Disclosed herein are devices and systems adapted to position within a subject and methods of use therewith. The device includes a conduit body having at least a first layer and a second opposable layer manufactured from a biocompatible and malleable material that permits safe positioning within the subject. The device also includes an enclosed intervening cavity positioned between the first and second layers, the first surface of the first layer having at least one feature configured to interlock with the second surface of the second layer. The conduit body is configured to transition from a first state to a second state upon application of a suction force to the intervening cavity wherein the conduit body is less rigid in the first state than when the conduit body is in the second state, and wherein the conduit body is adapted to remain in the second state after removal of the suction force.
