Abstract
A stent composed by a bioabsorbable network of polymer fibers that can be rearranged upon expansion, accommodating for diameter enlargement without the need of a strut or strut pattern and providing temporary support to a biological duct, is provided. Additionally, a stent is provided where the rearranged fibrous network of its expanded state can act as a scaffold for cell infiltration and promote autologous tissue formation.
Claims19
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.
