摘要:
The present invention includes a device for X-ray treatment in a passage, a method for positioning an X-ray emitter at a treatment area in the passage, a method for exposing a length of the treatment area, and a method for moving a catheter automatically. In addition, the present invention includes a bellows valve adapter and a hemostasis valve adapter that allows fluid to circulate between a sheath and an X-ray emitter within the device and allows movement of the X-ray emitter within the sheath. Further, the invention includes a catheter pullback assembly for retracting or advancing an X-ray emitter, a system for X-ray treatment in a body, and a treatment system for controlling an X-ray emitter.

A cathode structure comprising a getter material provided with a diamond film. The getter material may include zirconium, vanadium and iron. Cathode structures may have a substantially rounded configuration including a substantially straight portion. Other cathode structures may have a substantially flat portion, with the diamond film covering essentially the entire flat surface. Methods of manufacturing cathode structures may include conditioning the cathode structure by applying a voltage.

An apparatus and method for exposing a treatment site in a patient to x-ray radiation is described that uses a pulse voltage source, where the x-ray emitter employs a cold cathode. The invention may further include a current sensor for measuring a current through the x-ray emitter, and, optionally, a current integrator connected to the current sensor. Each voltage pulse may be discontinued when a predetermined amount of charge has passed through the emitter. The step of moving an x-ray emitter past a treatment area at a rate determined by the amount of charge that has passed through the emitter is also described. The present invention also includes an x-ray emitter device with rectangular voltage pulses added to a base direct current voltage. Another step of the invention may be applying a voltage pulse cycle to the x-ray emitter where a duration of the pulse is 2-5 times lower than a thermal relaxation time of an emitter.
