A device for treating tissue includes a catheter including an elongated body extending from a proximal end to a distal end and including a lumen extending therethrough, a distal tip connected to the distal end of the elongated body and including a first electrode and a second electrode extending thereabout, the first electrode extending to a distal opening of the lumen and a first needle extending longitudinally from a proximal end to a distal end, the first needle slidably received within the lumen of the catheter to be moved between a retracted bipolar configuration, in which the distal end of the needle is proximal the distal opening of the catheter, and an extended monopolar configuration, in which the distal end of the first needle extends distally past the distal opening of the catheter so that the first needle contacts the first electrode and is configured to cut tissue.
