A system for selectively loading and sealing a plurality of bioresorbable tubes for low dose radioisotope seeds, the bioresorbable tubes each having a closed distal end and a proximal open end. The system comprises a loading station that permits a user to load a selectable arrangement of elements, including at least one radioactive seed, and at least one spacer through the proximal open end of each bioresorbable tube, and a finishing station that selectively seals the proximal open end of each bioresorbable tube at a sealing position generally adjacent to a proximal end of the electable arrangement of elements.
