ABSTRACT:
The invention relates to a vascular prosthesis wherein, fragments of biological tissues such as vascular tissues, connective tissues, fat tissues and muscular tissues and/or cells composing vascular walls such as vascular endothelial cells, smooth muscle cells and fibroblast cells are deposited and captured within the wall of a vascular prosthesis substrate; a manufacturing method comprising the steps of immersing a vascular prosthesis substrate into a dispersed solution of fragments of biological tissues such as vascular tissues, connective tissues, fat tissues and muscular tissues and/or cells composing vascular walls such as vascular endothelial cells, smooth muscle cells and fibroblast cells, and depositing and capturing the cells and/or tissue fragments on the inner wall and within the wall of the vascular prosthesis from one side to the other side of the vascular prosthesis substrate wall by providing a pressure differential between the outside and the inside of the vascular prosthesis substrate; and a substrate suitable for manufacturing a vascular prosthesis having a porous membrane having pores capable of trapping tissue fragments, or a laminate structure with such a membrane and another porous membrane having pores not large enough to pass the cells or tissue fragments.
