Memo 4D^™

Design

• Range of sizes. Up to 42 mm to treat large annuli. The 42 mm size is unique to Memo 4D among semi-rigid annuloplasty rings.
• Progressive anteroposterior diameter. Increases from size 34 to size 42 to accommodate excess leaflet tissue, while reducing the risk of systolic anterior motion (SAM).
• Gradual saddle shaping. The anterior saddle shape is gradually enhanced from size 34 to size 42, to restore physiological geometry in enlarged annuli that have lost their three-dimensional profile.
• Stability and support. A balance of rigidity and flexibility that covers a comprehensive range of mitral valve repair needs.

Three-layer structure

• Oval silicone sheath. Ease of implant with an adequate annular fit.
• Nitinol cell structure. Accommodates the diastolic phase and provides consistent recovery of the natural systolic profile.
• Carbofilm coating. Reduces inflammatory reaction, favouring gentle endothelialisation.

Ease of implant

• Slim-fit ring. A wide, streamlined silicone filler facilitates suturability, and the ring is designed to fit the mitral annulus.
• Versatile holder. A chordal window lets neochordae pass through the aperture, and a single cut unhooks the whole holder.
• Designed for MICS. A low-profile holder and an ultra-slim template with two handles.

ReChord system

A chordal sizing system that aims to standardise neochordae implantation without the need for physical measurement. A series of loops in the posterior region act as temporary reference elements for sizing chord length, for both anterior and posterior repair. The result is a reproducible technique and shorter procedure times.
