Abstract
A brachytherapy apparatus includes a distal support member and a proximal support member movable relative to the distal support member. The apparatus includes a plurality of elongate treatment members having distal first locations coupled to the distal support member, proximal second locations coupled to the proximal support member, and pathways between the proximal second locations and the distal first locations adapted to receive one or more radiation sources. Each of the treatment members is movable between a generally straight configuration and a curvilinear configuration. An expandable member encloses and provides a spatial volume for the plurality of the treatment members and is adjustable between a contracted configuration and an expanded configuration.
