1. A delivery system for delivering a stent to a body lumen, the system comprising:
an outer tubular member defining a lumen and having a proximal end region and a distal end region;
a cutting element coupled to an inner surface of the outer tubular member adjacent to the distal end region thereof, the cutting element extending radially inward from the inner surface;
an inner tubular member defining a lumen and having a proximal end region and a distal end region, the inner tubular member slidably disposed within the lumen of the outer tubular member;
an expandable stent disposed about an outer surface of the inner tubular member adjacent the distal end region of the inner tubular member; and
a sheath releasably disposed over the expandable stent and configured to maintain the expandable stent in a radially collapsed configuration, the sheath having a proximal end and a distal end;
wherein the cutting element is configured to cut an entire length of the sheath, from the proximal end of the sheath to the distal end of the sheath, upon proximal retraction of the outer tubular member while remaining radially spaced from the expandable stent.
