Patent number: 11246706Abstract: A prosthetic heart valve may include a stent having an inflow end, an outflow end, a collapsed condition, and an expanded condition. The prosthetic valve may also include a collapsible and expandable valve assembly disposed within the stent and having a plurality of leaflets. The prosthetic valve and/or stent may include features to anchor the prosthetic valve to a native valve annulus and to seal the prosthetic valve with respect to the native valve annulus, such as planar and/or nonplanar annular sealing members coupled to ends of the stent. The stent may include one or more circumferential rows of anchor members or hooks extending radially outwardly from the stent. These hooks may be configured to extend in a particular direction when the stent is in the collapsed condition to facilitate resheathing of the stent if, upon deployment, a user determines the prosthetic heart valve is not positioned optimally.Type: GrantFiled: April 23, 2019Date of Patent: February 15, 2022Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Theodore Paul Dale, Andrea N. Para, Gaurav Satam, Jason Diedering, Thomas Mark Benson, Saravana B. Kumar

Patent number: 11007054Abstract: A prosthetic heart valve for replacing a native valve includes a collapsible and expandable stent extending between a proximal end and a distal end. The stent includes an annulus section adjacent the proximal end and having a first diameter, a plurality of first struts forming cells, and a plurality of second struts connected to the annulus section and forming a plurality of deflecting cells expandable to define a second diameter larger than the first diameter. A valve assembly is disposed within the stent and a cuff is coupled to the stent and covers the plurality of deflecting cells.Type: GrantFiled: August 23, 2018Date of Patent: May 18, 2021Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Peter N. Braido, Kent J. Smith, Andrea L. McCarthy, Andrea N. Para, Sounthara Khouengboua, Thomas M. Benson, Saravana B. Kumar, Bruce Moseman, Gaurav Satam

Patent number: 10299926Abstract: A prosthetic heart valve includes a collapsible and expandable stent extending from an inflow end to an outflow end and a plurality of prosthetic valve leaflets coupled to the stent. The prosthetic heart valve may also include a sealing ring coupled to the inflow end of the stent, the sealing ring comprising a tube extending circumferentially around the inflow end of the stent. The tube may be formed from a wire coiled into a repeating shape, such as a rectangle or a diamond, so that the tube is collapsible. A covering may at least partially surround the tube. The sealing ring may include a first filler positioned within the tube and/or a second filler positioned between the tube and the covering.Type: GrantFiled: April 27, 2018Date of Patent: May 28, 2019Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Kristen T. Morin, Andrea N. Para, Peter N. Braido, Sounthara Khouengboua, Thomas M. Benson, Saravana B. Kumar, Bruce Moseman, Gaurav Satam

Publication number: 20190000617Abstract: A prosthetic heart valve for replacing a native valve includes a collapsible and expandable stent extending between a proximal end and a distal end. The stent includes an annulus section adjacent the proximal end and having a first diameter, a plurality of first struts forming cells, and a plurality of second struts connected to the annulus section and forming a plurality of deflecting cells expandable to define a second diameter larger than the first diameter. A valve assembly is disposed within the stent and a cuff is coupled to the stent and covers the plurality of deflecting cells.Type: ApplicationFiled: August 23, 2018Publication date: January 3, 2019Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Peter N. Braido, Kent J. Smith, Andrea L. McCarthy, Andrea N. Para, Sounthara Khouengboua, Thomas M. Benson, Saravana B. Kumar, Bruce Moseman, Gaurav Satam
