Abstract
To develop a new biomedical polymer, it was suggested that the most important point was how naturally to induce a function and ability of the living body by the polymer. The living body has a nature of adaptability and restoration ability. Many of the artificial organs have been accepted to the living body by the nature. For example, against several types of vascular prostheses and grafts, the living body accepted them, however, the living body had made efforts to accept themin its own way.
So that. if the living body falls into a poor condition, the limit of the adaptability of it becomes narrow, and the artificial organs resulted to be functional disordered So we have develop a new materials which do not forced the living body to accept it.
