Abstract: An inflation diffuser including a non-rigid first section having a passageway for the passage of lift gas passing through a fill port positioned on a balloon envelope, a porous and non-rigid second section attached to the non-rigid first section, wherein the porous and non-rigid second section is comprised of a mesh material, wherein the non-rigid first section is less porous than the porous and non-rigid second section, and wherein the porous and non-rigid second section is not in contact with the balloon envelope at the end of an inflation process to direct lift gas towards the center of, and away from, the balloon envelope.
