Abstract
Apparatus, systems, and methods are provided for delivering brachytherapy into a target tissue region, e.g., a breast. In some embodiments, a flexible brachytherapy device is implanted that includes a therapy delivery portion having one or more radioactive sources securely retained thereto, and a tail portion extending from the therapy delivery portion. The brachytherapy device may be implanted in a helical configuration within the target tissue region. To assist in placement and removal of the brachytherapy device, a tubular sheath may be implanted by attaching (e.g., sliding over) a helically coiled needle that is advanced into the body by screw-like rotation. Once implanted, the sheath and the brachytherapy device may extend outside the body, where they may be folded and secured flat against the skin. The device and sheath may be removed at therapy completion.
