Patent ID: 8353812

Claim:
Apparatus for delivery of a radiation treatment source comprising: a first module; a second module adapted to be removably associated with the first module and adapted to receive a radiation treatment source comprising a source wire with a radioactive source carried at the distal end of the source wire; a cannula extending from one of the first module and the second module; an advancement mechanism associated with the first module and cooperatively engageable with the second module, the advancement mechanism being operable to advance a radiation treatment source disposed within the second module from a first, retracted position wherein the radiation treatment source is located fully within the second module and a second, treatment position wherein the radiation treatment source extends into the cannula and the radioactive source is located at a selected position within the cannula a remote actuator; and a flexible umbilicus operatively connecting the remote actuator and the advancement mechanism, the remote actuator and flexible umbilicus being operable to transmit a force to the advancement mechanism for selective movement of the radiation treatment source between the first and second positions.
