Abstract
Disclosed is a closed lumen catheter for facilitating placement of a radiation source within a vessel. A distal portion of at least a first lumen and a second lumen are separated by a moveable wall, allowing a reduced catheter shaft profile. Centering structures, such as one or more inflatable balloons, with perfusion, may be added. Methods are also disclosed.
