CA 2276893

A device and method for precisely delivering dosage of radiation from a radiation source to a treatment site of a vessel is provided herein. In one embodiment, the device includes a catheter which inserts into a vessel lumen of the body. The catheter includes an adjuster section for altering a portion of the radiation emitting radially from the radiation source so that the radiation source delivers an asymmetrical radiation profile to the vessel. The device can also include a catheter supporter which inhibits rotational deformation in the catheter between a catheter distal end and a catheter proximal end. This allows the delivery section to be precisely rotated to properly position the adjuster section within the vessel lumen.
