"Equipment for use in a bore of the well, method for establishing a section not structured of a hole of shaft in an underground formation, the method to facilitate the use of a hole shaft, method for sealing a part of a well bore tubular system to facilitate communication to Over a hole of shaft and method of routing a line of well. A device suitable for use in a bore of the well comprises a bistable expandable device. A device for example has a plurality of cells biestu00e1veis, formed as a tubular configuration. Each bistable cell comprises at least two elongated parts which are connected to one another at their ends.The device is stable in a first configuration and a second configuration.
