Abstract
Combination radiation delivery and chemotherapy devices comprise bioabsorbable structures with radionuclides and chemotherapeutic agents immobilized on said structures. The bioabsorbable structures have a predefined persistence period which is usually substantially greater than the half-life of the radionuclides, thus assuring that the radionuclides remain localized and sequestered at a desired target site while significant radioactivity remains. The radiation delivery and chemotherapy devices are suitable for a wide variety of medical purposes, being particularly suitable for the treatment of solid tumors by injection or open surgical introduction of the devices at a target site. Kits comprising the devices together with instructions for use are also provided.
