    • The present invention provides fluid and material delivery methods and devices for practicing the methods. The invention provides a method of delivering cellular material comprising injecting the cellular material into a subject such that the injected cells retain their inherent morphologic characteristics upon injection. The method comprises the steps of aspirating the cellular material into a fluid delivery device which incorporates a syringe arrangement. The cellular material is aspirated into the main body of the syringe until the desired amount of a material has filled the syringe body. The needle of the fluid delivery device is then inserted into the skin of a subject at an angle about parallel to the skin until a desired depth has been reached. The cellular material is then injected in the subject until the desired volume of material has been injected. The needle of the device is then rotated approximately 45 to 90 degrees and the needle is removed from the injection site.
    • 本发明提供了用于实施该方法的流体和材料输送方法和装置。 本发明提供了递送细胞材料的方法,包括将细胞材料注射到受试者中,使得注射的细胞在注射时保持其固有的形态特征。 该方法包括将多孔材料吸入包含注射器装置的流体递送装置中的步骤。 将细胞材料吸入注射器的主体中,直到所需量的材料填充注射器体。 然后将流体输送装置的针以与皮肤平行的角度插入受试者的皮肤中,直到达到所需的深度。 然后将细胞材料注射到受试者中,直到注入了所需体积的材料。 然后将装置的针旋转约45度至90度,并将针从注射部位移除。
