A trigonal-papillary sizing device (120) comprises a handle (122) attached to a two forked prong (127,128). The two forked prong has a proximal portion (123) and two distal ends each having an equivalent length. The proximal portion connects the two prongs and the two distal prong ends are rounded. The distance between the two prongs and the length of the two prongs are equal, this distance being equal to an intertrigonal distance (124). A packaged medical device comprises a cardiac prosthesis, an annuloplasty ring and instruction to position the prosthesis about papillary muscles. The cardiac prosthesis comprises a semi-circular band portion (90;96;115;118;200;204;212;214;220;224;230) having first and second ends, these ends each including portions of a tether which are secured to each other to provide an adjustable semi-circular band. |
