Abstract
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.
