Abstract:
A tissue radiation device assembly which is adapted to deliver radiation to a region of tissue at a desired location along a body space wall which defines at least a portion a body space in a patient, comprising:a radiation member with a radiation source;a first delivery member with a proximal end portion and a distal end portion which is adapted to engage the radiation member;a second delivery member with a proximal end portion, a distal end portion, and a radiation passageway extending between a proximal port along the proximal end portion and a distal location along the distal end portion of the second delivery member wherein the radiation passageway is substantially closed in a fluid tight seal, the radiation passageway being adapted to slidably receive the first delivery member such that the radiation member engaged to the first delivery member may be positioned proximally of the distal location; anda third delivery member with a proximal end portion, a distal end portion, and a guidewire passageway extending between a distal guidewire port along the distal end portion of the third delivery member and a proximal guidewire port along the third delivery member proximally of the distal guidewire port,the guidewire passageway being adapted to slidably engage a guidewire through the proximal and distal guidewire ports and also to track over the guidewire into the body space such that the distal end portion of the third delivery member is positioned at the desired location, and the guidewire passageway also being adapted to slidably receive the second delivery member such that the distal end portion of the second delivery member may be positioned along the distal end portion of the third delivery member and within the body space at the desired location.
