1. A graft, comprising: an expandable construct made out of a fibrous network,
wherein the fibrous network distinguishes:
(i) a first state with a first geometrical dimension of the construct determined by a first fiber orientation characterized by a first fiber dispersion and a first main angle difference, and a first average fiber geometrical dimension, and
(ii) a second state with a second geometrical dimension of the construct determined by a second fiber orientation characterized by a second fiber dispersion and a second main angle difference, and a second average fiber geometrical dimension,
characterized in that the transition from the first state to the second state is accommodated only by rearrangement of the fibers in the fibrous network, with the proviso that the transition does not rely on a strut pattern.
