Patent number: 9452046Abstract: A method for replacing a diseased aortic valve includes selecting a prosthetic heart valve based on a measurement of a patient's aortic annulus, the prosthetic heart valve stored in a storage container while in an expanded configuration. The preservative solution is drained from the storage container and the prosthetic heart valve is removed. The prosthetic heart valve is compressed to a contracted configuration and advanced through a patient's vasculature along a distal end portion of a catheter system. The prosthetic heart valve is positioned within the diseased aortic valve and re-expanded to an initial expanded configuration. A deployment mechanism is actuated via an operating handle to further expand the prosthetic heart valve into secure engagement with surrounding tissue until lockout features on the prosthetic heart valve secure the prosthetic heart valve in a final expanded configuration.Type: GrantFiled: January 13, 2012Date of Patent: September 27, 2016Assignee: Edwards Lifesciences CorporationInventors: Jibin Yang, Matthew L. Pease, Scott H. Heneveld, Brandon G. Walsh

Publication number: 20160151152Abstract: A system for delivering and deploying a self-expandable heart valve to a site of implantation such as the aortic annulus includes a deployment mechanism that engages the valve and regulates the rate of expansion of both the proximal and distal ends thereof. The heart valve may be a rolled-type valve and the deployment mechanism may include a plurality of distal fingers and a plurality of proximal fingers that engage the outer layer of the heart valve. Controlled radial movement of the fingers regulates the unwinding of the rolled heart valve. The deployment mechanism may include an umbrella structure that forces the rolled valve outward into its fully expanded configuration. Alternatively, a gear shaft that engages one or more gear tracks on the valve may be utilized to regulate expansion of the valve.Type: ApplicationFiled: February 5, 2016Publication date: June 2, 2016Applicant: Edwards Lifesciences CorporationInventors: Jibin Yang, Scott H.

Patent number: 9350084Abstract: Electromagnetic (EM) feeds can illuminate a standard primary reflective antenna with a plurality of feed beams each having a different orbital angular momentum (OAM) or polarization. The reflective antenna, which can be a non-OAM antenna, can reflect the feed beams and thereby produce a composite OAM transmission comprising each of the feed beams. A non-OAM primary antenna can thus transmit a plurality of OAM feed beams as a composite OAM transmission.Type: GrantFiled: November 12, 2013Date of Patent: May 24, 2016Assignee: L-3 Communications Corp.Inventors: Johnny M.

Patent number: 9168136Abstract: A method for delivering and implanting a prosthetic heart valve in a native aortic valve is provided. The method comprises advancing the prosthetic heart valve through a patient's vasculature while the prosthetic heart valve is coupled to a mechanical deployment mechanism along a distal end portion of a catheter shaft. The prosthetic heart valve is permitted to self-expand from a contracted configuration to an initial expanded configuration. The mechanical deployment mechanism is then actuated via an operating handle to further expand the prosthetic heart valve to a fully expanded configuration while equilibrating the rate of the expansion of the proximal and distal ends of the prosthetic heart valve. The prosthetic heart valve is locked in the fully expanded configuration via a mechanical locking device disposed on the prosthetic heart valve.Type: GrantFiled: May 19, 2015Date of Patent: October 27, 2015Assignee: Edwards Lifesciences CorporationInventors: Jibin Yang, Scott H.

Patent number: 9031151Abstract: A transmit antenna or antennas can be configured to transmit a composite orbital angular momentum (OAM) radio frequency (RF) beam comprising a plurality of individual OAM RF signals each having a different OAM mode. An array of antennas for receiving and resolving the composite OAM beam into the individual OAM signals can be located entirely within a relatively small sector of a far field pattern of the composite OAM beam. A processing module connected to the antennas of the receive array can resolve the composite OAM beam into its individual OAM signals using angular resolution. The transmit antenna can transmit the individual OAM signals—and thus the composite OAM beam—as full OAM signals or partial-beam OAM signals.Type: GrantFiled: May 7, 2014Date of Patent: May 12, 2015Assignee: L-3 Communications, Corp.Inventors: Johnny M.
