Abstract:
A stent-graft comprising:a tubular annealed structure formed of a plurality of filaments, each filament comprising bioabsorbable material and having an average diameter in the range of about 0.15 mm to about 0.6 mm; wherein said filaments include a first set of the filaments wound helically about an axis of the tubular structure and having a first common direction of winding, and a second set of the filaments wound helically about the axis and having a second common direction of winding, whereby the filaments of the second set cross the filaments of the first set at an axially directed angle; and wherein the filaments have tensile strengths and tensile moduli whereby the tubular structure is radially compressible and radially self-expandable; and a compliant graft cooperating with at least a portion of the tubular structure to form a stent-graft adapted to be disposed in a body lumen.
