ABSTRACT:
A radiation source for delivering a dose of radiation to a treatment site of a vessel is provided herein. The radiation source includes a delivery wire and a radioactive segment. The radioactive segment includes a substantially coiled or entwined radioactive wire which allows the radioactive segment to have a relatively large surface area to volume ratio. The delivery wire is made of material having a relatively short half-life, such as titanium, while the radioactive segment is made of a material, such as a rhenium or yttrium, which has a much longer half-life.
