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 device adapted for use with a radiation source positioned within a vessel of a patient, the device comprising an adjuster section adapted to be positioned within the vessel proximate to the radiation source, the adjuster section being adapted to alter the intensity of a portion of the radiation emitting radially from the radiation source so that the vessel receives a radiation dose profile relative to the radiation source which is substantially asymmetrical and so that two equidistant, spaced apart points relative to the radiation source on the radiation dose profile have a difference in radiation dose of between one percent and ninety-nine percent.
The device of clam 7 wherein the attenuator section includes a plurality of adjacent attenuator segments.
A device for treating a vessel in a human, the device comprising a radiation source adapted to be positioned within the vessel, the radiation source emitting an asymmetrical radiation dose profile relative to the radiation source so that at least two equidistant, diametrically opposed points relative to the radiation source on the radiation dose profile have a difference in radiation dose of between one percent and ninety-nine percent.
