ABSTRACT:
An improved device for subcutaneous implantation of single and plural elongated medicament pellets comprising a single dosage where magazine feeding is not applicable because considerations of sterility and cross-contamination require a fresh needle and obturator for each patient. The device includes a cannula supported at a proximal end thereof by a hub which slides within a tubular barrel, the barrel supporting an obturator which selectively penetrates the cannula to maintain an implanted pellet in position as the cannula is withdrawn. For single pellet dosages, the pellet is carried in the fore part of the cannula, while in the case of multiple pellet dosages, the additional pellets, prior to loading, are carried in open-ended cylindrical tubes engageable with a proximal end of the hub whereby the obturator may be employed to transfer the pellet to the cannula from the sleeve which is discarded. Repositioning of the hub within the sleeve is then accomplished without disengagement of the distal end of the cannula from the tissues of the patient and additional implantations may then be performed.
