An inflatable packer and a method for its use are provided for introduction into a subterranean well bore on a conduit. A fold can form in the inflatable elastomeric bladder of the packer during inflation or deflation, forming a seal on the central body or mandrel which obstructs the effective passage of fluid, thereby obstructing inflation and deflation of the bladder. The packer provides a fluid path to effectively communicate pressured fluid along the entire interior length of the bladder, thus effectively tolerating the fold and any otherwise fluid-obstructing seal.
