Abstract:
1. A brachytherapy device for treating tissue within a cavity of a body comprising: a first set of tubes configured to be inserted into the cavity through an opening at the surface of the body, each of the first set of tubes having an external end and an interior channel beginning at the external end that is configured to receive radioactive material, the external ends of the first set of tubes being bundled together and lying in substantially the same plane and protruding from the opening in the surface of the body while the first set of tubes are in the cavity; a seal configured to prevent fluid that originates from the cavity from entering into the external ends of the first set of tubes while they protrude from the opening in the surface of the body, the seal comprising a substantially flat gasket that is pressed against the external ends of the first set of tubes, and the gasket comprising a plurality of openings, each of which is aligned with one of the channels in the first set of tubes so as to allow radioactive material to be inserted into the channels of the first set of tubes while preventing fluid that originates from the cavity from entering into the external ends of the first set of tubes; a fastener configured to fasten the gasket to the tubes; and a hollow tube surrounded by the ends of the first set of tubes and running substantially parallel to the full length of the first set of tubes, wherein the gasket includes a central opening and the fastener includes a screw having a shaft that passes through the central opening in the gasket and into the hollow tube.
