  • Patent number: 8216304
    Abstract: An annuloplasty ring holder includes an angled post for improved visibility and access by the surgeon. The post may be configured to be adjusted in angle and rotation. The ring holder can include a relatively open lower template, including relatively narrow extending radial arms with short, generally arcuate ring-retaining distal portions. The invention includes placements of suture holes and cutting wells which, in combination with improved suture routing, afford the user improved access to cutting the suture that is used to retain the annuloplasty ring to the holder. Another annuloplasty ring and ring holder combination disclosed includes a generally triangular-shaped ring and a generally T-shaped holder. The ring holder has a base portion forming the top of the T shape and engaging against a first segment of the ring, with a radial arm extending from the base portion and forming the post of the T. The radial arm engages against a junction between two segments of the ring.
