Title: Self-expandable stent and stent-graft and method of using them
Inventor: LAU LILIP
IPC: A61F2/92
Filed: 1995-04-03
Granted: 2000-03-07
Abstract: The device is a foldable stent (122) or stent-graft (370) which may be delivered with (or on) a catheter or via surgical or other suitable techniques. The device is then expanded or unfolded. The expandable stent structure preferably utilizes at least one torsional member (100) generally aligned with the longitudinal axis of the stent (122). The stent (122) preferably has an undulating shape. It may be helically deployed to form the generally cylindrical shape eventually deployed as the stent (122) or it may be formed of one or more rings (302). The structure desirably is aligned to allow those undulating shapes in adjacent rings (322) or turns of the helix to be in phase. The adjacent undulating shapes may be held in that phased relationship using a flexible linkage (324) often made of a polymeric material. The stent (122) is self-expanding, kink-resistant, easily bent along its longitudinal axis, does not change its length during that expansion, and is able to provide collapsible support for otherwise frangible graft material. The graft component (134) cooperating with the stent (122) is tubular and may be a biocompatible polymeric or collagenous material or combinations of the two which may, if desired, be reinfored with fibers.

Abstract: A device and method for testing a telephone circuit in which a caller takes advantage of available caller identification information to complete a ringback test, device is accessed by a caller who may not be aware of the telephone number from which he is calling when the caller completes a call to a telephone number assigned to the device. As the caller is accessing the test device, the test device detects the caller identification available between the first and second rings to identify the caller's telephone number, and answers the call after the second ring. The test device presents the telephone number to the caller. The caller ID information may be display-formatted at the test device and provide a visual display.

Abstract: The Multimedia Message System of the present invention provides revenue allocation between disparate sender-receiver service providers on a per message basis for a sender, connected to a telcommunications network of one service provider, sending a message to a receiver, connected to a telcommunications network of another service provider. Each message has a "message stamp" associated with it which allows for distribution of revenue associated with that individual message among service providers involved for transmission of that message. A Clearinghouse is utilized to issue the message stamps and process revenue allocation for each service provider according to the message stamps. The stamp is added to each message by the clearinghouse to provide for revenue allocation between the originating (sender) and destination (receiver) service providers. Removal or canceling of the stamp is preformed by the destination unit that may additionally route the message to a mailbox (e.g., service node) or further destination service providers. The stamp revenue is shared by the message sender service provider, the stamp issuer, and message receiver service provider, the collector of the used/canceled stamp. The canceled stamp may be exchanged or redeemed between the service providers via their respective clearinghouses, for currency or additional stamps according to a predetermined revenue sharing arrangement between participating service providers.

Abstract: The invention relates to a method of processing seismic data (102, 104) on parallel processors (106, 108, 110), preferably on a massively parallel processor (MPP) (100). The input to the process is seismic data from one or more of a number of seismic lines (2). The end product of the invention is a DMO corrected, zero-offset seismic image of the subsurface. By repeating the method on different input offsets, the variation in reflection strength of a reflector as a function of the angle of incidence can be examined. The method includes a two stage parallelization. First, a parallelization over the incoming traces generates a suite of DMO-corrected partial images for each point on each incoming trace. Secondly, a parallelization over output locations accumulates and combines the partial images, and produces output traces.
