    摘要： An apparatus for emitting x-rays comprises a housing which contains an anode having an electron receiving surface and a cathode having an electron emitting surface. A cable couples the anode to a source of high voltage. An optical fiber secured to the cable has a proximal end coupled to a source of optical energy and a distal end configured to direct the optical energy onto the cathode's electron emitting surface. The cathode emits electrons which strike the anode to create x-ray radiation.

    摘要： An emitter for a miniature X-ray apparatus comprises an insulating shell, an anode, and a cathode. The insulating shell includes a conical brazing surface, brazed to a conical brazing surface on the anode. The braze consists of a pure titanium layer and a pure tin layer. During brazing, the pure metals react and bond to the insulating shell and create a titanium-tin alloy between the pure layers. Pure tin is sputtered from tin sputter target onto the exposed brazing surfaces of the cathode cap and the anode. The insulating shell is placed in a vacuum chamber of deposition applicator, which deposits an active metal onto the shell brazing surface. In a brazing oven, the anode is placed within insulating shell such that the anode conical brazing surface and the shell conical brazing surface are contacting and aligned with each other. During brazing, the cathode is brought into contact with the insulating shell. The sealed emitters are placed in a sputtering machine's vacuum chamber. A metal is sputtered from a sputtering target to form a metal layer on the exterior of insulating shell.

    摘要： A system for treating a vascular condition includes a therapeutic agent eluting medical device having a multilayered coating comprising microspheres of variable wall thicknesses. The wall thicknesses and the composition of the microspheres provide a controlled delivery system for one or more therapeutic agents. Another embodiment of the invention includes a method of treating a vascular condition by placing a stent at the treatment site and delivering one or more therapeutic agents from a coating on at least a portion of the stent surface. The coating comprises microspheres of variable wall thicknesses and optionally, an agent that modulates the rate of degradation of the microspheres.
