Publication number: 20220354638Abstract: A prosthetic heart valve includes a collapsible stent and a valve assembly disposed within the stent. A first cuff is disposed adjacent the stent. A second cuff having a distal edge facing the outflow end of the stent is disposed about the stent radially outward of the first cuff and the stent. The stent may include a plurality of fingers each having a first end coupled to a corresponding cell of the stent and a free end adapted to extend radially outward of the corresponding cell. The distal edge of the second cuff may be coupled to the fingers at spaced locations around the circumference of the stent to position the distal edge radially outward from the corresponding cells at the spaced locations. Various stent struts may be tapered to reduce the stent circumference in the collapsed condition, and to improve the fatigue resistance and/or bendability of the stent.Type: ApplicationFiled: July 26, 2022Publication date: November 10, 2022Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Kristen T. Morin, Gary Erzberger, Brett Allen Hillukka, Kristopher Henry Vietmeier, Kenneth L. Kelly

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

Patent number: 10182911Abstract: A clip for use during the loading of a prosthetic heart valve into a delivery device having an operating handle, a catheter assembly having a compartment for receiving the prosthetic heart valve, and an outer shaft joining the catheter assembly to the operating handle. The clip includes a first receiver coupleable to the operating handle of the delivery device and a second receiver coupleable to the outer shaft of the delivery device. The first and second receivers may be arranged orthogonally to one another so that in use the clip orients the catheter assembly substantially orthogonally to the operating handle.Type: GrantFiled: June 4, 2014Date of Patent: January 22, 2019Assignee: St. Jude Medical, Cardiology Division, Inc.Inventor: Brett Allen Hillukka

Patent number: 10039642Abstract: An assembly for collapsing a self-expanding prosthetic heart valve includes a compression member, a support member and a constricting member. The compression member has a tapered wall between its first open end and its second open end, the tapered wall defining an open space adapted to receive the valve. The support member has a base and a recess adapted to receive an end of the valve. The support member and the compression member are movable toward one another to compress the valve and push it through a relatively small aperture in the second open end of the compression member. The second end of the constricting member is sized to receive the compressed valve from the second open end of the compression member for loading into a delivery device.Type: GrantFiled: March 31, 2017Date of Patent: August 7, 2018Assignee: St. Jude Medical, Cardiology Division, Inc.Inventor: Brett Allen Hillukka
