Abstract
Adjacent tissue layers can be accessed using a catheter device with a distal tip having a conductive portion including a first cutting feature and one or more projections extending from the first cutting feature towards an outer diameter of the distal tip. Electrical energy can be supplied to the conductive portion of the device to cut tissue. A stent can be delivered to form a fluid communication between the adjacent tissue layers.
