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.

A method for providing intravascular brachytherapy includes the step of positioning a radiation source within a target area to be radiation and orienting the attenuator found on the catheter. Once the attenuator or shield is properly oriented, a reference or normalization point or marker ( ) is selected. This reference marker ( ) can placed, as one example, on the external elastic lamina closest to catheter ( ) and can serve as a reference point for the brachytherapy treatment. Several other points of interest can be is selected ( ) on the image ( ) or images that have been gathered of the treatment site, with dosage levels ( and ) being display automatically on the display ( ) close to the IVUS image ( ).

A delivery device and method for delivering a dosage of radiation from a radiation source to a treatment site of a vessel is provided herein. The delivery device includes a catheter and a delivery area. The catheter is suitable for being inserted into a vessel lumen of the vessel and includes a delivery lumen for receiving the radiation source. The delivery area also receives the radiation source. The delivery area includes an attenuator section for attenuating a portion of the radiation emitting from the radioactive area so that the delivery area emits an eccentric radiation profile. The delivery 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 area to be precisely rotated to properly position the attenuator section within the vessel lumen.
