Publication number: 20170209264Abstract: A prosthetic apparatus for implantation in a native mitral valve includes a main body for placement within the native mitral annulus. The main body is compressible to a radially compressed state for delivery into the heart and is self-expandable from the compressed state to a radially expanded state for implantation. A valve structure is mounted within a lumen of the main body and preferably forms three leaflets made of pericardium. An atrial sealing member is disposed along an atrial portion of the main body and ventricular anchors are coupled to a ventricular portion of the main body. The atrial sealing member impedes the flow of blood between the main body and the native annulus. The ventricular anchors are positioned outside the main body for capturing native mitral valve leaflets between the main body and the ventricular anchors.Type: ApplicationFiled: March 10, 2017Publication date: July 27, 2017Applicant: Edwards Lifesciences CorporationInventors: Mark Chau, Marlowe E. Patterson, Seung-Beom Yi, Stephen C. Geist, Travis Zenyo Oba

Patent number: 9439763Abstract: Embodiments of prosthetic valves for implantation within a native mitral valve are provided. One embodiment of a prosthetic valve includes a radially compressible main body and a one-way valve member. In some cases, the prosthetic valves also include ventricular anchors and/or an atrial portion coupled to and disposed outside of the main body. Methods, devices, and systems for delivering such prosthetic valves to the native mitral valve and implanting them therein are also provided.Type: GrantFiled: February 3, 2014Date of Patent: September 13, 2016Assignee: Edwards Lifesciences CorporationInventors: Stephen C.

Patent number: 9433500Abstract: A prosthetic apparatus configured for implantation in the native mitral valve region of the heart includes a main body that is self-expandable from a compressed state to a radially expanded state. The prosthetic apparatus comprises at least one ventricular anchor coupled to the main body and disposed outside of the main body for capturing a native valve leaflet between the anchor and an outer surface of the main body. In one preferred method of implantation, the prosthetic apparatus is rotated within the native mitral valve region such that a portion of the anchor moves horizontally behind adjacent chordae for anchoring the prosthetic apparatus in the native mitral valve.Type: GrantFiled: July 16, 2015Date of Patent: September 6, 2016Assignee: Edwards Lifesciences CorporationInventors: Mark Chau, Marlowe E. Patterson, Seung-Beom Yi, Stephen C. Geist, Travis Oba

Publication number: 20160199184Abstract: A prosthetic valve assembly includes an annular frame having an inner radial surface, an outer radial surface, and defining an inner lumen. The prosthetic valve assembly further includes a leaflet assembly including at least one leaflet having an inner radial surface and an outer radial surface. The at least one leaflet is disposed at least partially within the inner lumen of the annular frame. The prosthetic valve assembly includes a crimping accessory device having a handle and at least one shielding member removably disposed between the outer radial surface of the at least one leaflet and the inner radial surface of the annular frame. The at least one shielding member is configured to reduce physical contact between the at least one leaflet and the inner radial surface of the annular frame.Type: ApplicationFiled: March 18, 2016Publication date: July 14, 2016Inventors: Minh T. Ma, Seung-Beom Yi, Ryan Silva

Publication number: 20150336150Abstract: Embodiments of an apparatus, and a method for crimping expandable stents or prosthetic valves having a radially expandable and compressible annular body and one or more protruding anchors extending from the body using the apparatus, where the apparatus comprise a housing, a plurality of circumferentially arranged nesting jaws, and an actuator configured to move the jaws radially inwardly to reduce the size of the crimping aperture, thereby radially compressing the annular body of the prosthetic valve or stent. In particular embodiments, a selected set of the jaws, each having a front side and a recessed portion in its front side adjacent to its inner end. The recessed portions of the selected jaws collectively are sized and shaped to receive the one or more anchors of the prosthetic valve when the annular body is positioned within the crimping aperture.Type: ApplicationFiled: May 8, 2015Publication date: November 26, 2015Applicant: Edwards Lifesciences CorporationInventors: Matthew A. Peterson, Robert C. Taft, Devin H. Marr, Minh T. Ma, Seung-Beom Yi, Ryan Silva
