血管再生用移植材料
Document Type and Number:
Japanese Patent JP6473695
Kind Code:
B2
Abstract:
Provided is a graft material capable of securing a sufficient space for regenerated tissue in the implantation site, and thereby promoting the regeneration of a blood vessel. Specifically, the present invention provides a revascularization graft material including an outer tube and an inner tube each being formed by knitting twisted yarns of biodegradable single yarns into a hollow tubular structure, wherein there is provided, in the lumen of the outer tube, at least one inner tube having an outer diameter smaller than the lumen diameter of the outer tube. The inner tube functions as a core material for the outer tube, and accordingly the revascularization graft material is excellent in kinking resistance, and the occlusion of the lumen hardly occurs.
