Patent number: 11969344Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support structure and an expandable prosthetic valve are advanced through the aortic arch of a patient using a delivery system. The support structure is delivered to a position on or adjacent to the surface of the outflow side of the aortic valve (the support structure defining a support-structure interior). The expandable prosthetic valve is delivered into the aortic valve and into the support-structure interior. The expandable prosthetic heart valve is expanded while the expandable prosthetic heart valve is in the support-structure interior and while the support structure is at the position on or adjacent to the surface of the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the support structure and the expanded prosthetic heart valve.Type: GrantFiled: December 9, 2019Date of Patent: April 30, 2024Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Christopher J. Olson, Glen T. Rabito, Dustin P. Armer, Minh T. Ma, Devin H. Marr, Cheng-Tung Huang, Hiroshi Okabe, Kevin M. Stewart, Alison S. Curtis, Philip P. Corso, Jr.

Patent number: 11902368Abstract: A method is provided for managing over-the-top delivery of content through a plurality of content delivery networks (CDN). The method provided works transparently with standard HTTP servers supporting an initial request for content from a client to a first preferred CDN. If the first CDN does not have the content, the method includes provisions for the first CDN to acquire the content from a second CDN, or for the client to request the content from a second CDN directly. A system is also specified for implementing a client and server infrastructure in accordance with the provisions of the method.Type: GrantFiled: January 22, 2021Date of Patent: February 13, 2024Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Kevin J. Ma, Raj Nair, Robert Hickey, Daniel Biagini, Chin-Cheng Wu

Publication number: 20230042354Abstract: A method is provided for managing key rotation (use of series of keys) and secure key distribution in over-the-top content delivery. The method provided supports supplying a first content encryption key to a content packaging engine for encryption of a first portion of a video stream. Once the first content encryption key has expired, a second content encryption key is provided to the content packaging engine for encryption of a second portion of a video stream. The method further provides for notification of client devices of imminent key changes, as well as support for secure retrieval of new keys by client devices. A system is also specified for implementing a client and server infrastructure in accordance with the provisions of the method.Type: ApplicationFiled: October 25, 2022Publication date: February 9, 2023Applicant: Ericsson ABInventors: Kevin J.
