Apparatus for brachytherapy

摘要

A double-balloon brachytherapy catheter includes an outer-balloon that is filled with a liquid substance or air via an outer-balloon-filler. Further, an inner-balloon is filled with a liquid substance or air via an inner-balloon-filler, with the inner-balloon inserted inside the outer-balloon. Additionally, a plurality of radiation-tubes is positioned in association within the inner-balloon, such as to an outside border of the inner-balloon and within the outer-balloon. Each radiation-tube out of the plurality is segmented into segments of differing hardness. In addition, a vacuum-tube can be wrapped around an exterior of the outer-balloon, where the vacuum tube is used to remove fluids and air to create a void. Also, the plurality of radiation-tubes can be configured to run longitudinally along a central shaft of the double-balloon brachytherapy catheter.

主权项

1. A double-balloon 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 radiation-tubes, each radiation-tube being segmented and arranged longitudinally into segments of differing hardness, said plurality of radiation-tubes positioned in association with and moved into a corresponding radiation-delivery position by said inner-balloon, wherein the outer balloon size and the inner balloon size are mutually independent and selectively adjusted independent of each other, and each radiation-tube of said plurality of radiation-tubes is selectively adjustable to the corresponding radiation-delivery position by varying the inner balloon size to optimize radiation delivery.
