Publication number: 20210145448Abstract: A medical device including stabilizing wires that are selectively movable from a first and second position and a delivery system including the same are described herein. The medical device includes a device body and the stabilizing wires coupled thereto. Each stabilizing wire has a proximal and distal end. In the first position, at least a portion of the distal end extends radially outwardly from the device body, and in the second position, the distal end is retracted within the device body. Each stabilizing wire includes a linear portion at the proximal end, a hook portion at the distal end, and a ramp segment extending between the linear portion and the hook portion, including a ramp incline portion that extends at a first angle from the linear portion to a ramp apex, and a ramp decline portion that extends at a second angle from the hook portion to the ramp apex.Type: ApplicationFiled: November 13, 2020Publication date: May 20, 2021Inventors: Gregory Gabay, Kristen T. Morin, Andrey Samaray, Trevor Springer

Publication number: 20210077254Abstract: A prosthetic heart valve may include a collapsible and expandable stent, a cuff attached to an annulus section of the stent, and a plurality of leaflets attached to at least one of the cuff or the stent within an interior region of the stent. The stent may have a plurality of cells connected to one another in a plurality of annular rows around the stent. The leaflets together may have a coapted position occluding the interior region of the stent and an open position in which the interior region is not occluded. Each leaflet may include a flat mesh of braided wire material having a plurality of pores extending therethrough. The leaflets may be devoid of biological material at a time of implantation.Type: ApplicationFiled: September 16, 2020Publication date: March 18, 2021Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Caytlin Gale, Gary Erzberger, Kristen T.

Publication number: 20210068956Abstract: A delivery device is configured for aligning and stabilizing a prosthetic heart valve for deployment in a native heart valve annulus. The device includes a catheter assembly having an inner shaft around which a valve compartment is defined, an outer shaft assembled over the inner shaft and adapted to slide relative to the inner shaft, a distal sheath connected to a distal end of the outer shaft and slidable therewith, an outer tube assembled over the outer shaft, and an alignment and stabilization device having a collapsed condition and an expanded condition. The outer tube is adapted to slide relative to the outer shaft to selectively cover and uncover the alignment and stabilization device.Type: ApplicationFiled: July 16, 2020Publication date: March 11, 2021Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Caytlin Gale, Gary Erzberger, Kristen T. Morin, Trevor J. Springer, Jaron J. Olsoe, Kristopher Henry Vietmeier

Publication number: 20200368006Abstract: Combined embolic protection devices and prosthetic heart valve delivery devices useful for filtering emboli during a heart valve replacement procedure are described. The delivery devices may include a delivery sheath for housing the prosthetic heart valve in collapsed condition for delivery. The delivery devices may include one or more embolic protection filters received within the delivery device during the delivery of the prosthetic heart valve. The embolic protection filters may be deployed into an expanded or deployed condition prior to deploying the prosthetic heart valve. Any embolic debris entering the bloodstream during the prosthetic heart valve deployment may be trapped within, or deflected by, the deployed embolic filter(s) to reduce the risk of stroke.Type: ApplicationFiled: May 15, 2020Publication date: November 26, 2020Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Caytlin Gale, Gary Erzberger, Kristen T. Morin, Trevor J. Springer, Jaron J. Olsoe, Kristopher Henry Vietmeier, Michael Shane Morrissey, Daniel J. Klima

Publication number: 20200170792Abstract: A loading assembly for crimping and loading a prosthetic heart valve into a delivery device includes a loading base, a base funnel, and a compression member. The loading base has a support and a body extending from the support with a recess defined within the body. The recess is configured to receive a substantial portion of the annulus section of the heart valve in an at least partially collapsed condition. The base funnel is configured to be coupled to the loading base and to at least partially collapse the annulus section of the heart valve as it is inserted into the recess in the loading base. The compression member is configured to be coupled to the loading base with the heart valve inserted in the recess for further collapsing the heart valve and loading it into the delivery device.Type: ApplicationFiled: January 21, 2020Publication date: June 4, 2020Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Kristen T. Morin, Keith High, Ian Wright

Publication number: 20200069417Abstract: 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: November 6, 2019Publication date: March 5, 2020Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Kristen T. Morin, Gary Erzberger, Brett Allen Hillukka, Kristopher Henry Vietmeier, Kenneth L. Kelly

Publication number: 20190298968Abstract: A prosthetic heart valve for replacing a native valve includes a stent having a plurality of struts, an inflow end, an outflow end, a collapsed condition and an expanded condition. A valve assembly is disposed within the stent. A first cuff is annularly disposed adjacent the stent, and a second cuff is annularly disposed about the stent radially outward of the first cuff and radially outward of the stent. The second cuff is at least partly radiopaque and may assist in determining the relative position between the second cuff and a patient's anatomy using fluoroscopy during an implantation procedure.Type: ApplicationFiled: January 10, 2019Publication date: October 3, 2019Applicant: St. Jude Medical, Cardiology Division, Inc.Inventor: Kristen T.

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.
