A device and method for enlarging and supporting a body cavity are disclosed. One embodiment of the device comprises a tubular, distending balloon having first and second distending members, spaced apart from one another, wherein the distending members are inflatable. A tubular connector interconnects the first and second distending members and forms a conduit which allows for unimpeded passage of objects through the balloon. The balloon is adapted to be inserted into a body cavity in a deflated or semi-deflated state. When the distending members are inflated, an outer surface of the balloon exerts pressure on an interior surface of the body cavity, thereby supporting the body cavity in a distended state while allowing for unimpeded passage of medical instrument and biological material through the balloon.
