Abstract
An intravascular catheter having an expandable inflation region adapted for centering a radiation dose in a body lumen for a period of time sufficient to permit delivery of a radiation dose to the body lumen. The catheter includes a delivery lumen, and a blind internal lumen for receiving a wire having a radiation source located at the distal end of the wire. The blind internal lumen is received in the delivery lumen of the catheter. The blind internal lumen prevents contamination of the radiation source by fluids from the body lumen. The radiation source is advanced through the blind internal lumen towards the inflation region of the catheter. The inflation region includes a plurality of balloon lobes at the distal end of the catheter. The plurality of balloon lobes, when inflated, can center the radiation source within a curved section of the body lumen.
