Abstract
A system for treating tissue surrounding a resected cavity that is subject to a proliferative tissue disorder is provided. The system includes a tissue fixation device including a catheter body member having a proximal end, a distal end, an inner lumen, and an expandable surface element disposed proximate to the distal end of the body member, the expandable surface element sized and configured to reproducibly position tissue surrounding a resected tissue cavity in a predetermined geometry upon expansion. After expansion of the expandable surface element within a resected tissue cavity, an external radiation device positioned outside the resected cavity delivers a dose of radiation to the tissue surrounding the expandable surface element.
