Zusammenfassung:A surgical instrument implementing a leaflet grabbing mechanism by a leaflet grabbing structure, in which the leaflet can be grabbed and clamped between first and second abutment surfaces. The first, proximally facing abutment surface belongs to a swivel-out portion of the leaflet grabbing structure, which includes at least a first arm and a second arm. In a released state, when the leaflet grabbing structure is released from a catheter, the arms are capable of swiveling: the first arm may swivel with respect to a main body to which it is attached, and the second arm may swivel relative to the first arm so that in a leaflet grabbing position the first abutment surface faces proximally. The second arm includes a recess arranged so that a chord extending between a released distal implant part and a proximal implant part can extend therethrough and be released by a lateral relative movement.
