294-3087-CA INFLATABLE TOOL WITH RIB EXPANSION SUPPORT An apparatus, such as a packer or bridge plug, and method of use, are provided for introduction into a subterranean well on a conduit. The apparatus has a cylindrical housing which may have upper and lower collars. An elastomeric seal is disposed around the exterior of the housing with a series of longitudinally extending ribs radially positioned around the housing. The ribs are outwardly and flexibly movable from retracted to expanded positions to anchor the apparatus in the well thereby resisting at least one of longitudinal and rotational movements. At least one elastically expandable belt is carried around the exterior, of the ribs. When the sealing element, which includes a tubular elastic body, is moved for sealing engagement within the well by application of fluid, the belt expands and radially conforms the flexing movement of the ribs.
