1. A medical device comprising:
an elongate body having a proximal portion, a distal portion, and defining a lumen therethrough;
an expandable element being coupled to the distal portion of the elongate body, the expandable element having an inner surface and an outer surface opposite the inner surface, the expandable element defining a proximal portion of the outer surface, a distal portion of the outer surface opposite the proximal portion of the outer surface and an intermediate portion of the outer surface disposed between the proximal portion of the outer surface and the distal portion of the outer surface; and
a plurality of cutting members, each cutting member being coupled with the outer surface of the expandable element, each cutting member having a proximal end and a distal end opposite the proximal end, the proximal end being proximate to the proximal portion of the outer surface and the distal end being proximate to the intermediate portion of the outer surface, the proximal portion of the outer surface having a first diameter, the distal portion of the outer surface having a second diameter, and the intermediate portion of the outer surface having a third diameter, the third diameter being larger than the first diameter and the second diameter.
