  • Brachytherapy device having an alignment and seal adaptor
    Patent number: 8257241
    Abstract: A brachytherapy device for treating tissue within a cavity of a body. The device may include a first set of tubes configured to be inserted into the cavity through an opening at the surface of the body. Each of the tubes may have an external end and an interior channel beginning at the external end that is configured to receive radioactive material. The external ends of the tubes may be bundled together. The tubes may be of a length that causes the external ends to be near the opening in the surface of the body while the tubes are in the cavity. A seal may be configured to prevent fluid that originates from the cavity from entering into the external ends of the tubes while they are near the opening in the surface of the body. The seal may include a gasket that is pressed against the external ends of the tubes. The gasket may have openings that align with channels within the external ends of the tubes.
