1. produce interim hemostatic method in certain position in mammiferous tissue, said method comprising the steps of:

  • A) the interim thromboembolism solution that will comprise reverse thermally sensitive polymeric is incorporated in the vascular system of described tissue in certain position of leading to described position by circulation, the composition of wherein said thromboembolism solution and concentration can make it gelling fully take place effectively to stop the blood flow at described position under gelation temperature Tg, and described temperature T g is higher than the local organization temperature of the tissue of being treated;

    B) pour into described position with described reverse thermally sensitized polymerization compositions;

    WithC) before described perfusion or in the filling process, heat the described position temperature of Tg extremely at least;

    Thereby produce interim hemostasis at described mammiferous described position.
