Abstract
An inflatable packer element utilizing metal cable employed to reinforce the elastomeric packer bladder as an anchoring element. Steel cable is exposed along at least a portion of the packer element surface to engage a casing, liner or other conduit wall, or the wall of an open well bore. A seal may be effected at one or both ends of the packer element through use of a bonded elastomer cover which is pressed against the conduit wall by the expanded cable when the packer element is inflated.
