Comprising a wire mesh structure covered with biocompatible material and, more particularly, a substantially cylindrical expandable endoprosthesis ( 10 ) covered with biosynthetic cellulosic membrane for the treatment of arterial stenosis, where such structure is introduced in a mold ( 11 ), which is made of a material that is impermeable to liquids and permeable to gases, together with a culture medium ( 12 ) inoculated with a cellulose-producing microorganism such as the Acetobacter xylinum, resulting in the formation of a cellulosic membrane juxtaposed to the inner wall of said mold. The membrane can be impregnated to the inner wall of said mold ( 11 ). The membrane can be impregnated with therapeutic agents to be locally released during a period of days or weeks. Methods used to mount and deploy the endoprosthesis in the body. |
