Abstract
Aspects herein are directed to an anchorable brachytherapy device configured to be permanently implanted in a tumor bed at the time of operative removal of the tumor. In exemplary aspects, the brachytherapy device may comprise a plurality of hollow tubes that form a spherical or ellipsoid shape. Protrusions or grooves may be formed on an outer surface of the tubes to help anchor the brachytherapy device in the tumor bed. Radioactive seeds or strands may be positioned within the tube channels to provide radiation to the tumor bed.
Claims20
A brachytherapy device comprising:
- a plurality of tubes arranged in a spherical or ellipsoid form having a fixed diameter, each tube of the plurality of tubes having a respective first end and a respective second end, wherein the first ends of the plurality of tubes are joined at a first pole of the spherical or ellipsoid form, and wherein the second ends of the plurality of tubes are joined at a second opposite pole of the spherical or ellipsoid form, the each tube having a continuous tube channel extending along at least a portion of a length of the each tube;
- and
- one or more radioactive elements positioned within one or more of the tube channels, wherein the brachytherapy device is configured to be completely enclosed within a tumor bed.
A brachytherapy device configured to be completely enclosed within a tumor bed, the brachytherapy device comprising:
- a plurality of tubes arranged in a three-dimensional (3-D) form having a fixed diameter, at least a portion of the plurality of tubes having a tube channel extending along at least a portion of a length of the tube, each tube of the plurality of tubes having a first end, a second end, and an intervening portion extending between the first end and the second end;
- and
- one or more radioactive elements positioned within one or more of the tube channels, wherein:
- respective first ends of the plurality of tubes are joined at a first location on the 3-D form,
- respective second ends of the plurality of tubes are joined at a second location on the 3-D form, and
- at least a portion of the plurality of tubes comprise a groove extending in a negative z-direction with respect to an outer surface plane of the tube.
A method of manufacturing a brachytherapy device that is configured to be completely enclosed within a tumor bed, the method comprising:
- providing a biocompatible material or a bioabsorbable material;
- forming the biocompatible or the bioabsorbable material into the brachytherapy device comprising a plurality of tubes arranged in a spherical or ellipsoid form having a fixed diameter, each tube of the plurality of tubes having a respective first end and a respective second end, wherein the first ends of the tubes are joined at a first pole of the spherical or ellipsoid form, and wherein the second ends of the tubes are joined at a second opposite pole of the spherical or ellipsoid form, the each tube having a continuous tube channel extending along at least a portion of a length of the each tube;
- and
- positioning one or more radioactive elements within one or more of the tube channels.
