Abstract
Generally, the present invention provides a device for insertion into a body and delivery of x-ray radiation, and a method for fabricating such a device. The device includes a connector, the vacuum housing, an anode and a cathode having a granular surface and being composed of a material that allows it to act as a getter. The cathode may also contain diamond material in one embodiment.
Claims18
A device suitable for insertion into a body and for delivery of x-ray radiation, comprising:
- a connector, including a proximal and a distal portion;
- a vacuum housing coupled to the distal portion of the connector;
- an anode disposed within the vacuum housing;
- and
- a cathode disposed within the vacuum housing and having a granular surface, the cathode being operative with the anode and the connector to produce the x-ray radiation, the cathode being composed of a material that also allows it to act as a getter.
