Title: A precursor stent gasket for receiving bilateral grafts having controlled contralateral guidewire access
Inventor: LETENDRE ROBERT P
IPC: A61F2/06
Filed: 2000-09-22
Abstract: In accordance with the present invention there is provided a precursor stent for implantation within the body of a patient, particularly for treating abdominal aortic aneurysms. The stent is designed to receive a pair of grafts placed side by side within the interior of the stent. The stent includes a substantially cylindrical and expandable member having a proximal end, a distal end, a longitudinal axis extending therebetween and an interior. The stent further includes an occlusive member attached to the expandable member. The occlusive member at least partially occludes a passageway or stent lumen which extends through the interior of the expandable member extending between its distal end and proximal end. The occlusive member has an opening extending therethrough designed to receive a guidewire for one of the grafts. Therefore, when the guidewire for the other graft is introduced, after deployment of the stent within a body, it will go through the portion of the interior not covered by the occlusive member. This helps to ensure proper side by side placement of the two grafts.

Title: Lading tie anchor system
Inventor: KAMPF MARK
IPC: B60P7/08
Filed: 2000-11-17
Abstract: A lading tie anchor system for railway box cars which uses lading ties comprising straps of woven webbing with a hook on one end in place of lading ties in the form of one-time useable steel strapping. The new system makes use of the lading tie anchors already installed in many box cars as well as those installed in newly built box cars. In addition to the novel lading ties a slack take-up and tension buckle is used to join the otherwise free or unanchored ends of each pair of lading ties. Preferably the buckles have a handle-crankable ratchet on one end to which the unanchored end of one of the installed ties is adjustably attached while the unanchored end of the other lading tie is threaded over a pair of take-up rollers mounted on the opposite end of the buckle in such a way that this second lading tie can be manually drawn taut.      Thereafter the ratchet is operated to remove any remaining slack in the lading ties and then apply the desired tension thereon. If the pairs of the lading ties are to be re-used in the same box car, web support clips may be inserted in the lading tie anchors located in the doorway posts and used to neatly support the free ends of the lading ties off the car floor and ready for re-use.

Inventor: FICE MARTYN
IPC: H04L12/56
Filed: 2000-12-12
Abstract: A method of reading and updating a packet header of an optical packet for transmission over an optical network involves dividing the input signal into two paths. The signal in one path (46) is converted into an electrical signal and the header information is read. The data stored in the packet header is removed optically in the other path (44) by constraining the packet header signal to have a constant amplitude. Updated header information is used to modify the constant amplitude signal using a modulator (60). An apparatus is provided for implementing the method. The header is thus read in the electrical domain, but it is updated optically.
