Title:
BRACHYTHERAPY, DEVICES AND METHODS OF USING THEM
Document Type and Number:
WIPO Patent Application WO2004064916
Kind Code:
A3
Abstract:
Brachytherapy devices are provided for delivering a substantially uniform dose rate of radiation to a treatment area at a predetermined treatment depth. The devices include a holder defining a cavity, and a radioactive material located within the cavity. The holder comprises radiation-shielding material therein. The holder and the radioactive material are positioned to cooperatively provide a substantially uniform dose rate of radiation to a treatment area at a predetermined treatment depth. Also disclosed are methods for treating macular degeneration or ocular melanoma. The methods involve positioning a brachytherapy device in contact with or in close proximity to tissue located in a treatment area and exposing the tissue located in the treatment area to a therapeutic dose of radiation, which is delivered at a substantially uniform dose rate over the treatment area at a predetermined treatment depth.
