Abstract:
1. A brachytherapy treatment apparatus for treating tissue at a target location within a patient's breast, comprising: an elongate body comprising a proximal end and a distal end configured for introduction into a tract through tissue having a length such that, when the distal end is introduced through a patient's breast into a lumpectomy cavity, the elongate body proximal end remains outside the patient's breast adjacent the breast; one or more coil members on the distal end, each coil member comprising a lumen defining a spiral pathway for receiving a source of radiation therealong, the one or more coil members movable between a collapsed configuration for introduction through a tissue tract to a target location, and an expanded configuration at the target location; an actuator comprising a proximal end adjacent the elongate body proximal end and a distal end coupled to the one or more coil members, the actuator translatable at least one of rotationally and axially for directing the one or more coil members between the collapsed and expanded configurations within the lumpectomy cavity; and an HDR source of radiation introduceable through each lumen for delivering radiation to the target location.
