Abstract
The present invention is directed to a kit for delivering x-rays to the interior surface of a body cavity. The kit includes an x-ray source and an x-ray source guidance tube. The guidance tube includes an inflatable inelastic balloon disposed about and affixed at its distal end such that when inflated, the central axis of the balloon is coaxial with and is disposed about the central axis of the tubular element. Inflation and deflation of the balloon is controllable from the proximal end of the tubular element. The x-ray source may include an electron activated target for generating x-rays in response to electrons incident on the target. The x-ray source may also includes means for generating an electron beam and steering the beam so that it is incident on the target. The target end is slidably positionable within an interior channel of the source guidance tube.
