Publication number: 20210205075Abstract: 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: ApplicationFiled: March 24, 2021Publication date: July 8, 2021Inventors: Carol EBERHARDT, Gopikrishnan SOUNDARARAJAN, Kenny DANG, Hussain RANGWALA, Mark TORRIANNI, Eric RICHARDSON, Kshitija GARDE

Patent number: 10299916Abstract: A method of reinforcing or repairing a bioprosthetic tissue for use as a prosthetic valve leaflet. The method includes evaluating a bioprosthetic tissue, identifying a defect in the bioprosthetic tissue, and selectively applying an adhesive to a surface of the bioprosthetic tissue at the defect prior to implantation in a patient.Type: GrantFiled: December 19, 2016Date of Patent: May 28, 2019Assignee: Medtronic Vascular, Inc.Inventors: Tracey Tien, Carol Eberhardt, Kshitija Garde, Benjamin Wong, Wei Wang, Elliot Howard, Laura McKinley, Karl Olney, Taylor Winters

Patent number: 10058421Abstract: A prosthetic stented heart valve which includes a compressible and expandable stent structure having first and second opposite ends, an expanded outer periphery, and a compressed outer periphery that is at least slightly smaller than the expanded outer periphery when subjected to an external radial force. The valve further includes a valve segment comprising a dual-layer sheet formed into a generally tubular shape having at least one longitudinally extending seam, and a plurality of leaflets formed by attachment of an outer layer of the dual-layer sheet to an inner layer of the dual-layer sheet in a leaflet defining pattern. The valve segment is at least partially positioned within the stent structure. The valve may further include at least one opening in the outer layer of the dual-layer sheet that is spaced from both the first and second ends of the stent structure.Type: GrantFiled: April 18, 2016Date of Patent: August 28, 2018Assignee: Medtronic, Inc.Inventors: Carol Eberhardt, Janice Shay

Patent number: 9101467Abstract: Heart valve prostheses are provided having a self-expanding frame that supports a valve body comprising a plurality of coapting leaflets. The valve body may include a first leaflet, a second leaflet, and a third leaflet, wherein the second leaflet extends between the first leaflet and the third leaflet such that the first and third leaflets are separated from each other by the second leaflet. The leaflets are constructed with four commissure points to reduce the stress and strain applied to the commissure points and to efficiently distribute forces along the leaflets and to the frame. As such, the first and second leaflets may be sewn together to form a first commissure point and a second commissure point, and the second and third leaflets may be sewn together to form a third commissure point and a fourth commissure point, with the four commissure points being sewn to the frame.Type: GrantFiled: March 30, 2012Date of Patent: August 11, 2015Assignee: Medtronic Cv Luxembourg S.a.r.l.Inventors: Carol Eberhardt, Tomas McNatt, Pham Lo
