Patent number: 8353954Abstract: A prosthetic heart valve includes an annular stent having annularly spaced commissure portions. The tips of the commissure portions are preferably covered with fabric, and then additional fabric covers that fabric and the remainder of the stent, both inside and out (possibly also including a sewing ring insert at or near the base or inflow edge). The fabric is then covered by a layer of tissue, again both inside and out. A single sheet of additional tissue is mounted around the outside of the previously assembled components. This additional tissue forms the leaflet portions of the valve. The leaflet portions of the additional tissue are shaped by contact with a shaped mandrel, and the tissue of the structure is subjected to fixation (e.g., cross-linking) to produce a completed valve.Type: GrantFiled: December 19, 2007Date of Patent: January 15, 2013Assignee: St. Jude Medical, Inc.Inventors: Chad Cai, Peter Nicholas Braido, Bob Allan, Paul Edward Ashworth, Steve Kruse

Patent number: 7389874Abstract: Systems and methods for supporting a replacement heart valve are presented herein. A bioprosthesis may be stored in a storage container by suspending the bioprosthesis from a support structure. The volume of storage solution may be reduced by using a lid with a boss extending therefrom to displace some of the volume of the storage container. The support structure may rest on the base of the storage container. Additionally, there may be a holder attached to the bioprosthesis above the support structure. The holder-bioprosthesis-support structure may be constrained between the lid and base of the storage container.Type: GrantFiled: July 18, 2005Date of Patent: June 24, 2008Assignee: St. Jude Medical, Inc.Inventors: Matthew Quest, Bob Allan

Patent number: 7338484Abstract: Improved sizers and markers include a cylindrical section and a handle extending from the cylindrical section. The cylindrical section has a diameter approximately equal to the diameter of an aortic heart valve prosthesis. The cylindrical section can include a marking element configured to mark tissue at fixed positions relative to the cylindrical section. Marking can be performed with a variety of techniques.Type: GrantFiled: May 15, 2003Date of Patent: March 4, 2008Assignee: St. Jude Medical, Inc.Inventors: Thomas G. Schoon, M.

Patent number: 6176877Abstract: A prosthetic heart valve for implantation in a heart includes an outer orifice ring for coupling to a tissue annulus of a heart. An inner orifice ring includes at least one leaflet occluder carried in a lumen of the inner orifice ring which is movable between an open position, which allows blood flow through the lumen, and a closed position which blocks blood flow through the lumen. The inner orifice ring is adapted to be coupled to the outer orifice ring after the outer orifice ring has been attached to the tissue annulus.Type: GrantFiled: April 20, 1998Date of Patent: January 23, 2001Assignee: St. Jude Medical, Inc.Inventors: Eric S. Buchanan, Bob Allan, Michael J. Girard, William R. Holmberg, Kimberly A. Anderson

Patent number: 5876436Abstract: The invention provides a sewing cuff assembly for mounting to the body of a heart valve prosthesis. The sewing cuff assembly comprises a resiliently deformed spring for exerting a force directed toward the orifice structure. When a torque is applied to the valve, the force results in a rotation-resisting torque sufficient to resist rotation during normal operation of the valve after implantation but low enough to permit assisted rotation, as during surgery.Type: GrantFiled: February 13, 1997Date of Patent: March 2, 1999Assignee: St. Jude Medical, Inc.Inventors: Guy P. Vanney, Michael J. Girard, William R. Kramlinger, Jonas A. Runquist, Kimberly A. Anderson, Scott D. Moore, Bob Allan, James E. Graf

Patent number: 5788689Abstract: A prosthetic heart valve rotator tool operates in the small chest cavity available to the surgeon, having parts that can be easily assembled and disassembled, allowing it to be cleaned and sterilized for repeated use.Type: GrantFiled: January 31, 1996Date of Patent: August 4, 1998Assignee: St. Jude Medical, Inc.Inventors: Bob Allan, Kimberly A. Anderson, William R. Holmberg, Kurt D. Krueger, Michael J. Girard, Thomas G. Schoon, Gary G. Rushmeyer
