摘要：
a connection device for the valve leaflet includes: a base； and first and second followers that extend from the base. a 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 the first arm, to capture a first leaflet between them. a 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 the second arm, to capture a second leaflet between them. the first and second followers are resiliently deformable between: (i) an open condition, in which: the point from which the first arm extends from the first follower； and the point from which the second arm extends from the second follower, are spaced more than 15 mm； and (ii) a closed condition, in which: the point from which the first arm extends from the first follower； and the point from which the second arm extends from the second follower, are spaced less than 5 mm. the deformation medium deforms the followers towards the closed condition. a positioner extending from the base, between the first and second followers, and a fixer that is releasably held to the positioner, includes the first and second fixation jaws. the first and second jaws: extend away from the base； and are movable between: (i) an expanded condition, in which leaflets can be received between the first and second clamping jaws； and (ii) an insured condition, in which the first and second clamping jaws hold the leaflets between them. in use: (i) the first and second followers can be: passed axially through a valve, between the first and second leaflets of the valve； and deformed resiliently by opening and closing the valve leaflets； (ii) the first arm can capture the first leaflet between the first arm and the first follower, and the second arm can capture the second leaflet between the second arm and the second follower, with the f
