Abstract
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.
Claims30
An apparatus, comprising;
- an elongated delivery member having a distal end, a fixed portion and an actuator portion, the actuator portion being disposed proximate to the distal end, the actuator portion and the fixed portion being movable with respect to each other;
- and
- a scaffold mounted to the elongated delivery member proximate to the distal end, the scaffold having a first end coupled to the fixed portion, the scaffold having a second end coupled to the actuator portion, the scaffold 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.
An apparatus, comprising:
- a scaffold having a stowed configuration and a deployed configuration;
- a first delivery member attached to the scaffold;
- and
- a second delivery member attached to the scaffold such that relative movement between the first delivery member and the second delivery member moves the scaffold from the stowed configuration to the deployed configuration.
An apparatus for delivering radioactive emissions and RF energy to an internal body location, comprising:
- an elongated delivery member;
- an expandable structure attached to the elongated delivery member, the expandable structure defining a spatial volume that is approximately spherical when in a deployed configuration and forming an electrode of an ablation device;
- and
- a holder for a source of radioactive emissions that is disposed approximately centrally to the spatial volume defined by the expandable structure when in a deployed configuration.
An apparatus, comprising:
- an elongated delivery member;
- an expandable structure coupled to the elongated delivery member, the expandable structure having a stowed configuration and a deployed configuration;
- a radiation source locating feature;
- and
- a radiation source, the elongated delivery member defining a range of motion of the radiation source including an end location, the end location corresponding to the radiation source being in contact with the radiation-source-locating feature and within the expandable structure when in the deployed configuration.
