    摘要： Medical Implant (100), comprising - a microbial cellulose tube (1), comprising a wall (2) having an inner surface (3) and an outer surface (4), wherein the wall comprises several layers (5, 6, 7) of microbial cellulose, wherein said layers are concentric or substantially concentric to a longitudinal axis (L) of the tube, - a stent (9) which placed inside of the microbial cellulose tube (1), wherein an outer surface (10) of the stent contacts the inner surface (3) of the microbial cellulose tube (1), and method for producing such implant. The implant can be covered with newly created bile duct epithelium, thereby creating a new bile duct from body cells. The implant can be removed after completion of creation of the new bile duct. So, the implant as suitable as a temporary implant. The implant can be used for surgery, such as surgery of gall bladder, bile duct and/or liver, e.g. gall bladder removal, hepatobiliary malignancy surgery or liver transplantation. The implant can particularly be used for repairing or regeneration of bile duct. Further fields of use are the use as esophagus implant or urether implant.
