Abstract
An apparatus is provided for delivering x-ray radiation to interior surface tissue of a body cavity. The apparatus comprises a flexible introducer guide having a distal end and a proximal end, the distal end for insertion into the body cavity. An inflatable balloon is mounted proximate the distal end of the flexible introducer guide and is selectively inflated to conform the balloon to the body cavity. A flexible x-ray catheter is configured for movement within the introducer guide, and an x-ray emitter is coupled to the distal end of the x-ray catheter for generating x-rays to irradiate the interior surface tissue. The x-ray emitter is also coupled to a source of high voltage. A controller is coupled to the x-ray emitter to control the area of irradiation and the dosage of radiation generated by the emitter.
