Title: Endovascular graft for repairing abdominal aortic aneurysms
Inventor: KONSTANTINOS PAPAZOGLOU O
IPC: A61F2/848
Filed: 1998-04-09
Abstract: This is regarding a type of device aimed at a simpler, in relation to already existing techniques, endovascular positioning of a stent-graft in the abdominal aorta for the therapy of aneurysms up to the point of its bifurcation.  This device is comprised of a system of three cylinders: a "main" centrally placed and two "limbs" peripherally placed. Each of these cylinders has a central and a peripheral orifice. The cylinders are comprised of a cylindrical metallic skeleton which is self-expanding and made out of stainless steel or nitinol and which is externally covered with a cylinder made out of thin-layered PTFE, Dacron or some other elastic biocompatible material, refolded around the peripheral orifice of the skeleton of the main cylinder. These cylinders can be compressed into small diameter tubules and enter the vascular lumen.  After their insertion into the desired position, they expand, regaining their original diameter. The main cylinder is placed inside the aorta becoming more circular when it comes in contact with the healthy part of the aorta central to the aneurysm at the center of the orifice. The peripheral orifice of the main cylinder sits upon the expanded aortic bifurcation. The two limbs have a central orifice with a diameter equal to or approximately about 2 mm smaller than the diameter of the peripheral orifice of the main cylinder. The branching of the main cylinder is accomplished by the entrance of the main ends of the two limbs inside the peripheral end of the main cylinder. Both limbs are at the same height in such a manner that they compress each other at the center of the cylinder. Each limb exerts equal pressure, whereas equal pressure is also exerted on the internal surface of the main cylinder from their external surface and together they both occupy at the height of their orifices the entire perimeter of the main cylinder. Alternatively, as limbs (peripheral cylinders), tubes of different diameters and types of skeletons can be used.

Title: A compact side-fed dual reflector antenna system for providing adjacent, high gain antenna beams
Inventor: PEEBLES ANN L
IPC: H04B7/19
Filed: 1999-12-29
Abstract: An antenna system comprising a feed array, a subreflector and a main reflector which are oriented to define a side-fed dual reflector antenna geometry. The feed array is comprised of a plurality of separate feeds which are aligned on a predetermined contour. Each feed array is coupled to a feed network which acts to combine the illumination beams of clusters of a preselected number of feeds to produce a plurality of composite illumination beams. Each composite illumination beam is directed to be incident upon a separate preselected location on the subreflector which directs the composite illumination beams towards the main reflector. Each composite illumination beam is reflected by the main reflector in a preselected direction so that each composite illumination beam forms an antenna beam that impinges a predetermined coverage area on the Earth. Each antenna beam defines a separate coverage cell in the coverage area, wherein the position and orientation of the feeds, the subreflector and the main reflector provides antenna beams over a full Earth field of view coverage area where each antenna beam is approximately symmetrically shaped.
