First Claim
Patent Images
1. A brachytherapy device comprising:
- an expandable outer cage;
an expandable inner cage positioned within the outer cage and configured to receive radioactive material at its perimeter;
a movable actuator configured to cause the outer and inner cages to expand simultaneously in response to movement of the actuator between certain positions while maintaining a substantially constant and non-zero separation distance between the outer and inner cages;
a handle in which the movable actuator moves; and
a rod running through the outer and inner cages that is attached to the handle at a distal end.
