Abstract: A brachytherapy applicator for treatment of metastic lesions in a load bearing region is provided. The applicator comprises an elongate tube body having a proximal and a distal end and defining an open internal area. A fixation element located on an outer portion of the tube allows the applicator to be fixed in position in relation to a target region while delivering a dose of therapeutic radiation. The fixation element can fix the applicator to tissue and/or a stabilization element implanted within a patient. A source of radiation positioned within the elongate body, before, during, or after implantation of the applicator, provides the therapeutic radiation.

Abstract: A brachytherapy device including a spacing member is disclosed herein. The spacing member is useful in that the instrument is effective to limit the amount of radiation that comes into contact with the sensitive tissue, and thereby protect sensitive tissue from overheating or hotspots, and/or protect against radiation exposure outside of the patient's body which may affect healthcare providers or others who might come close to the patient. In particular, the spacing apparatus is effective to control the proximity of a brachytherapy device to the outer surface of the sensitive tissue proximate to a surgical excision site.

Abstract: A radiotherapy system, and preferably a brachytherapy system, for delivering radiation to tissue surrounding an interstitial space is provided. While the system can be used for a variety of purposes, the system is preferably used to treat spinal metastases. In general, the system includes a catheter member having a proximal end, a distal end, and an inner lumen extending therethrough, and a structural support adapted to fit within an interstitial space in load bearing portion of a patient's body and having an internal space for removably receiving the distal end of the catheter member. At least one anchoring element can be disposed proximate to the distal end of the catheter. The anchoring element is preferably adapted to fit within the internal space in the structural support so as to anchor the distal end of the catheter therein.
