Patent number: 11903825Abstract: A replacement heart valve has an expandable frame configured to engage a native valve annulus and a valve body mounted to the expandable frame. The valve body can have a plurality of valve leaflets configured to open to allow flow in a first direction and engage one another so as to close and prevent flow in a second direction, the second direction being opposite the first direction.Type: GrantFiled: July 28, 2020Date of Patent: February 20, 2024Assignee: Edwards Lifesciences CardiAQ LLCInventors: Arshad Quadri, J. Brent Ratz, Robrecht Michiels

Publication number: 20220313431Abstract: A heart valve prosthesis is provided having a self-expanding multi-level frame that supports a valve body comprising a skirt and plurality of coapting leaflets. The frame transitions between a contracted delivery configuration that enables percutaneous transluminal delivery, and an expanded deployed configuration having an asymmetric hourglass shape. The valve body skirt and leaflets are constructed so that the center of coaptation may be selected to reduce horizontal forces applied to the commissures of the valve, and to efficiently distribute and transmit forces along the leaflets and to the frame. Alternatively, the valve body may be used as a surgically implantable replacement valve prosthesis.Type: ApplicationFiled: June 19, 2022Publication date: October 6, 2022Inventors: Than Nguyen, Hung Nguyen, MyKim Nguyen, Stanley Komatsu, Robrecht Michiels

Patent number: 10779938Abstract: A method of treating a diseased native valve includes advancing a replacement heart valve to native valve annulus. The heart valve includes an expandable frame and a valve body. The frame is formed with a plurality of cells and the valve body is formed with a plurality of leaflets configured to allow blood flow in a first direction. The frame is expanded from a radially compacted configuration to an expanded configuration at the native valve annulus. The replacement heart valve also includes one or more openings covered by one or more flaps and blood is allowed to flow through the openings in the first direction.Type: GrantFiled: December 20, 2018Date of Patent: September 22, 2020Assignee: Edwards Lifesciences CardiAQ LLCInventors: Arshad Quadri, J.

Patent number: 10524901Abstract: A replacement heart valve can have an expandable frame configured to engage a native valve annulus. A valve body can be mounted onto the expandable frame to provide functionality similar to a natural valve. The valve body has an upstream end and a downstream end, and a diameter at the downstream end is greater than a diameter at the upstream end.Type: GrantFiled: April 28, 2017Date of Patent: January 7, 2020Assignee: Edwards Lifesciences CardiAQ LLCInventors: Arshad Quadri, J.

Patent number: 9480560Abstract: A method is disclosed of enhancing the securing of an intralumenal frame assembly to intralumenal tissue at an in situ target location. The method can comprise delivering an intralumenal frame assembly mounted on a delivery device to a treatment location. The intralumenal frame can be deployed to expand in situ so that anchors on the intralumenal frame atraumatically grasp intralumenal tissue at the target location. A radially inward force can be exerted on the frame assembly to cause the proximal and distal anchors to grasp more forcefully the intralumenal tissue.Type: GrantFiled: January 31, 2013Date of Patent: November 1, 2016Assignee: Edwards Lifesciences CardiAQ LLCInventors: Arshad Quadri, J.
