Patent number: 11819403Abstract: An expandable docking station frame includes a waist portion, a sealing portion connected to the waist portion, and a retaining portion connected to the sealing portion. The sealing portion is expandable radially outward of the waist portion to provide a seal against a first location of an inner surface of a circulatory system at a deployed position over a range of sizes of expansion. The retaining portion is expandable radially outward to engage a second location of the inner surface of the circulatory system at the deployed position, to retain the docking station at the deployed position in the circulatory system. When the expandable docking station frame is in an expanded and unconstrained state, the sealing portion and the retaining portion are joined by a concave profile portion radially inward of each of a first outermost diameter of the sealing portion and a second outermost diameter of the retaining portion.Type: GrantFiled: November 24, 2021Date of Patent: November 21, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Dustin P. Armer, Michael D. Franklin, Sergio Delgado, Abhijeet Joshi, Dinesh L. Sirimanne, Russell T. Joseph, Eason Michael Abbott, Tram Ngoc Nguyen, Son V. Nguyen, Hien Tran Ngo, Vivian Tran, Charles L.

Patent number: 11717399Abstract: An expandable stent for implantation in a right ventricular outflow tract includes a frame having a waist portion that expands to a deployed size having a first diameter, first and second sealing portions extending in opposite directions from the waist portion and expanding radially outward of the waist portion. The first and second sealing portions are sized to seal against first and second portions of the inner surface of the right ventricular outflow tract at the deployed position over a range of sizes of expansion larger than the first diameter. A band is secured to the waist portion of the frame, restricting expansion of the waist portion substantially beyond the first diameter, such that the waist portion is configured to be spaced apart from the inner surface of the right ventricular outflow tract at the deployed position.Type: GrantFiled: January 25, 2022Date of Patent: August 8, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Dustin P. Armer, Michael D. Franklin, Sergio Delgado, Abhijeet Joshi, Dinesh L. Sirimanne, Russell T. Joseph, Eason Michael Abbott, Tram Ngoc Nguyen, Son V. Nguyen, Hien Tran Ngo, Vivian Tran, Charles L.

Patent number: 11699622Abstract: A method for electrically characterizing a layer disposed on a substrate and electrically insulated from the substrate is disclosed. The method can include forming a test pattern, contacting the test pattern with electrical contact elements at contact regions, and measuring an electrical parameter of the layer by passing a first set of test currents between contact regions. The test pattern can be formed by pushing a pattern forming head against a top surface of the layer, introducing a first fluid into the cavity, and converting the sacrificial portion of the layer into an insulator using the first fluid and forming the test pattern under the test-pattern-shaped inner seal.Type: GrantFiled: March 25, 2022Date of Patent: July 11, 2023Assignee: Active Layer Parametrics, Inc.Inventors: Bulent Mehmet Basol, Jalal Ashjaee, Abhijeet Joshi

Patent number: 11596514Abstract: An expandable stent for implantation in a right ventricular outflow tract includes a frame having a plurality of struts that define a repeating pattern of cells. The repeating pattern of cells comprises a column of exactly three generally diamond shaped cells positioned in end-to-end alignment, and a column of exactly two generally diamond shaped cells positioned in end-to-end alignment. The frame has a substantially hourglass shape with a narrow portion in between a proximal end portion and a distal end portion, wherein the proximal end portion and the distal end portion are configured to expand radially outward to contact a right ventricular outflow tract.Type: GrantFiled: January 25, 2022Date of Patent: March 7, 2023Assignee: Edwards Lifesciences CorporationInventors: Dustin P.
