Patent number: 9119716Abstract: Described herein are systems and methods from delivering prosthetic devices, such as prosthetic heart valves, through the body and into the heart for implantation therein. The prosthetic devices delivered with the delivery systems disclosed herein are, for example, radially expandable from a radially compressed state mounted on the delivery system to a radially expanded state for implantation using an inflatable balloon of the delivery system. Exemplary delivery routes through the body and into the heart include transfemoral routes, transapical routes, and transaortic routes, among others.Type: GrantFiled: July 26, 2012Date of Patent: September 1, 2015Assignee: Edwards Lifesciences CorporationInventors: Walter Lee, Mark Dehdashtian, Teodoro S.

Publication number: 20070031321Abstract: A process, composition and apparatus for the removal of impurities from corrosive gases, particularly halogen-containing gases, down to about 100 ppb concentration are described. The critical component is zirconia (ZrO2), which in a variety of physical forms is capable of dehydrating such gases. The zirconia can be in the form of a coating on a substrate, as a granular bulk material, or deposited within the pores of a porous body. The zirconia is retained in a simple container which is easily installed in a gas supply line, such as to a gas- or vapor-deposition manufacturing unit. The purification process can be operated for long periods of time in the presence of these gases. The invention provides final purification to gas streams intended for gas- or vapor-deposition formation of high purity electronic, prosthetic or similar products, and can be used in combination with a preliminary dehydration process or a solid particulate removal unit upstream.Type: ApplicationFiled: June 23, 2004Publication date: February 8, 2007Inventors: Daniel Alvarez, Daniel Lev, Jeffrey Spiegelman, Tram Nguyen, Russell Holmes

Publication number: 20070016580Abstract: The present invention provides a method and system of extracting information about references to entities from a plurality of electronic documents. In an exemplary embodiment, the method and system include (1) applying at least one document quality measure to each of the plurality of electronic documents, (2) recognizing the references to entities in the plurality of electronic documents, (3) using at least one reference quality measure for each of the references to entities, (4) computing at least one topical category associated with each of the references to entities, (5) finding at least one co-occurring term associated with each of the references to entities, and (6) characterizing each of the references to entities by at least one characteristic category.Type: ApplicationFiled: July 15, 2005Publication date: January 18, 2007Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: John Mann, Tram Nguyen, Carlton Niblack, Zengyan Zhang

Publication number: 20070011670Abstract: Setting parameter values are migrated through a new software upgrade. Each software version includes a version number. The version number of the new software is compared to a version number of the current software. The version number of the current software is determined by reading a version number parameter value-stored in a non-volatile random access memory (NVRAM). If the version number of the new software is higher than the version number of the current software, for each setting parameter value within a new map file, either a current setting parameter value stored in the NVRAM or a default value from the map file, is loaded into a temporary memory. The map file, corresponding to the current version number parameter value stored in the NVRAM, is used to associate the values in the NVRAM to their corresponding setting parameters. Once a value for each setting parameter is loaded into the temporary memory, the values from the temporary memory are then loaded into the NVRAM.Type: ApplicationFiled: July 27, 2006Publication date: January 11, 2007Inventors: Tram Nguyen, Donald Molaro

Publication number: 20060248456Abstract: The present invention provides a method and system of assigning a publication date for at least one electronic document, where the publication date includes the year that the document was published, the month that the document was published, and the day that the document was published. In an exemplary embodiment, the method and system include (1) recognizing the publication date in the document by regular expression pattern matching, (2) if the publication date is ambiguous, resolving the ambiguous publication date, and (3) validating the publication date. In an exemplary embodiment, the recognizing includes determining at least one candidate publication date from the document identifier of the document. In an exemplary embodiment, the recognizing includes determining the publication date from the textual content of the document. In an exemplary embodiment, the recognizing includes determining the publication date from the metadata of the document.Type: ApplicationFiled: May 2, 2005Publication date: November 2, 2006Applicant: IBM CORPORATIONInventors: Todd Bender, Keiko Kurita, Tram Nguyen, C.
