Described is a barrier application device comprising a handle, an introducer assembly slidably and rotatably coupled to the handle, a beam assembly coupled to a distal end of the handle, and a flag coupled to the beam assembly. A method of using a barrier application device comprises providing a device comprising a handle, an introducer assembly slidably and rotatably coupled to the handle, a beam assembly coupled to a distal end of the handle, and a flag coupled to the beam assembly, and placing a barrier on the flag, sliding the introducer assembly along the handle from a retracted position to an extended position at least partially covering the beam assembly, and rotating the handle relative to the introducer assembly until the flag and the barrier are wound around the beam assembly.
