1. An apparatus for injecting material into organic tissue through a layer of skin, the apparatus comprising;
a reservoir for holding a quantity of the material,
a cannula with at least one outlet adjacent to a free end of the cannula and through which the material from the reservoir is injected into the organic tissue,
a plunger situated within the reservoir, and
a skin surface sensing means situated about the cannula and mechanically coupled to the plunger;
and the apparatus is configured to distribute the material into the organic tissue between;
a first depth in the organic tissue from the surface of the skin, and
a second depth in the organic tissue from the surface of the skin;
wherein a first end of the skin surface sensing means is configured to contact the surface of the skin after the free end of the cannula is inserted through the surface of the skin and reaches the first depth, and a second end of the skin surface sensing means is configured to retract within the reservoir and cause the plunger to move the free end of the cannula from the first depth to the second depth and push the material out of the reservoir and through the at least one outlet of the cannula;
wherein the apparatus comprises a valve which is configured to refill the reservoir of the apparatus from a material supply connected to the apparatus when the apparatus is in use.
