20090084386 | TUBAL LIGATION - A medical device or system may include an anchor capable of grasping tissue, rotating the tissue, and/or occluding a space in communication with the tissue. A method for occluding a space within a patient may include grasping tissue, rotating the tissue, and/or occluding a space in communication with the tissue. | 04-02-2009 |
20100322384 | ROTATING ANODE WITH HUB CONNECTED VIA SPOKES - One example embodiment includes an anode. The anode comprises an anode hub, an annular target and a plurality of spokes. The spokes connect the anode hub to the annular target. The spokes are configured to substantially mechanically and/or thermally isolate the anode hub from the annular target. | 12-23-2010 |
20110311028 | X-RAY TUBE ROTATING ANODE - An x-ray tube rotating anode. In one example embodiment, an x-ray tube rotating anode includes a hub configured to attach to a bearing assembly, rings positioned radially outward from the hub, bridges connecting the rings together, annular ring fins each attached to one of the rings, a focal track positioned radially outward from the annular ring fins, and annular focal track fins attached to the focal track. | 12-22-2011 |
20120106713 | ELECTRICALLY INSULATING X-RAY SHIELDING DEVICES IN AN X-RAY TUBE - Electrically insulating x-ray shielding devices in an x-ray tube. In one example embodiment, an x-ray tube includes an evacuated enclosure, a cathode and an anode at least partially positioned within the evacuated enclosure, and an electrically insulating x-ray shielding device proximate to the evacuated enclosure. The electrically insulating x-ray shielding device includes an oxide or nitride material having an atomic number from 57 to 74. | 05-03-2012 |
20140247921 | TILTABLE OR DEFLECTABLE ANODE X-RAY TUBE - A x-ray tube comprising an anode sealed to a flexible coupling. The flexible coupling can allow the anode to deflect or tilt in various directions to allow an electron beam to impinge upon various selected regions of an anode target. | 09-04-2014 |
20140254767 | CATHODE ASSEMBLY FOR A LONG THROW LENGTH X-RAY TUBE - Cathode assembly for a long throw length x-ray tube. In one example embodiment, a cathode assembly for an x-ray tube includes an electron emitter, an acceleration region, and a drift region. The electron emitter includes a curved emitting surface configured to emit an electron beam having a y-dimension that is greater than an x-dimension at the electron emitter. The acceleration region is defined adjacent to the electron emitter. The acceleration region is configured such that when the electron beam propagates within the acceleration region, the electron beam accelerates in a z-direction substantially normal to a midpoint of the curved emitting surface. The drift region is defined between the acceleration region and an anode. The drift region is configured such that the combined lengths of the drift region and the acceleration region are sufficient for the y-dimension to be less than the x-dimension at the anode. | 09-11-2014 |
20140314209 | MULTI-TARGET X-RAY TUBE WITH STATIONARY ELECTRON BEAM POSITION - A transmission x-ray tube comprising an end window hermetically sealed to a flexible coupling. The flexible coupling can allow the window to shift or tilt in one direction or another direction to allow an electron beam to impinge upon one region of the window or another region of the window. | 10-23-2014 |
20150016590 | Soft X-Ray Curtain Tube - An elongated x-ray tube that can emit a linear curtain of x-rays along its length. Methods of using an elongated curtain of x-rays. | 01-15-2015 |
