Patent number: 10687938Abstract: Docking devices can be configured to be positioned at a native valve of a human heart to provide structural support for docking a prosthetic valve. The docking devices generally have coiled structures that define an inner space in which the prosthetic valve can be held. Some docking devices can be adjusted from a first wider configuration which facilitates easier advancement of the docking device around the valve anatomy, to a second narrower configuration after the docking device has been delivered to more securely hold the prosthetic valve. The docking device may also be better held in position at the native valve after adjustment to the narrower configuration. Some docking devices include a stabilization segment or double coil configuration, where a main coil region is configured to securely hold a prosthetic valve, while a stabilization coil region is configured to more stably hold the docking device at the native valve.Type: GrantFiled: August 23, 2017Date of Patent: June 23, 2020Assignee: Edwards Lifesciences CorporationInventors: Darshin S. Patel, Hernan Altman, Boaz Manash, Tamir S. Levi, Dinesh L. Sirimanne

Patent number: 10646361Abstract: A method of connecting an expansion ring to at least one end of a braided implant is disclosed. The method can include positioning the braided implant about a tube; everting an end portion of the braided implant over a first end of the tube; assembling an expansion ring to the braided implant, the expansion ring being a multi-leaved expansion ring including clips terminating with an open-ended coupling opening. The openings can be pushed over a set of intersecting wires of the braided implant at respective circumferential locations on or adjacent the first end of the tube. The method can also include closing the openings over the set of intersecting wire; trimming ends of the braided implant; and reversing eversion of the braided implant thereby positioning the expansion ring internal to the braided implant.Type: GrantFiled: July 30, 2019Date of Patent: May 12, 2020Assignee: DePuy Synthes Products, Inc.Inventors: Pedro Pedroso, Christopher Krier

Patent number: 10543085Abstract: A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein is disclosed, together with methods of using same. The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander.Type: GrantFiled: June 13, 2018Date of Patent: January 28, 2020Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Visith Chung, Da-Yu Chang, Brian S.

Patent number: 10478289Abstract: Apparatus for endovascularly replacing a patient's heart valve, including: a replacement valve adapted to be delivered endovascularly to a vicinity of the heart valve; an expandable anchor adapted to be delivered endovascularly to the vicinity of the heart valve; and a lock mechanism configured to maintain a minimum amount of anchor expansion. The invention also includes a method for endovascularly replacing a patient's heart valve. In some embodiments the method includes the steps of: endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve; expanding the anchor to a deployed configuration; and locking the anchor in the deployed configuration.Type: GrantFiled: August 14, 2017Date of Patent: November 19, 2019Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Amr Salahieh, Brian D. Brandt, Dwight P. Morejohn, Ulrich R. Haug, Jean-Pierre Dueri, Hans F. Valencia, Robert A. Geshlider

Patent number: 10426604Abstract: A prosthetic heart valve is designed to be circumferentially collapsible for less invasive delivery into the patient. At the implant site the valve re-expands to a larger circumferential size, i.e., the size that it has for operation as a replacement for one of the patient's native heart valves. The valve includes structures that, at the implant site, extend radially outwardly to engage tissue structures above and below the native heart valve annulus. These radially outwardly extending structures clamp the native tissue between them and thereby help to anchor the prosthetic valve at the desired location in the patient.Type: GrantFiled: April 16, 2015Date of Patent: October 1, 2019Assignee: St. Jude Medical, LLCInventor: Peter N. Braido

Patent number: 10413401Abstract: A transcatheter valve prosthesis includes an expandable tubular stent, a prosthetic valve within the stent, and an anti-paravalvular leakage component coupled to and encircling the tubular stent. The anti-paravalvular leakage component includes a radially-compressible annular scaffold, which is a sinusoidal patterned ring of self-expanding material, and an impermeable membrane extending over the annular scaffold. The anti-paravalvular leakage component has an expanded configuration in which at least segments of the annular scaffold curve radially away from the tubular stent. Alternatively, the anti-paravalvular leakage component includes a plurality of self-expanding segments and an annular sealing element coupled to inner surfaces of the segments. The anti-paravalvular leakage component has an expanded configuration in which the segments curve radially away from the tubular stent and the annular sealing element is positioned between an outer surface of the tubular stent and inner surfaces of the segments.Type: GrantFiled: February 1, 2013Date of Patent: September 17, 2019Assignee: MEDTRONIC CV LUXEMBOURG S.A.R.L.Inventors: Carol Eberhardt, Gopikrishnan Soundararajan, Kenny Dang, Hussain Rangwala

Patent number: 10314693Abstract: 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 including a plurality of struts. A cuff may be coupled to the stent so that a flat, bottom edge of the cuff lies adjacent the proximal end of the stent. A pattern of stitches may be circumferentially disposed around the flat bottom edge of the cuff, the pattern of stitches alternating between stitches sewn to the cuff only and stitches sewn to both the cuff and the stent.Type: GrantFiled: November 20, 2014Date of Patent: June 11, 2019Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Peter N.
