Abstract: A surgical instrument implementing a leaflet grabbing mechanism by a leaflet grabbing structure is provided, in which the leaflet can be grabbed and clamped between a first and a second abutment surface. The first, proximally facing abutment surface in this belongs to a swivel-out portion of the leaflet grabbing structure. More in particular, swivel-out portion comprises at least a first arm (111) and a second arm (112). In a released state, when the leaflet grabbing structure is released from a catheter, the arms are capable of swiveling: the first arm is capable of swiveling out with respect to a main body (101) to which it is attached, and the second arm is capable of swiveling relative to the first arm so that in a leaflet grabbing position the first abutment surface faces proximally. The second arm comprises 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. The second abutment surface may be constituted by a press pad formed by a distal end face of the counterportion (80) that is releasable from the catheter and axially movable relative to the main body.
