Abstract
Described here are brachytherapy applicators that comprise a modular support matrix. The modular support matrix may define the arrangement of radiation source lumens within the brachytherapy applicator. The modular support matrix can be adjusted to position the radiation sources to obtain a certain dose and dose profile. A series of modular support matrices may be operably connected according to patient anatomy or dosing requirements. Systems and methods for using such modular brachytherapy applicators are also described.
Claims64
A gynecological brachytherapy applicator comprising an elongate cylindrical body having a proximal end and a distal end, the elongate body comprising a modular support matrix having a plurality of source lumens extending at least partially therethrough and defining an arrangement of the source lumens within the elongate body.
A brachytherapy system comprising a plurality of stacking components, at least one hub, and at least one removable handle.
A brachytherapy system comprising:
- a gynecological applicator, the applicator comprising an elongate cylindrical body having a proximal end, a distal end, and a support matrix, the support matrix comprising a wall and defining a lumen between the proximal and distal ends, wherein the support matrix has an unexpanded configuration and a radially expanded configuration, and a plurality of source lumens within the wall;
- and
- one or more dilators for expanding the support matrix.
A method for delivering radiation therapy to a gynecological tissue comprising:
- advancing a gynecological brachytherapy applicator adjacent to a target tissue, the gynecological brachytherapy applicator comprising an elongate cylindrical body having a proximal end and a distal end, the elongate body comprising a modular support matrix having a plurality of source lumens extending at least partially therethrough and defining an arrangement of the source lumens within the elongate body;
- and
- delivering radiation therapy to the target tissue using the brachytherapy applicator.
