Publication number: 20180318081Abstract: According to one representative embodiment, a method of treating aortic insufficiency comprises delivering a support structure to a position around the leaflets of a native heart valve. An expandable prosthetic heart valve can be advanced into the native heart valve and into the interior of the annular body. The prosthetic heart valve can be expanded into contact with the leaflets of the native valve, thereby causing the leaflets of the native valve to be frictionally secured between an inner surface of the annular body and an outer surface of the prosthetic heart valve. A delivery apparatus for delivering the support structure can include a first shaft that is allowed to move in a proximal direction relative to a second shaft, when the second shaft foreshortens as a result of an adjustment mechanism being actuated to increase the curvature of the second shaft.Type: ApplicationFiled: July 6, 2018Publication date: November 8, 2018Inventors: Glen T. Rabito, Dustin P. Armer, Emil Karapetian

Publication number: 20180116790Abstract: Methods are described herein for delivering a replacement mitral valve to a native mitral valve location. In one method, ventricular anchors of the replacement mitral valve are released and allowed to reverse orientation while positioned in the left atrium of a human heart. After reversing orientation, the ventricular anchors extend in a generally proximal direction. The ventricular anchors can then be advanced through the mitral annulus into the left ventricle and then moved back toward the left atrium to capture native mitral valve leaflets between the main body and the ventricular anchors of the replacement mitral valve. In one modification, the ventricular anchors are allowed to reverse orientation at a level adjacent the mitral annulus. The implantation methods described herein are preferably performed via a transseptal delivery approach or a transapical delivery approach.Type: ApplicationFiled: October 30, 2017Publication date: May 3, 2018Applicant: Edwards Lifesciences CorporationInventors: J. Brent Ratz, Glen T. Rabito

Publication number: 20180055629Abstract: A replacement mitral valve prosthesis includes a support structure and a valve body having three flexible leaflets. The support structure preferably includes an internal valve frame and an external sealing frame. The valve frame supports the flexible leaflets. The sealing frame is adapted to conform to the shape of the native mitral valve annulus. The sealing frame may be coupled to an inlet end of the valve frame, an outlet end of the valve frame, or both. A plurality of anchors are coupled to the outlet end of the valve frame. The anchors extend radially outwardly for placement behind native leaflets. The prosthesis preferably includes a skirt disposed along an exterior of the external sealing frame. The prosthesis is collapsible for delivery into the heart via a delivery catheter. The prosthesis is configured to self-expand for deployment in the heart when released from the delivery catheter.Type: ApplicationFiled: August 25, 2017Publication date: March 1, 2018Applicant: Edwards Lifesciences CorporationInventors: Travis Zenyo Oba, Matthew A.

Publication number: 20170367821Abstract: Embodiments of a crimping device for crimping a radially expandable and compressible prosthetic valve are disclosed. A crimping device can comprise a housing configured to receive a prosthetic valve in a radially expanded state. The housing member can include a funnel segment and an outlet in communication with the funnel segment. The crimping device can further comprise an actuator rotatably coupled to the housing, wherein rotation of the actuator relative to the housing causes the prosthetic valve to move axially through the funnel segment such that at least a portion of the prosthetic valve compresses radially by engagement with the funnel segment and exits the crimping device via the outlet.Type: ApplicationFiled: April 14, 2017Publication date: December 28, 2017Applicant: Edwards Lifesciences CorporationInventors: David Robert Landon, Glen T.

Patent number: 9795302Abstract: Implementations of the tissue illumination systems, devices, and methods disclosed herein take advantage of the translucent nature of tissue to reveal properties by light transmission, for example, tissue type, tissue transition locations, underlying structures, and the like, that are not easily distinguished by reflected light. Illuminating a back-side of a translucent tissue permits a user to distinguish between different types of tissue, tissue transition locations, and/or structures that are difficult or impossible to discern under overhead or front-side illumination. Implementations include a light source that is positionable behind a tissue or disposable within a body cavity or duct, for example, within a heart ventricle.Type: GrantFiled: November 21, 2014Date of Patent: October 24, 2017Assignee: Edwards Lifesciences CorporationInventors: Stanton J.

A sealing system includes an elongate tubular support for delivery to an anatomical opening to be sealed, a cover of bio-compatible material covering a distal portion of the tubular support, and an anchor assembly, the anchor assembly being designed to secure the cover material to the opening. The anchor assembly can include a plurality of distal anchors and a plurality of proximal anchors, a button, ring or donut, and/or a C-clip. In some embodiments, the system further comprises a closure member for closing off an end of the cover material after removal of the tubular support.Type: GrantFiled: July 25, 2014Date of Patent: August 8, 2017Assignee: Edwards Lifesciences CardiAQ LLCInventors: Arshad Quadri, J.

Patent number: 9326853Abstract: 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: July 22, 2011Date of Patent: May 3, 2016Assignee: Edwards Lifesciences CorporationInventors: Christopher Olson, Glen T.
