摘要：A method and catheter system for irradiating a body lumen wall whichcomprises providing an elongated, flexible radiation transmission member having anemitting portion at its distal end, advancing the emitting portion to an area adjacent thewall defining the patient's body lumen to be treated by irradiation, and directingradiation through the transmission member while moving the transmission member tocause the emitting portion to irradiate a length of the wall of the body lumen. Thetransmission member may be rotated independently or in conjunction with longitudinalmovement to achieve either selective or uniform irradiation of the wall defining the bodylumen. In one embodiment, this invention comprises an elongated flexible shaft, havingan inflatable member disposed at the distal end. A radiation transmission member havingan emitting portion on its distal end is slidably disposed within the elongated shaft sothat the emitting portion resides within the inflatable member. The system is configuredso that the emitting portion may travel at least along the length of the inflatablemember by longitudinally moving the transmission member. Optionally, the emittingportion may be configured to transmit radiation in a particular radial direction and thetransmission member may be configured to rotate axially within the lumen.
