Apparatus and method for providing a double balloon breast brachytherapy device

A method for treating a patient by operating a double-balloon brachytherapy catheter, comprising the steps of:

• filling a liquid substance or air into an outer-balloon via an outer-balloon-filler to selectively adjust and achieve an outer balloon size;
• filling a liquid substance or air into an inner-balloon via an inner-balloon-filler to selectively adjust and achieve an inner balloon size, wherein said inner-balloon is positioned inside said outer-balloon, a plurality of flexible radiation-tubes being positioned within said outer-balloon and positioned by said inner-balloon;
• changing angles and lengths of each of said flexible radiation-tubes proportional to a size of said inner-balloon by filling said inner-balloon via said inner-balloon-filler with the liquid substance or air, a change in size of said inner-balloon changing the angles and the lengths of said flexible radiation-tubes;
• selectively controlling the outer balloon size and the inner balloon size mutually independently;
• and
• loading radioactive material into at least one of said plurality of flexible radiation-tubes to provide a radiation dose treatment.

A double-balloon brachytherapy catheter, comprising:

• an outer-balloon configured to be filled with a liquid substance or air to selectively adjust an outer balloon size;
• an inner-balloon configured to be filled with a liquid substance or air to selectively adjust an inner balloon size, wherein said inner-balloon is positioned inside said outer-balloon;
• and
• a plurality of flexible radiation-tubes positioned by said inner-balloon and adapted to receive a corresponding radiation source, each of said flexible radiation-tubes configured to change in angles and lengths proportional to a size of said inner-balloon by filling said inner-balloon with the liquid substance or air, a change in size of said inner-balloon changing the angles and the lengths of said flexible radiation-tubes as said flexible radiation tubes are moved into a radiation-delivery position by said inner-balloon, the plurality of said flexible radiation-tubes being positioned within said outer-balloon and adapted to move into the radiation-delivery position within said outer-balloon by the filling of said inner-balloon with the liquid substance or air,
• wherein said inner-balloon selectively positions said flexible radiation-tubes within said outer-balloon, the radiation-delivery position is selectively varied by said inner-balloon, and the outer balloon size and the inner balloon size are selectively adjusted independent of each other, to optimize radiation delivery by the corresponding radiation source.
