Abstract
A dual lumen catheter system for the positioning of a radioactive material for therapeutic radiation treatment of the body is disclosed. The dual lumen catheter includes a guidewire lumen and a blind lumen provided for introduction of a radiation source wire. The dual lumen catheter provides the advantage that the radiation source wire does not contact body tissue thereby eliminating the need for sterilization of the wire for reuse. Also disclosed are a radiation source wire having a tapered distal end of the wire core such that radioactive material and other components of the source wire can be applied to the outer surface thereof without exceeding a predetermined maximum outside diameter. Also disclosed is a source train cask for use with the catheter system and radiation source wire of the invention. The source train cask permits convenient handling and feeding of the radiation source wire without exposure of the medical personnel to radiation.
