Publication number: 20200163763Abstract: A first part of an annuloplasty structure is anchored to an annulus of a valve of a heart by using a driver to screw a tissue-coupling element of a first anchor into a first site of the annulus, such that the tissue-coupling element enters cardiac tissue in a direction parallel to a central longitudinal axis of the driver through the distal end of the anchor driver. The same is subsequently done for second and third parts of the annuloplasty structure using second and third anchors at second and third sites of the annulus, mutatis mutandis. Between anchors, the driver is retracted out of the heart. Subsequently, the valve is treated by reducing a distance between the first site and the second site, and a distance between the second site and the third site, by tightening a flexible and elongate contracting member of the annuloplasty structure.Type: ApplicationFiled: January 24, 2020Publication date: May 28, 2020Inventors: Yuval Zipory, Oz Cabiri, Yosef Gross, Tal Hammer, Amir Gross, Francesco Maisano, Eran Miller, Yoseph Weitzman, Aram Ayvazian

Publication number: 20200163764Abstract: Devices and related methods of use are provided for improving heart function. In one embodiment of the present disclosure, a device includes a ring-like structure configured to be secured to a heart valve; at least one elongate member extending from the ring-like structure, wherein an end of the elongate member is configured to be secured to heart geometry other than a heart valve; and an adjustment mechanism for simultaneously altering a dimension of the ring-like structure and a length of the elongate member.Type: ApplicationFiled: January 31, 2020Publication date: May 28, 2020Inventors: Donald E. Bobo, JR., Assaf Bash, Louis A. Campbell, Alison S. Curtis, Tak G. Cheung, John F. Migliazza

Publication number: 20200163765Abstract: A prosthetic heart valve can include an outer support assembly, an inner valve assembly, which define between them an annular space, and a pocket closure that bounds the annular space to form a pocket in which thrombus can be formed and retained. Alternatively, or additionally, the outer support assembly and the inner valve assembly can be coupled at the ventricle ends of the outer support assembly and the inner valve assembly, with the outer support assembly being relatively more compliant in hoop compression in a central, annulus portion than at the ventricle end, so that the prosthetic valve can seat securely in the annulus while imposing minimal loads on the inner valve assembly that could degrade the performance of the valve leaflets.Type: ApplicationFiled: January 30, 2020Publication date: May 28, 2020Applicant: Tendyne Holdings, Inc.Inventors: Mark Christianson, Chad Perrin, Zachary Tegels, Craig Ekvall, Robert Vidlund, Son Mai, Michael Evans

Publication number: 20200163766Abstract: Apparatus is provided for use with a guidewire, the apparatus including a tissue anchor, and a tool for facilitating implanting of the tissue anchor. The tool includes a sheath, and an atraumatic tip, which is removably engaged to a distal end of the sheath, and which is shaped so as to define a body that defines a recess for housing the tissue anchor during guiding of the tool through vasculature of a patient.Type: ApplicationFiled: January 17, 2019Publication date: May 28, 2020Applicant: 4Tech Inc.Inventor: Idan Tobis
