Patent number: 9387072Abstract: A prosthetic heart valve includes a stent having an expanded condition and a collapsed condition. The stent includes a plurality of distal cells, a plurality of proximal cells, a plurality of support struts coupling the proximal cells to the distal cells, and at least one support post connected to a plurality of proximal cells. The proximal cells are longitudinally spaced apart from the distal cells. Various strut configurations and connections of the struts to the proximal cells and of the proximal cells to the support post improve stent flexibility and reduce stress in the valve leaflets.Type: GrantFiled: June 13, 2014Date of Patent: July 12, 2016Assignee: St. Jude Medical, Inc.Inventors: Peter N. Braido, Yousef F. Alkhatib, Thomas M. Benson, Aaron J. Chalekian, Ott Khouengboua, Julia A. Neuman

Patent number: 9226820Abstract: A stent (10) for use in a prosthetic heart valve has an annulus section (12) adapted for placement within the ? leaflets and annulus of the native heart valve. The annulus section has latch members (50) adapted to engage the leaflets of the native heart valve when prosthetic valve is implanted in the native valve. The latch members may hold the leaflets in engagement with the annulus section, and help to retain the prosthetic valve in position. The annulus section may have a non-circular cross-sectional shape.Type: GrantFiled: July 15, 2009Date of Patent: January 5, 2016Assignee: St. Jude Medical, Inc.Inventors: Peter N. Braido, Julia A. Neuman, Thomas M. Benson

Publication number: 20150282932Abstract: A prosthetic heart valve includes a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end and an aortic section adjacent the distal end. The stent is formed of a plurality of struts. A cuff is coupled to the stent. The cuff has one or more features configured to reduce abrasion and/or perivalvular leakage.Type: ApplicationFiled: June 22, 2015Publication date: October 8, 2015Applicant: ST. JUDE MEDICAL, CARDIOLOGY DIVISION, INC.Inventors: Julia A. Neuman, Peter N. Braido, Ramji T. Venkatasubramanian, Aditee Kurane, Mina S. Fahim, Jaishankar Kutty

Patent number: 8808356Abstract: A prosthetic heart valve is provided with a cuff having features which promote sealing with the native tissues even where the native tissues are irregular. The cuff may include a portion adapted to bear on the LVOT when the valve is implanted in a native aortic valve. The valve may include elements for biasing the cuff outwardly with respect to the stent body when the stent body is in an expanded condition. The cuff may have portions of different thickness distributed around the circumference of the valve in a pattern matching the shape of the opening defined by the native tissue. All or part of the cuff may be movable relative to the stent during implantation.Type: GrantFiled: July 15, 2009Date of Patent: August 19, 2014Assignee: St. Jude Medical, Inc.Inventors: Peter N. Braido, Paul E. Ashworth, Julia A. Neuman

Patent number: 8425593Abstract: Prosthetic heart valves, which are collapsible to a relatively small circumferential size for less invasive delivery into a patient and which then re-expand to operating size at an implant site in the patient, include a collapsible/expandable stent-like supporting structure and various components of flexible, sheet-like material that are attached to the supporting structure. For example, these sheet-like other components may include prosthetic valve leaflets, layers of buffering material, cuff material, etc. Improved structures and techniques are provided for securing such other components to the stent-like supporting structure of the valve.Type: GrantFiled: September 26, 2008Date of Patent: April 23, 2013Assignee: St. Jude Medical, Inc.Inventors: Peter N. Braido, Andrea L. McCarthy, Rubem L. Figueiredo, Julia A. Neuman

Publication number: 20110098802Abstract: A prosthetic heart valve is provided with a cuff (85, 285, 400) having features which promote sealing with the native tissues even where the native tissues are irregular. The cuff may include a portion (90) adapted to bear native aortic valve. The valve may include elements (210, 211, 230, 252, 253) for biasing the cuff outwardly with respect to the stent body when the stent body is in an expanded condition. The cuff may have portions of different thickness (280) distributed around the circumference of the valve in a pattern matching the shape of the opening defined by the native tissue. All or part (402) of the cuff may be movable relative to the stent during implantation.Type: ApplicationFiled: July 15, 2009Publication date: April 28, 2011Inventors: Peter N. Braido, Paul E.
