Expandable implantable conduit

An implantable device comprising:

• a plastically deformable conduit comprising a continuous sheet of a biocompatible polymer, the plastically deformable conduit having an outer surface having a length;
• and
• wherein the plastically deformable conduit has a plurality of dashed radiopaque circumferential markings spaced along the length of the outer surface;
• wherein the plastically deformable conduit has a plurality of dashed radiopaque longitudinal markings spaced along the length of the outer surface;
• wherein the plastically deformable conduit is configured to be expanded from a pre-expansion state having a pre-expansion inner diameter to a post-expansion state having a post-expansion inner diameter;
• wherein the plastically deformable conduit has a yield strength of about 0.1 MPa to about 4 MPa;
• and
• wherein the plastically deformable conduit has an internode distance of about 10 μm to about 40 μm.
