The present invention provides apparatus and a method of anchoring an expandable conduit. A formation is provided on an outer surface of the conduit, the formation comprising a number of bands of a friction and/or sealing material. When the expandable conduit is radially expanded, the friction and/or sealing material engages a second conduit in which the expandable conduit is located. The engagement of the friction and/or sealing material provides an anchor for the expandable conduit.

L'invention porte sur un appareil et un procédé de blocage d'un conduit dilatable. A cet effet, on pose sur l'une des surfaces extérieures du conduit une formation composée de plusieurs bandes d'un matériau de friction et/ou d'étanchéité. Lorsqu'on procède à la dilatation radiale du conduit, le matériau de friction et/ou d'étanchéité entre en contact avec un deuxième conduit entourant le conduit dilatable. Ledit matériau constitue alors un élément de blocage du conduit dilatable.
