Unique Range of Sizes
Large sizes are preferred by surgeons in facilitating repair in the presence of severe degenerative MR like Barlow's disease or big annuli.
A complete range of sizes to meet a size-specific repair principle. The 42 mm size is unique to MEMO 4D.
Progressive Increase of the Anteroposterior Diameter
The progressive increase of the anteroposterior diameter of MEMO 4D, from size 34 to size 42, helps accommodate excess leaflet tissue while reducing the risk of Systolic Anterior Motion (SAM).
Exclusive Gradual Saddle Shaping
The anterior saddle shape, gradually enhanced from size 34 to size 42, is designed to optimize the physiological geometry in enlarged annuli that have lost their three-dimensional profile.
Stability and Support
The right balance of rigidity and flexibility to support any repair MEMO 4D, semi-rigid annuloplasty ring, provides the stability and support to the annulus while providing dynamic flexibility of movement.
The natural annular dynamics of the MEMO platform is clinically proven and acknowledged: “MEMO 3D preserves annular dynamics and folding dynamics.1”
“MEMO 3D allows for contraction during systole, an increased depth of coaptation of the leaflets, and an improvement in annular orifice area during diastole.4”
Three Layer Structure
- Oval silicone sheath: Ease-of-implant with a perfect annular fit
- Nitinol cell structure: Optimally accommodates the diastolic phase and provides consistent recovery of the natural systolic profile
- Carbofilm® Coating: Reduces inflammatory reaction favoring a gentle endothelialization.6,10
Truly physiological three-dimensional motion of the mitral annulus with a natural anterior/posterior to lateral/ lateral relationship to maximize blood flow,1,2,3,4,5 even five years after implantation.6
“In our study, the semi-rigid MEMO 3D annuloplasty ring was associated with a better hemodynamic at rest and during exercise and clinical status.3”
