Abstract
A brachytherapy system for treating metastases on and around a patient's spinous process is provided. The device generally includes a catheter member having a proximal portion, a distal portion, and at least one lumen extending therethrough. The distal portion of the catheter member includes first and second branch members that are adapted to be positioned on opposed sides of a patient's spinous process. The device further includes first and second elongate anchoring elements disposed on the first and second branch members, and optionally can include at least one centering mechanism disposed within each of the first and second anchoring elements. The first and second anchoring elements are preferably adapted to be positioned between a spinous process and transverse process of at least one vertebral body, and to extend along a length of a patient's spinal column, such that the first and second anchoring elements, when expanded, engage and anchor the first and second branch members between the spinous process and transverse process of at least one vertebral body.
