Spacer apparatus for radiation and ablation therapy

摘要

An apparatus comprises an elongated delivery member and a scaffold. The elongated delivery member has a distal end, a fixed portion and an actuator portion. The actuator portion is disposed proximate to the distal end. The actuator portion and the fixed portion are movable with respect to each other. The scaffold is mounted to the elongated delivery member proximate to the distal end. The scaffold has a first end coupled to the fixed portion. The scaffold has a second end coupled to the actuator portion. The scaffold is changeable between a stowed configuration and a deployed configuration by movement of at least the actuator portion and the fixed portion relative to each other.
