Abstract
An applicator system for interstitial radiation therapy that uses a brachytherapy needle assembly for simultaneously dispensing an effective amount of medicine, such as anti-inflammatory agents, along with radioactive seeds. A medicine cartridge or a modified seed cartridge, having a reservoir on its proximal end, can be attached to the applicator body for dispensing medicine into a needle or medicine can be injected into the needle via a three-way fitting attached to the applicator body. Alternatively, a modified stylet having a reservoir on its proximal end containing medicine can be used to deliver medication to a needle. Additionally, the brachytherapy needle or the radioactive seeds and spacers can be coated with medication that would be absorbed by the body upon implantation.
