Patent ID: 8475353

Claim:
A brachytherapy treatment apparatus, comprising: an elongate core member comprising proximal and distal ends defining a central longitudinal axis therebetween; a pair of elongate members comprising elongate member proximal ends and elongate member distal ends and pathways extending between the elongate member proximal ends and the elongate member distal ends for receiving a source of radiation therealong, the elongate member distal ends coupled to the distal end of the elongate core member; an actuator coupled to the elongate members adjacent distal portions of the elongate members and movable axially relative to the elongate core member for moving the distal portions of the elongate members between a collapsed configuration wherein the distal portions of the elongate members extend substantially parallel to the elongate core member, thereby defining a plane within which the distal portions of the elongate members lie, and an expanded configuration wherein the distal portions of the elongate members bow away from one another while remaining substantially within the plane; and wherein there are no elongate members adjacent the elongate core member on a first side of the plane when the elongate members are in both the collapsed configuration and the expanded configuration.
