  • Patent number: 8496714
    Abstract: The present invention aims to provide a material for revascularization which enables the regeneration of a blood vessel at an extremely high efficiency by being transplanted into a defect of the blood vessel. The present invention provides a tubular material for revascularization comprising a foamed body comprising a bioabsorbable material, a reinforcing member comprising a bioabsorbable material for reinforcing the foamed body, and a reinforcing yarn comprising a bioabsorbable material for reinforcing the foamed body, wherein the reinforcing yarn and the reinforcing member are located at the center or outer face of the foamed body, the inner face thereof is the foamed body, the reinforcing yarn is wound around in a spiral-shaped, ring-shaped or X-shaped manner, and the reinforcing yarn comprises a glycolide-?-caprolactone copolymer.
