Abstract
A radiation delivery catheter with inflatable chambers which provide a layer of radiation of minimum effective dose possible to be delivered as close as possible to the origin of disease within a blood vessel. The device can be centered within the true lumen of a vessel to provide even dispersion of the radiation agent to the outer wall of the vessel. The catheter comprises two central self centering balloons, one thin radiation agent inflatable chamber, and one radiation spread cloaking inflatable chamber with high strength properties resistant to rupture.
