelerated In-Vivo Corrosion

Bioprosthetic Leaflets

Reduces calcification of bovine pericardium by 97% through:
  • Decellularisation and triple cross linking
  • Long and short range crosslinks
  • Replacing unstable double bond with stable saturated bond
  • Continuous line of attachment ensures continual stress reduction
