The spacer element includes a center section and two cup-like end sections, the spacer member generally being cylindrical in exterior configuration. The center section is approximately 40-50 mm long, with the two end sections being approximately 10-15 mm long. The spacer element is also configured to fit within a conventional needle which is loaded with an alternating succession of radioactive seeds and spacer elements, for subsequent positioning in the prostate.
