Publication number: 20170209270Abstract: A method is provided including inserting into a heart a tissue-adjusting member selected from the group consisting of: one or more artificial chordae tendineae and an annuloplasty ring structure. An adjusting mechanism of the tissue-adjusting member adjusts tension of the tissue-adjusting member. The adjusting mechanism: (a) includes a locking mechanism configured to restrict adjusting of the tissue-adjusting member by the adjusting mechanism, and (b) is shaped to define a first coupling. The method further includes, using a tool reversibly coupled to the adjusting mechanism, restricting the adjusting of the tissue-adjusting member by the adjusting mechanism, by facilitating movement of the locking mechanism into a locked state. The tool is shaped to define a second coupling that mates with the first coupling of the adjusting mechanism. The first and second couplings are coupled together and remain mated during the restricting of the adjusting of the tissue-adjusting member.Type: ApplicationFiled: March 20, 2017Publication date: July 27, 2017Applicant: VALTECH CARDIO, LTD.Inventors: Eran MILLER, Uriel Aba POMERANTZ, Oz CABIRI, Yaron HERMAN, Yoseph WEITZMAN, Yossi GROSS

Patent number: 8911494Abstract: An anchor driver is provided that includes a driver head having a flexible ring. An anchor is provided that includes a coupling head, which is shaped so as to define: (a) one or more mating elements that engage mechanical coupling elements of the driver head such that rotation of the mechanical coupling elements rotates the mating elements, which in turn rotate the coupling head, and (b) an outer coupling surface, sized to be inserted into and engage the flexible ring. The anchor also includes a tissue coupling element fixed to the coupling head. The rotation of the mechanical coupling elements causes the tissue coupling element of the anchor to screw itself into tissue, thereby causing separation of: (a) the outer coupling surface of the coupling head from the flexible ring, and (b) the mating elements of the coupling head from the corresponding mechanical coupling elements. Other embodiments are also described.Type: GrantFiled: January 19, 2010Date of Patent: December 16, 2014Assignee: Valtech Cardio, Ltd.Inventors: Tal Hammer, Yuval Zipory, Yoseph Weitzman, Amir Gross, Oz Cabiri, Aram Ayvazian
