The Memo 3D ReChord annuloplasty ring designed by Sorin Group
for mitral valve repair procedures has received FDA clearance. This device that
is semi-rigid in nature, is an upgrade to the existing Memo 3D ring, now
featuring a new chordal guidance system that helps with implantation,
particularly in the case of performing artificial Gore-Tex chordae replacement.
Sorin's unique Carbofilm coating covers the ring, which according to the company, improves the hemo-compatibility of the ring and its flexible shape, as the "3D" in the name implies, while staying put within the annulus, allows it to bend along with the heart's motion.
According to its product page, the following details about the Memo 3D ReChord have been said:
- 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 Sorin's innovative Perceval sutureless aortic prosthesis
- 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
- Truly physiological three-dimensional motion of the mitral annulus with a natural anterior/posterior to lateral/lateral relationship to maximize blood flow, even after more than five years from implantation
- 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
