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.
Claims9
A stent for implantation into a biological duct, comprising:
- an expandable tubular conduit made out of a bio-absorbable fibrous network,
- wherein the fibrous network distinguishes:
- (i) a first state with a first diameter of the tubular conduit determined by a first fiber orientation characterized by a first fiber dispersion and a first main angle difference, and a first average fiber diameter, and
- (ii) a second state with a second diameter of the tubular conduit determined by a second fiber orientation characterized by a second fiber dispersion and a second main angle difference, and a second average fiber diameter,
- wherein the first diameter of the tubular conduit is smaller than the second diameter of the tubular conduit,
- wherein the transition from the first state to the second state is accommodated only by rearrangement of the fibers in the fibrous network and does not rely on a strut pattern,
- wherein the fibrous network in the second state provides mechanical support to the biological duct, and
- wherein the fibrous network in the second state allows for cell infiltration and may act as a scaffold to induce autologous tissue formation.
