Publication number: 20190239872Abstract: Devices and methods for locking and/or cutting tethers during a tissue modification procedure are described. In some variations, a tether may be used to tighten or compress tissue by bringing two pieces or sections of the tissue together. The tether, which may be under tension, may be locked to maintain the tension, and excess tether may be severed, using one or more of the devices and/or methods. The devices and/or methods may be used, for example, in minimally invasive procedures.Type: ApplicationFiled: December 5, 2018Publication date: August 8, 2019Inventors: Eugene SERINA, Tenny C. CALHOUN, Stephen C. MEIER, Mariel FABRO, Tiffany Huynh MIRCHANDANI, John TO, Brian TANG

Patent number: 9072513Abstract: Devices and methods used in termination of a tissue tightening procedure are described. Termination includes the cinching of a tether to tighten the tissue, locking the tether to maintain tension, and cutting excess tether. In procedures involving anchors secured to the tissue, the tether is coupled to the anchors and the tissue is tightened via tension applied to the anchors by cinching the tether. In general, the devices and methods can be used in minimally invasive surgical procedures, and can be applied through small incisions or intravascularly. A method for tightening tissue by fixedly coupling a first anchor to a tether and slidably coupling a second anchor to the tether, securing both anchors to the tissue, applying tension to the tether intravascularly, fixedly coupling the tether to the second anchor, and cutting the tether is described. The tissue to be tightened can comprise heart tissue, in particular heart valve annulus tissue.Type: GrantFiled: August 6, 2008Date of Patent: July 7, 2015Assignee: Guided Delivery Systems Inc.Inventors: John To, Niel F. Starksen, Tenny C. Calhoun, Brian Tang

Patent number: 8795298Abstract: Devices, methods, and kits for tensioning tethers during a tissue modification procedure are described. In some variations, a tether coupled to anchors embedded in tissue may be tensioned to provide a cinching effect that tightens or compresses the tissue by bringing two pieces or sections of the tissue together. In certain variations, the tether may then be locked (e.g., to maintain the tension), and/or excess tether may be severed. The devices, methods, and/or kits may be used, for example, in minimally invasive procedures.Type: GrantFiled: October 9, 2009Date of Patent: August 5, 2014Assignee: Guided Delivery Systems Inc.Inventors: Jonathan D. Hernlund, Tenny C. Calhoun, Brian Tang, John To, Clyde Henry Booth, III

Publication number: 20080177380Abstract: Methods for securing implants to heart tissue are described, where the implants include one or more anchor portions extending from a support. Some variations of the methods may comprise securing an implant to a first region of a tissue in the vicinity of a subannular groove of a heart, where the implant comprises a support and a first anchor portion extending from a first portion of the support. The implant may further comprise a second anchor portion extending from a second portion of the support. Certain variations of the methods may include advancing a catheter to a first region of a tissue in the vicinity of a subannular groove of a heart, and deploying an implant from the catheter to the first region of tissue, where the implant comprises a support and a first anchor portion extending from a first portion of the support. Implants also are described.Type: ApplicationFiled: January 19, 2007Publication date: July 24, 2008Inventors: Niel F. Starksen, Mariel Fabro, Karl S. Im, Tenny C. Calhoun
