Abstract

A cutting device includes an elongated shaft extending between a proximal end and a distal end. A lower portion extends from the distal end of the elongated shaft and includes an outer surface and an inner surface spaced apart from the outer surface which together form a blunt end configured as a stop so as to protect adjacent tissue. An upper portion extends from the distal end of the elongated shaft and including an inner surface. The upper portion is configured so as to be disposed opposite the lower portion. A cutting element is disposed between the lower portion and the upper portion and is configured for retractable extension beyond the distal end of the elongated shaft so as to contact tissue.
