A medical device includes an elongate shaft with an inflatable balloon at its distal region. The balloon has an outer surface and can switch between deflated and inflated configurations. An electrocautery electrode is located on the balloon's outer surface. A shield member extends along the valve leaflet opposite to the balloon, such that the leaflet sits between them. The shield member can conform to the deflated balloon and extend laterally when inflated. It protects surrounding anatomy and prevents electrical contact with previously implanted heart valve frameworks. The device includes alignment features to help position the balloon both translationally and rotationally relative to the valve leaflet. The shield member can be made of polymeric or metallic materials and can extend into adjacent valve cusps. This medical device is designed for safely and precisely lacerating valve leaflets while protecting surrounding tissues.
