A valve leaflet connecting device including: a base that defines a longitudinal axis (A-A); first and second followers extending from the base; a first arm on the first follower, which first arm extends from the first follower in a direction away from the second follower and away from the base to define an acute angle between the first follower and first arm for capturing a first leaflet there between; a second arm on the second follower, which second arm extends from the second follower in a direction away from the first follower and away from the base to define an acute angle between the second follower and second arm for capturing a second leaflet there between; characterised in that the first and second followers are resiliently deformable between: an open condition, in which: a first virtual line (B-B) that: intersects the point from which the first arm extends from the first follower; and runs parallel to the longitudinal axis of the base; and a second virtual line (C-C) that: intersects the point from which the second arm extends from the second follower; and runs parallel to the longitudinal axis of the base, are spaced more than 15mm; and a closed condition, in which the first and second virtual lines are spaced less than 5mm; and deforming means for deforming the followers towards the closed condition, such that, in use: (i) the first and second followers may be: passed axially through a valve, between first and second valve leaflets; and resiliently deformed by opening and closing of the valve leaflets; (ii) the first arm may capture the first leaflet between the first arm and the first follower, and the second arm may capture the second leaflet between the second arm and the second follower, with the first and second followers disposed between the first and second leaflets; and (iii) the deforming means may deform the first and second followers towards the closed condition, thereby moving the first and second leaflets towards each other. a base that defines a longitudinal axis (A-A); first and second followers extending from the base; a first arm on the first follower, which first arm extends from the first follower in a direction away from the second follower and away from the base to define an acute angle between the first follower and first arm for capturing a first leaflet there between; a second arm on the second follower, which second arm extends from the second follower in a direction away from the first follower and away from the base to define an acute angle between the second follower and second arm for capturing a second leaflet there between; characterised in that the first and second followers are resiliently deformable between: an open condition, in which: a first virtual line (B-B) that: intersects the point from which the first arm extends from the first follower; and runs parallel to the longitudinal axis of the base; and a second virtual line (C-C) that: intersects the point from which the second arm extends from the second follower; and runs parallel to the longitudinal axis of the base, are spaced more than 15mm; and a closed condition, in which the first and second virtual lines are spaced less than 5mm; and an open condition, in which: a first virtual line (B-B) that: intersects the point from which the first arm extends from the first follower; and runs parallel to the longitudinal axis of the base; and a second virtual line (C-C) that: intersects the point from which the second arm extends from the second follower; and runs parallel to the longitudinal axis of the base, a first virtual line (B-B) that: intersects the point from which the first arm extends from the first follower; and runs parallel to the longitudinal axis of the base; and a second virtual line (C-C) that: intersects the point from which the second arm extends from the second follower; and runs parallel to the longitudinal axis of the base, are spaced more than 15mm; and a closed condition, in which the first and second virtual lines are spaced less than 5mm; and deforming means for deforming the followers towards the closed condition, such that, in use: (i) the first and second followers may be: passed axially through a valve, between first and second valve leaflets; and resiliently deformed by opening and closing of the valve leaflets; (ii) the first arm may capture the first leaflet between the first arm and the first follower, and the second arm may capture the second leaflet between the second arm and the second follower, with the first and second followers disposed between the first and second leaflets; and (iii) the deforming means may deform the first and second followers towards the closed condition, thereby moving the first and second leaflets towards each other. (i) the first and second followers may be: passed axially through a valve, between first and second valve leaflets; and resiliently deformed by opening and closing of the valve leaflets; (ii) the first arm may capture the first leaflet between the first arm and the first follower, and the second arm may capture the second leaflet between the second arm and the second follower, with the first and second followers disposed between the first and second leaflets; and (iii) the deforming means may deform the first and second followers towards the closed condition, thereby moving the first and second leaflets towards each other.
