[ What is claimed:] [1.] A device for subcutaneously depositing a solid material, the device comprising:a) a housing;b) a trocar having a sharpened distal end, a proximal end and a length sufficient to subcutaneously deposit the solid material, the trocar being secured via its proximal end to the housing;c) a tubular channel running coaxially through the housing and the trocar, the tubular channel having internal dimensions to accommodate the storage and passage of the solid material;d) an obturator having a length and dimensions to pass through the tubular channel through the housing and trocar to facilitate passage of the solid material therethrough;e) one or more grooves in or associated with the length of the obturator;f) one or more biased members coupled to the housing, with each biased member having a biased arm and a protrusion, the biased arm reversibly extending the protrusion into the tubular channel to interact with the one or more grooves in or associated with the length of the obturator to facilitate a uni-directional movement of the obturator through the tubular channel; andg) a tissue penetration guide, the penetration guide extending a length from the housing as a linear extension of material maintained parallel to and separated by a distance from the trocar, the length of the trocar, length of the penetration guide and the distance between the trocar and the penetration guide being sufficient to:i) allow the tissue to pass between the trocar and the penetration guide; andii) allow the trocar to be fully inserted into or under the tissue; andiii) to limit the angle and depth of insertion of the trocar into or under the tissue.
