Abstract: Disclosed is a delivery device, kit, system, method, etc. for localized fusion of leaflets of a tissue valve, for example, a native heart valve, using an adhesive. The delivery device can have one or more capture features for capturing separate leaflets, for example, the anterior and posterior mitral leaflets. An applicator can be configured to apply a biocompatible adhesive between the captured leaflets, and one or more curing elements can be configured to cure the applied biocompatible adhesive. The kit can have the aforementioned delivery device, and the biocompatible adhesive used therewith. The method can include positioning the aforementioned delivery device adjacent the anterior and posterior mitral leaflets, capturing the mitral leaflets between the paddles of the delivery device, applying a biocompatible adhesive between the captured mitral leaflets via the applicator, and curing the applied biocompatible adhesive via the energy elements to locally fuse the mitral leaflets.
