Abstract: A medical assembly includes a guide catheter with a lumen extending therethrough and an electrocautery member slidingly disposed within the lumen. The electrocautery member has an elongate shaft with a proximal shaft segment and a distal shaft segment adapted to be movable between a puncture position and a laceration position. In some cases, a hinge segment is disposed between the proximal shaft segment and the distal shaft segment and includes a leading edge adapted to form a puncture within a cardiac valve leaflet when the distal shaft segment is in its puncture position and a trailing edge adapted to lacerate the cardiac valve leaflet when the distal shaft segment is in its laceration position. In some cases, the electrocautery member includes electrically isolated puncture and lacerating electrodes.
