Shape memory annuloplasty ring and holder
First Claim
1. An annuloplasty ring, comprising:
- an elastomeric member;
a shape memory member disposed in the elastomeric member enabling the annuloplasty ring to exhibit a compressed form and an expanded post implant form that is suitable for providing a desired flexibility in the annuloplasty ring after implantation depending on the temperature of the shape memory member; and
an outer wrap covering the elastomeric member.

Abstract
An annuloplasty ring includes an elastomeric member, a shape memory member, and an outer wrap covering the elastomeric member. The shape memory member is disposed in the elastomeric member and enables the annuloplasty ring to exhibit a compressed form and an expanded form depending on the temperature of the shape memory member. A method of training an annuloplasty ring includes bringing a shape memory member of the annuloplasty ring to a temperature above its transformation temperature range and plastically deforming the shape memory member into its expanded shape. The method further includes bringing the shape memory member to a temperature below its transformation temperature range and plastically deforming the shape memory member into its compressed shape.
