Abstract:
1. A brachytherapy treatment apparatus, comprising: an elongate body comprising a proximal end and a distal end configured for introduction into a tract through tissue to a target location within a patient's body; a plurality of elongate members comprising a distal portion adjacent the distal end and a proximal portion configured to extend from the patient's body when the distal portion is introduced into the target location, the elongate members comprising lumens extending from openings in the proximal portion to the distal portion for receiving a source of radiation therealong, the distal portion of the elongate members being movable from a collapsed configuration for introduction through a tissue tract to a target location, and an expanded configuration; and a plurality of marker devices removably receivable into the openings and along the lumens of respective elongate members, each marker device comprising an elongate solid cable, wherein the marker devices are receivable within the lumens such that the marker devices extend through the lumens to the distal portion of the elongate members, and wherein the marker devices comprise end caps for engaging the openings in the elongate members when the marker devices are received within the lumens to substantially seal the lumens.
