1. An access device for an endoscopic procedure, wherein said access device comprises:
(a) a tubular member comprising a proximal end region, a distal end region, an inflation chamber, an inner surface defining an inner diameter of said tubular member, and an outer surface defining an outer diameter of said tubular member, wherein said tubular member defines a lumen that extends from said proximal end region to said distal end region and is defined by said inner surface of said tubular member, and (b) an inflation port configured to allow gas to be introduced into said inflation chamber, thereby inflating said access device, wherein said outer diameter of said tubular member increases as said inflation chamber is inflated.
