A first cutting element extending from the distal end of the elongated shaft so as to contact tissue. A second cutting element disposed in the passageway and extending from the distal end of the elongated shaft and configured for retractable extension beyond the distal end of the elongated shaft so as to contact tissue. A deployment mechanism disposed with the proximal end of the elongated shaft and configured to engage the second cutting element.
