An artificial blood vessel comprising a tube made of a supporting skeletal material and a collagen layer of ultrafine fibers provided at least outside the tube, and a process for preparing the same. This vessel is advantageous in that the material therefor is easily available, that the application to a living body causes no significant rejection, that a suture may be held after implantation for a long period of time, and that, after a given period of time, it can be entirely or partially absorbed into the living body and decomposed. |
