Patent number: 10821806Abstract: This disclosure relates to a valve assembly for a motor vehicle, such as a pressure relief valve, and a method of using the same. The valve assembly includes a flap moveable to between an open position and a closed position. The valve assembly further includes a pair of shape memory-alloy (SMA) wires configured to move the flap between the open and closed positions. Specifically, the valve includes a first shape-memory alloy wire configured to rebound to a first rebound shape to urge the flap to the open position, and a second shape-memory alloy wire configured to rebound to a second rebound shape to urge the flap to the closed position.Type: GrantFiled: July 31, 2017Date of Patent: November 3, 2020Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Eric J. MacLean, David Arthur Wade

Patent number: 10813746Abstract: The invention relates to a prosthetic valve (1) for regulating fluid flow between an upstream side (4) and a downstream side (5) and being operable between an open status and a closed status. The prosthetic valve comprises: —an orifice (2) arranged in a surrounding member (3) and extending between the upstream side (4) and the downstream side (5) wherein in the open status of the prosthetic valve (1) the fluid flow through the orifice is maximally enabled and wherein in the closed status of the prosthetic valve the fluid flow through the orifice in a restriction direction (21) from the downstream side (5) to the upstream side (4) is restricted; and—a leaflet (6) arranged in the orifice and being operable between an open status corresponding to the open status of the prosthetic valve and a closed status corresponding to the closed status of the prosthetic valve.Type: GrantFiled: July 12, 2017Date of Patent: October 27, 2020Assignee: Medtronic, Inc.Inventors: Richard Cornelussen, Asimina Glynou, Pascalle Reiters, Robert Vestberg, Ulrich Wolfhard

Patent number: 10786355Abstract: A method of treating a mitral valve without open-heart surgery is disclosed. An expandable prosthesis comprises an anchoring portion and an occluding member coupled to the anchoring portion. The prosthesis is loaded into a distal end of a delivery catheter and advanced through a femoral vein and through a pre-made puncture in an atrial septum. The occluding member is then positioned in the mitral valve and the anchoring portion is positioned in the left atrium for maintaining the occluding member between the leaflets of the mitral valve. After deployment, the occluding member prevents blood from flowing from the left ventricle to the left atrium during systole.Type: GrantFiled: January 9, 2018Date of Patent: September 29, 2020Assignee: Edwards Lifesciences AGInventors: Avraham Zakai, David Mishaly, Dan Rottenberg, David Alon

Patent number: 10772723Abstract: A prosthetic heart valve can include an expandable support stent, a valve assembly, and a connecting membrane. The support stent can have first and second end portions and can be configured to be radially expandable from a first configuration to a second configuration. The valve assembly can have an inlet portion, an outlet portion, and a plurality of leaflets, and the valve assembly can be supported in the support stent. The connecting membrane can be disposed radially between the support stent and the valve assembly, wherein the support stent and the valve assembly can be connected to the connecting membrane.Type: GrantFiled: August 17, 2017Date of Patent: September 15, 2020Assignee: Edwards Lifesciences CorporationInventor: Stanton J. Rowe

Patent number: 10751180Abstract: A prosthetic valve coaptation assist device (100) includes an anchor (101) and a single valve assist leaflet (102). The anchor may be a supporting ring frame, brace or arc structure and will usually be radially self-expandable so that it can expand against surrounding tissue. The valve assist leaflet may be made of pericardium or other biological or artificial material and is shaped like the native target valve leaflet. The valve assist leaflet is typically sized larger than the target leaflet so that after implantation a significant overlap of the device body occurs.Type: GrantFiled: June 13, 2014Date of Patent: August 25, 2020Assignee: MTEX Cardio AGInventor: Jury Schewel
