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: 10639148Abstract: A prosthetic valve assembly for implantation in a patient's circulatory system includes a stent, a valve member coupled to the stent and defining a preferred landing zone relative to anatomical structures in the patient's circulatory system, and at least one marker positioned in a predetermined relationship relative to the landing zone of the valve member, the marker being visually distinguishable from the stent using an imaging technique. By observing the marker, the prosthetic valve assembly may be implanted in the patient so that certain ones of the anatomical structures lie within the landing zone.Type: GrantFiled: July 25, 2017Date of Patent: May 5, 2020Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Peter N. Braido, Gary W. Geiger, Thomas Mark Benson, Steven Frederick Anderl, Aditee Kurane

Patent number: 10433957Abstract: A prosthetic heart valve includes a collapsible stent extending from an inflow end to an outflow end, and a cuff having an inflow end an outflow end. The stent includes first and second circumferential rows of cells defined by first and second pluralities of struts, respectively. The second circumferential row is positioned closer to the outflow end of the stent than the first circumferential row. At least one cell in the second circumferential row includes by a first strut opposed to a fourth strut and a second strut opposed to a third strut. A bridging feature in at least one cell in the second circumferential row includes first and second supplemental struts extending across an intermediate portion of the cell. The outflow end of the cuff is coupled to the stent along the bridging feature.Type: GrantFiled: November 17, 2017Date of Patent: October 8, 2019Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Sounthara (OTT) Khouengboua, Thomas Mark Benson, Xue Mei Li

Patent number: 10390950Abstract: A delivery device for a collapsible prosthetic heart valve includes an inner shaft having a proximal end and a distal end, an outer shaft disposed around the inner shaft and longitudinally moveable relative to the inner shaft, and a distal sheath disposed about a portion of the inner shaft and forming a compartment with the inner shaft, the compartment being adapted to receive the prosthetic heart valve. At least one of the outer shaft or the distal sheath may have a pattern of cutouts formed therein, the pattern including at least one ring around a circumference of the at least one of the outer shaft or the distal sheath, the at least one ring having at least one of the cutouts.Type: GrantFiled: September 24, 2015Date of Patent: August 27, 2019Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Ralph Joseph Thomas, Sounthara Khouengboua, Thomas Mark Benson, Brett Allen Hillukka

Publication number: 20180353291Abstract: A collapsible and expandable stent extends in an axial direction from a proximal end to a distal end. The stent may include a plurality of first cells, each first cell having an open space defined by a first plurality of struts. The stent may further include a second cell nested in the open space of one of the first cells, the second cell being defined by a second plurality of struts. The stent may additionally include first and second connecting struts connecting the second cell to the one first cell. The second cell may be configured to pivot about the first and second connecting struts with respect to the one first cell. The pivoting may create a clearance space between the second cell and an outer perimeter of the stent in which portions of a native valve structure may be clamped.Type: ApplicationFiled: August 14, 2018Publication date: December 13, 2018Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Thomas Mark Benson, Tracee Eidenschink

Patent number: 10085834Abstract: A collapsible and expandable stent (320) extends in an axial direction from a proximal end to a distal end. The stent may include a plurality of first cells (324), each first cell having an open space defined by a first plurality of struts (322). The stent may further include a second cell (330) nested in the open space of one of the first cells, the second cell being defined by a second plurality of struts (330a-d). The stent may additionally include first and second connecting struts (332, 334) connecting the second cell to the one first cell. The second cell may be configured to pivot about the first and second connecting struts with respect to the one first cell. The pivoting may create a clearance space between the second cell and an outer perimeter of the stent in which portions of a native valve structure may be clamped.Type: GrantFiled: March 13, 2015Date of Patent: October 2, 2018Assignee: St. Jude Medical, Cardiology Divsion, Inc.Inventors: Thomas Mark Benson, Tracee Eidenschink
