摘要
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.
