Radioactive 133-Xenon Gas-Filled Balloon to Prevent Restenosis: Dosimetry, Efficacy, and Safety Considerations
2002
Circulation
Background-Ionizing radiation administered intraluminally via catheter-based systems using solid  and ␥ sources or liquid-filled balloons has shown reduction in the neointima formation after injury in the porcine model. We propose a novel system that uses a 133-Xenon ( 133 Xe) radioactive gas-filled balloon catheter system. Methods and Results-Overstretch balloon injury was performed in the coronary arteries of 33 domestic pigs. A novel 133 Xe radioactive gas-filled balloon (3.5/45 mm) was
