United States Brief Statement
Cesium-131 brachytherapy seeds are indicated for the treatment of malignant disease(e.g., head and neck, eye, brain, breast, prostate, etc.) and may be used in surface, interstitial, and intra cavitary applications for tumors with known radio sensitivity. The seeds may be used as a primary treatment or in conjunction with other treatment modalities, such as external beam radiation therapy, chemotherapy or as treatment for residual disease after excision of primary tumors. Contraindications: As with other brachytherapy sources, treatment of tumors in generally poor condition (e.g. ulcerated) is not recommended with Cesium-131 brachytherapy seeds due to the potential for source migration. Prior to use, please reference the Cesium-131 Instructions for more information on indications, contraindications, warnings, all precautions, and adverse events.
Caution: Federal law restricts this device to sale by or on the order of a physician.
