Patent ID: 7618362

Claim:
An apparatus for delivering radioactive emissions and RF energy to an internal body location, comprising: an elongated delivery member including a distal end, a fixed portion and an actuator portion, the actuator portion of the elongated delivery member being disposed proximate to the distal end of the elongated delivery member, the actuator portion of the elongated delivery member and the fixed portion of the elongated delivery member being moveable with respect to each other; an expandable structure attached to the elongated delivery member, the expandable structure having a first end and a second end, the expandable structure is mounted proximate to the distal end of the elongated delivery member, the first end of the expandable structure being coupled to the fixed portion of the elongated delivery member, the second end of the expandable structure being coupled to the actuator portion of the elongated delivery member, the expandable structure being 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, the expandable structure defining a spatial volume that is approximately spherical when in the deployed configuration and forming an electrode of an ablation device; and a holder for a source of radioactive emissions that is approximately centrally and internally disposed within the spatial volume defined by the expandable structure when in the deployed configuration.
