Simulus Flexible Annuloplasty System

Simulus Flexible Annuloplasty System

The Simulus® Flexible Annuloplasty System provides flexible support for physiological mitral and tricuspid valve repair.


The Simulus Flexible Annuloplasty Ring and Band are made of flexible, braided polyester, allowing them to mimic natural valve dynamics. The ring and band maintain their shape when used on or off the holder, enabling manipulation in varied approaches and exposures.

The Simulus flexible ring and band feature:

  • Flexibility without elasticity – discourages stretching, crimping, and bunching1
  • Low resistance – provides easy needle passage along the entire width of the ring
  • Tungsten and barium sulfate core – provides radiographic visualization
  • Trigone markers – assist in suture placement and ring/band positioning
  • Nine sizes – ranging from 23 mm to 39 mm

A spoke-ring holder used during implant is made of clear polysulfone for visibility. It features a proprietary one-cut release and a malleable handle to help reach the valve annulus.
