摘要：
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.
