LivaNova Memo 3D annuloplasty ring has been engineered with the aim to create a unique and optimal solution across the entire spectrum of mitral valve repair. The unique core of Memo 3D provides a firm support to the mitral annulus while allowing the natural physiological 3D motion that truly reflects the native mitral annulus. The innovative design of Memo 3D provides reproducible results, predictable outcomes, and superior performance combined with enhanced hemo and biocompatibility.

Unique super-elastic alloy core

The exclusive alloy core cell design is a laser-cut one-piece structure that allows truly physiological annular dynamics. The precision laser-cutting technology is also used to obtain LivaNova’s innovative Perceval sutureless aortic prosthesis.

Shape Memory

The superelastic alloy core “remembers” a prefixed shape after geometric deformation and can be flexed back and forth without losing its original form. Memo 3D’s shape memory provides consistent recovery of the systolic profile and restores the natural systolic diameter ratio.

The Right Balance of Rigidity and Flexibility to Support any Repair

Memo 3D, semi-rigid annuloplasty ring, is truly the only ring you’ll ever need whether you’re looking for stability to support the annulus or flexibility of movement. The innovative superelastic alloy cell structure is optimized to provide a progressive degree of flexibility from the anterior to posterior portions of the ring to allow physiological, three-dimensional motion to accommodate native mitral annulus dynamics and to reduce stress on the repair.

Three layer structure

Ease of implant with superior visualization, placement and attachment while ensuring a perfect annular fit. The oval silicone sheath provides easy suturability with conformable needle penetration.

CarbofilmTM coating

The bio/hemocompatible properties of the unique CarbofilmTM coating allows complete endothelialization, prevents inflammatory reaction and scar tissue formation. Designed to maintain physiological dynamics in the long term.
