Abstract: The present invention relates to a device capable of wrapping the outer wall of a blood vessel, and a method for manufacturing the device. If the device for wrapping the outer wall of a blood vessel of the present invention is used, the outer wall of a blood vessel is wrapped, and, thereby, vortex generation can be significantly decreased by controlling abnormal expansion of the blood vessel which can occur due to the difference in the characteristics of blood vessels in a vein-artery graft model. The present invention saves a blood vessel from a low-oxygen state by promoting generation of new blood vessels on the outer wall of the blood vessel via a regenerative inflammatory response caused by the material of the device, and provides synergy effects such as prevention of vascular stenosis and reinforcement of an outer muscular layer by guiding venous muscular cells to the outside.
