Publication number: 20110040282Abstract: A tube that can be stiffened in a controlled manner has a pressure channel for controllable production of a stiffening overpressure by introduction of a pressure medium. The tube has several flexible stiffening elements, of which at least one is stable with respect to tensile force and which are pressed onto one another when acted upon by the stiffening overpressure with the result that the tube is changed from a more flexible state to a more flexurally stiff state. A channel is separate from the pressure channel and, in the stiffened state of the tube, forms a working channel whose course corresponds to the tube shape.Type: ApplicationFiled: February 14, 2007Publication date: February 17, 2011Applicant: EPFLEX FEINWERKTECHNIK GMBHInventor: Bernhard Uihlein
