Tavi System

Balloon expandable aortic valve systems –
- for Rheumatic and Degenerative patients
  • Non-occlusive deployment, allowing free blood flow
  • No rapid pacing required
  • Tactile feedback confirms ideal positioning during procedure
  • Stabilizes roots of hyper-dynamic, high-output hearts in AR

Tavi Delivery Device

Intuitive, tactile insertion device
  • Non occlusive, self homing, trans-apical delivery
  • No rapid pacing required
  • Maintains coronary perfusion
  • Backflow protected
  • Easy retrieval
  • Sheathless insertion

Self Homing - Rotational and axial alignment
Invaginating allowing frictionless retraction

Non-occlusive and back-flow protected

Paradigm-Shifting

Size Range

Valve Leaflets

The new generation of durable bioprosthetic and polymeric leaflets
  • Designed for degeneration resistance
  • Immune quiescent
  • Minimises suspension stress
  • Mass producible

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
