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.
5. The method of claim 4 , further comprising the step of:
selectively filling said outer-balloon to fill a cavity volume for the radiation dose treatment.
6. The method of claim 5 , further comprising the step of:
positioning said flexible radiation tubes by changing the angles and the lengths of each of said flexible radiation-tubes by filling said inner-balloon with the liquid substance or air to provide a corresponding said inner balloon size that corresponds to a radiation-delivery position to optimize radiation delivery based on a treatment plan.
7. The method of claim 6 , further comprising the step of:
removing by a vacuum-tube fluids or air from a cavity receiving the double-balloon brachytherapy catheter.
8. The method of claim 4 , further comprising the step of:
removing by a vacuum-tube fluids or air from a cavity receiving the double-balloon brachytherapy catheter.
9. The method of claim 4 , further comprising the steps of:
inserting into a cavity a shaft that is connected to said outer-balloon, said inner-balloon, said flexible radiation-tubes and a vacuum-tube; and
removing fluids or air from the cavity receiving the double-balloon brachytherapy catheter using the vacuum-tube.
10. 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;
