Abstract:
1. A brachytherapy treatment apparatus for treating tissue surrounding a cavity within a body, comprising: an elongate body comprising a proximal end and a distal end configured for introduction into tissue; and a plurality of elongate members extending between the proximal end and the distal end and comprising pathways that extend from the proximal end to the distal end for receiving a source of radiation therealong, distal portions of the elongate members being movable from a collapsed configuration for introduction through a tissue tract to a target location to an expanded configuration, the distal portions of the elongate members comprising tubular bodies and lateral surfaces extending from the tubular bodies, the lateral surfaces comprising a pair of wings extending laterally from each tubular body, wherein the tubular bodies define an outer cross-sectional dimension and the wings define a substantially uniform thickness that is smaller than the outer cross-sectional dimension, wherein tips of the wings are spaced apart from adjacent elongate members in the expanded configuration, and wherein the wings extend from the tubular bodies such that each elongate member defines an outer surface extending between tips of the wings, the outer surface being substantially flat or arc-shaped and extending substantially continuously between the tips of the wings.
