Abstract
A hose is described that includes a braided matrix with an interior lumen. The matrix also includes filaments that intersect one another, 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 by 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.
