Abstract:
A brachytherapy treatment apparatus for treating tissue surrounding a cavity within a body includes an elongate body comprising a proximal end and a distal end sized for introduction into a tract through tissue and a plurality of tubular members on the distal end comprising lumens for receiving a source of radiation therein. The tubular members are movable from a collapsed configuration for introduction through a tissue tract to a target location, and an expanded configuration for providing a three dimensional array of pathways at the target location. A plurality of openings communicating with respective lumens for inserting the source of radiation into the lumens are provided and a hub is coupled to proximal ends of the tubular members. The hub is movable relative to the elongate body for moving the tubular members from the collapsed configuration to the expanded configuration. An actuator for moving the hub relative to the distal end is also provided.
