Apparatus and method for providing a double balloon breast brachytherapy device

摘要

According to one general aspect, there is an double-balloon breast brachytherapy catheter comprising, an outer-balloon that is filled with a liquid substance or air via an out-balloon-filler; an inner-balloon that is filled with a liquid substance or air via an inner-balloon-filler, wherein the inner-balloon is inserted inside the outer-balloon; a plurality of radiation-tubes connected to an outside boarder of the inner balloon; a vacuum-tube that is wrapped around an exterior of the outer-balloon, wherein the vacuum tube is used to remove human fluids and air to create a void; and a flexible-shaft is connected to an upper-head, a proximal-tail and a distal-tip, wherein the upper-head is covered by the outer-balloon, the inner-balloon, the plurality of radiation-tubes and the vacuum-tube.

主权项

1. A double-balloon breast brachytherapy catheter, comprising:
an outer-balloon configured to be filled with a liquid substance or air via an outer-balloon-filler to selectively adjust an outer balloon size; an inner-balloon configured to be filled with a liquid substance or air via an inner-balloon-filler 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 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 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 as said flexible radiation-tubes are moved into a radiation-delivery position by said inner-balloon, wherein the outer balloon size and the inner balloon size are selectively adjusted independent of each other, and the radiation-delivery position is varied by said inner-balloon, to optimize radiation delivery.
