Title:
STENT GRAFT, ARTIFICIAL BLOOD VESSEL, BIOLOGICAL IMPLANT MATERIAL, COMPOUND THREAD, AND METHOD FOR MANUFACTURING A COMPOUND THREAD AND BIOLOGICAL IMPLANT MATERIAL
Document Type and Number:
WIPO Patent Application WO/2010/137301
Kind Code:
A1
Abstract:
Provided is a compound thread (12) wherein: a core part (13) comprises a multifilament including a non-biodegradable synthetic high-molecular filament; a sheath part (14) comprises a multifilament including a bioabsorbable polymer filament which is intertwined with the non-biodegradable synthetic high-molecular filament and is formed so as to surround the core part (13); and the sheath part (14) is porous due to the bioabsorbable polymer filament. When the provided compound thread is implanted in a living body as a part of blood vessels, thrombus formation is inhibited and cell tissue between the compound thread and blood vessels can be produced efficiently.
