Abstract
An apparatus for treating a body structure with radiation and a method for using the same. The apparatus comprising a concentrator for receiving a solution comprising a radioactive material and for increasing the concentration of the radioactive material in solution; a calibrator operatively associated with the concentrator for measuring a level of radiation associated with the radioactive material; and a delivery unit for transferring the solution directly from the apparatus to a balloon catheter.
Claims100
An apparatus for treating a body structure with a radioactive material comprising:
- a. a concentrator for receiving a first solution comprising a radioactive material and for producing a second solution comprising the radioactive material, the second solution having a greater concentration of the radioactive material than the first solution;
