Abstract: The directional-ionizing energy emitting implant is for attachment either to natural tissue or a prosthetic device, and delivers a prescribed dosage of energy to targeted tissue. The insert device includes an energy-source material within the insert device that delivers the prescribed dosage of energy to the targeted tissue, while minimizing exposure of nontargeted tissue. The targeted tissue has a known energy-response profile and is adjacent to the targeted tissue. The energy-source material in combination with the prosthetic device defines an actual energy-delivery distribution field. The energy-delivery distribution field has a configuration similar to the known energy-responsive profile of the targeted tissue. The prescribed dosage of energy is applied from energy-source material within the insert device and directed to the targeted tissue.

Abstract: An implant system and a method for delivering a dosage of radiation to targeted tissue. The system comprises a prosthetic device that functionally replaces or is additive to a body structure or joint, and a radio source material. The radio source material is positioned either on or within the prosthetic device. The actual radiation delivery distribution field has a similar configuration to the profile of the targeted tissue. The implant system is particularly useful for inhibiting heterotopic ossification.

Abstract: A catheter apparatus filled with a radiation carrier material such as an inert radioactive gas for the treatment of restenosis after angioplasty, and malignancies. The inflated catheter includes a plurality of discrete chambers for transporting the radioactive carrier material, and a plurality of discrete chambers enabling substantial blood flow through the artery during treatment with the prescribed radiation. The inflated catheter may also comprise one unit balloon. A specific metal coating enhances the radiation dose delivered to the target. The wall of the lumen attenuates transmission dose to the blood circulating through the hollow inner lumen of the catheter device. The system also creates increased by-product radiation, from the impact of beta particles and gamma protons traveling toward the lumen wall.

Abstract: A system, apparatus, and method for administering radiation internal to a patient involving a catheter, having disposed therewithin a radiation carrier material such as an inert radioactive gas, like xenon, for the treatment of restenosis after angioplasty, and malignancies. When the catheter apparatus is inflated, it may include a plurality of discrete chambers for transporting the radioactive carrier material, and a plurality of discrete chambers enabling substantial blood flow through the artery during treatment with the prescribed radiation.
