Abstract: A medical system for creating a communication channel between two anatomical structures includes an outer member having a proximal portion and a distal portion, and a lumen extending from the proximal portion to the distal portion. At least a portion of the lumen includes an electrically conductive surface extending to a distal end of the distal portion. The system includes an inner member having a proximal portion and a distal portion. The inner member is configured to translate within the lumen and to deliver a therapy to target tissue. The inner member distal portion includes a conductive distal tip configured to electrically couple with the electrically conductive surface of the outer member. The inner member includes a proximal portion adapted to electrically couple the conductive distal tip to an auxiliary device.

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.
