Abstract
Provided is a medical base material that is suitable for regeneration of a cardiovascular system being exposed to high pressure from a lumen, such as an aorta and is absorbed by a living body after transplantation. The medical base material of the present invention has a sheet shape, a tube shape, or a combined shape thereof and is used for regeneration of a cardiovascular system by being transplanted in a body. The medical base material has a multilayer structure at least including an inner layer to be arranged on the intimal side of the cardiovascular system and an outer layer to be arranged on the adventitial side of the cardiovascular system from the inner layer and made from a material at least including a stereo complex polylactic acid. The layer to be arranged on the adventitial side of the cardiovascular system from the inner layer is formed in a porous form such that a nutrient blood vessel reaches the inner layer or enters the vicinity of the inner layer.
