Abstract
Methods and apparatus are provided for loading therapeutic materials into brachytherapy needles. The apparatus comprises an apparatus with chambers, and radioactive seed and spacer cartridges received therein. The apparatus may be used in conjunction with a standard brachytherapy needle coupled to the distal end of the apparatus. The plunger dislodges seeds and spacers from the cartridge chambers to load the needle with a predetermined packing arrangement.
