The Carpentier-Edwards Classic Annuloplasty Ring was first introduced in 1968. The first implants were at the Hospital Broussais in Paris by Prof. Alain Carpentier. The ring was manufactured and distributed by the French company, Rhone-Poulenc. In 1980, Edwards Laboratories (now Edwards Lifesciences) took over manufacturing and distribution rights of the annuloplasty ring. Originally made from stainless steel, the core of the ring was changed to titanium in 1983. The reason for the change was the increased strength of the titanium metal over stainless steel and complexity of forming the stainless steel rings. The name “Classic” was introduced in 1995 to reinforce its history as the ring of choice for thousands of surgeons since 1968.
- The Carpentier-Edwards Classic Annuloplasty Ring is available in two designs: a kidney shaped mitral ring (Models 4400/4425) and an oval tricuspid ring (Models 4500/4525).
- The Carpentier-Edwards Classic Annuloplasty Rings are constructed of titanium alloy covered by a layer of silicone rubber. The ring is then covered with a polyester knit fabric
Carpentier-Edwards Physio Annuloplasty Ring
- The Carpentier-Edwards Physio Annuloplasty Ring (Models 4450/4475) is available for the mitral valve only.
The Carpentier-Edwards Physio Annuloplasty Ring is a saddle-shaped ring made of bands separated by polyester film strips and welded together along the top portion of the ring. This construction enables the ring to be more flexible in the lower segment and more rigid in the upper segment. The metal/polyester construction is covered by silicone rubber and a woven polyester cloth.

- The Cosgrove-Edwards Annuloplasty System (Models 4600/4625) may be used in either mitral or tricuspid repairs.
- The implantable reinforcement band is made of silicone covered by a polyester velour cloth.
