Abstract
A bioabsorbable brachytherapy device includes a tubular housing with sealed ends and an enclosed radioactive material. The radioactive material includes a radioisotope, such as palladium-103 or iodine-125. The tubular housing is made from a biocompatible and bioabsorbable polymeric material, and is sealed by means such as heat welding or solvent fixing. The device may further include a radiopaque medium and one or more therapeutic drugs.

A brachytherapy device for use in radiation treatment of an affected tissue region, the brachytherapy device comprising:
- a radioactive material comprising a radioisotope;
- a bioabsorbable polymeric housing for containing the radioactive material, the housing being formed by at least one tube having an axis and two ends, the at least one tube being sealed at each end.
A method for radiation treatment of an affected tissue region in a patient, the method comprising:
- obtaining a radioactive material comprising a radioisotope;
- fabricating a bioabsorbable polymeric housing to contain the radioactive material, the housing being formed by at least one tube having an axis and two ends;
- placing the radioactive material within the at least one tube comprising the polymeric housing;
- and
- placing the polymeric housing containing the radioactive material in the affected tissue region of the patient.
