A hose is described that includes a braided matrix with an interior lumen. The matrix also includes filaments that intersect each other creating a braid, a longitudinal axis that runs along the lumen and the filaments intersect the longitudinal axis at a braid angle. The braid angle can be varied by compressing or expanding the matrix along the direction of the longitudinal axis. A polymer coating is applied to the matrix such that the matrix is substantially impermeable to air. The hose has two states: (1) a relaxed state where the hose does not experience a force in the direction of the longitudinal axis; and (2) a stressed state where the hose experiences a force in the direction of the longitudinal axis. The braid angle is larger in the relaxed state as compared to the stressed state. A method of manufacture for the hose is also disclosed. L'invention concerne un tuyau qui comprend une matrice tressée avec une lumière intérieure. La matrice comprend également des filaments qui se croisent, créant une tresse, un axe longitudinal qui s'étend le long de la lumière et les filaments croisant l'axe longitudinal selon un angle de tressage. L'angle de tressage peut être modifié par compression ou expansion de la matrice le long de la direction de l'axe longitudinal. Un revêtement polymère est appliqué sur la matrice de telle sorte que la matrice est sensiblement imperméable à l'air. Le tuyau présente deux états : (1) un état relâché dans lequel le tuyau ne subit pas de force dans la direction de l'axe longitudinal ; et (2) un état contraint dans lequel le tuyau subit une force dans la direction de l'axe longitudinal. L'angle de tressage est plus grand dans l'état relâché par comparaison à l'état contraint. L'invention concerne également une méthode de fabrication du tuyau.
