ABSTRACT:
A large capacity seed cartridge is provided for a radiation therapy seed applicator. The seed cartridge is adapted for use with the Mick applicator, or other conventional applicators. The cartridge includes a housing with a seed drum mounted therein. A seed track extends around the seed drum. A spring operatively urges the seed in the track towards a discharge opening in the seed drum. A seed pusher rod in the applicator pushes each seed out of the opening and into the needle which is positioned in the patient, such that the seed is implanted into the body of a patient. The seed cartridge can be quickly and easily installed in the applicator and holds 120 radioactive seeds, or more.
