ABSTRACT:
Medical instrument for implantation of radioactive seeds in a body, the instrument including an elongated support rod and an elongated stylet rod spaced apart from and parallel to the support rod, and being held in that relationship by a stop block and a slide block spaced apart from each other and longitudinally slidable with respect to both the support rod and the stylet rod. The stop block is attached to the support rod and the slide block is clampable to each of the support rod and the stylet rod. A seed cartridge with transverse spaced passageways and a central longitudinal through bore receives, stores, and discharges a plug of spaced radio-active seeds by the stylet rod through a connectible hollow elongated implantation needle through which the plug may be implanted in body tissue.
