US 12,594,436 B2 · Brachytherapy source assembly

Abstract

Embodiments of the disclosure may be drawn to brachytherapy source assemblies. Exemplary source assemblies may include a cable made of an electrically non-conductive material and a guide wire coupled to and extending from a distal end of the cable. The guide wire may have a distal end region and a proximal end region, and the guide wire may have a length that is shorter than a length of the cable. The assembly may also include a capsule located at a distal end region of the guide wire, and the capsule may include a chamber configured to contain a radioactive source. The capsule may be formed of a non-ferromagnetic material and may have a ferromagnetic coating that at least partially covers the capsule.

Dependent claims

A brachytherapy source assembly for delivering brachytherapy treatment, the source assembly comprising:

a cable made of an electrically non-conductive material, the cable having a proximal end and a distal end;
a guide wire having a proximal end coupled to and extending from the distal end of the cable, the guide wire having a distal end region and a proximal end region, and the guide wire having a length that is shorter than a length of the cable;
and
a capsule located at a distal end region of the guide wire, the capsule including a chamber configured to contain a radioactive source, wherein the capsule is formed of at least one of a non-ferromagnetic material or austenitic 316 steel.
