Publication number: 20210290378Abstract: Disclosed herein are embodiments of an expandable replacement heart valve prosthesis. The expandable replacement heart valve prosthesis can include a number of different features, such as an hourglass (or generally hourglass) shape in the fully expanded position, anchor stiffening features, and improved retraction/retention configurations. For example, certain struts on the prosthesis can have different thicknesses/widths than other struts to improve compressibility.Type: ApplicationFiled: June 9, 2021Publication date: September 23, 2021Applicant: Edwards Lifesciences CorporationInventors: Alexander H. Cooper, Juliet Laura Schwartz, Wendy Vo Pham, Hieu Minh Luong, Julio Cesar Sanchez, Matthew A. Peterson, J. Brent Ratz, Lisong Ai

Patent number: 11051934Abstract: A mitral valve prosthesis includes an hourglass shaped inner frame and a bulbous outer frame. A valve body having a plurality of leaflets is positioned within an interior region of the inner frame. The leaflets are shaped to substantially conform to an interior surface of the inner frame when the leaflets are in an open position. As a result, the gap between the leaflets and the inner frame is decreased, thereby reducing the likelihood of thrombus formation. Ventricular anchors are preferably provided along a distal end of the inner frame. The anchors extend proximally for placement behind native mitral valve leaflets. A fabric skirt may extend along an inner or outer surface of the outer frame. In preferred embodiments, the fabric skirt extends distally beyond a distal end of the outer frame and is adapted for forming a seal along the mitral valve annulus.Type: GrantFiled: February 26, 2019Date of Patent: July 6, 2021Assignee: Edwards Lifesciences CorporationInventors: Alexander H. Cooper, Juliet Laura Schwartz, Wendy Vo Pham, Hieu Minh Luong, Julio Cesar Sanchez, Matthew A. Peterson, J. Brent Ratz, Lisong Ai

Publication number: 20150354222Abstract: Techniques for warming building materials, such as shingles and siding, are provided. In various implementations, a cover is positioned over building materials and secured in place. The cover at least partially defines an interior space in which the building materials are located. The cover is then connected to a mechanical heating device. The mechanical heating device is activated to provide heat to an interior space. At least some of the building materials are removed from the interior space and used in a building project. In various implementations, the mechanical heating device is activated about twenty-four to forty-eight hours before the materials will be used.Type: ApplicationFiled: June 4, 2014Publication date: December 10, 2015Inventor: Cesar Sanchez
