<p>A multi-lumen balloon (10) for use in a flutes balloon centering catheter (1) and method for providing the same. The multi-lumen balloon maintains a radiation source (25) at the center of a cardiovascular artery, has improved blood perfusion capability, and has improved balloon refolding characteristics. The method of fabricating a multi-lumen balloon designed for a radiation centering uses an improved extrusion process that allows the manufacture of the multi-lumen balloon sub-assembly to be done separately from the catheter shaft assembly.</p> |
