Abstract:
1. A brachytherapy treatment apparatus, comprising: an elongate core member comprising proximal and distal ends, a proximal portion, and a distal portion configured for introduction into a tract through tissue and terminating in a distal tip; a plurality of elongate members, each elongate member comprising a distal end coupled to the core member distal end, a proximal end movable relative to the core member, and a pathway extending between the elongate member proximal and distal ends for receiving a source of radiation therealong, the elongate member proximal ends being movable relative to the distal ends for expanding the elongate members from a collapsed configuration to an expanded configuration such that the elongate members are directed radially outwardly away from the distal portion of the core member; an expandable member comprising a proximal end coupled to the core member adjacent the elongate member proximal ends and a distal end coupled to the distal tip of the core member such that the expandable member surrounds the distal portion of the core member, the elongate members extending along and unsecured to an outer surface of the expandable member in the collapsed configuration; and an actuator hub coupled to the elongate members and an elongate actuator member extending proximally from the hub that is movable axially relative to the core member for expanding the elongate members independently of the expandable member such that the elongate members are expanded away from the expandable member only by actuating the actuator member independently of the expandable member while the expandable member remains in an unexpanded condition.
