Designed to support the annulus and maintain the repair, the Simulus® Semi-Rigid Ring and Band accommodate annular flexion and leaflet curvature.
Surgeons can choose between a semi-rigid ring with a flexible anterior segment or a semi-rigid band, based on their preference and their patient’s needs.
The Simulus Semi-Rigid Annuloplasty Ring for mitral valve repair is a unique hybrid between a saddle shape and a flat ring. Conforming to the physiologic movement of the human mitral annuli, the Simulus Semi-Rigid Ring rises as a saddle in systole and flattens to a planar shape in diastole. Studies of rings that respect the dynamic curvature of the annulus indicate that they reduce valvular stress, potentially increasing repair durability.1,2 According to Jensen et al., “Saddle-shaped annuloplasty rings provide superior uniform annular force distribution compared to flat rings and appear to represent a configuration that minimizes out-of-plane forces that could potentially be transmitted to leaflets and chords.”2
The Simulus Semi-Rigid Annuloplasty Band provides support for posterior annuloplasty while preserving the physiologic motion of the aorto-mitral curtain. Constructed with an MP35N wire stiffener, the semi-rigid band helps stabilize the annulus. Flexible tips allow secure attachment at the trigones.
The Simulus Semi-Rigid Ring and Band include the following features:
Only physicians who have received proper training in valve repair should use this device.
Adverse events can include: thromboembolic events, dehiscence, hemolysis, stenosis, residual incompetence, heart block, endocarditis, systolic anterior motion, left ventricular outflow tract obstruction, anticoagulant-related bleeding or hemorrhage.
