Publication number: 20200038186Abstract: An annuloplasty implant is provided for treating a native atrioventricular valve of a patient, the annuloplasty implant including a plurality of tissue anchors, which are configured to anchor the annuloplasty implant around at least a portion of a valve annulus of the native atrioventricular valve. The annuloplasty further includes a contracting assembly, which includes an elongate contracting member; and a contracting mechanism, which is coupled to the elongate contracting member, and which is configured, upon actuation thereof, to apply a longitudinal contracting force to the elongate contracting member that longitudinally contracts at least a portion of the annuloplasty implant, thereby circumferentially tightening the valve annulus. The annuloplasty further includes a force-distributing element, which includes a longitudinally-non-compressible tightly-coiled element, and which is configured to distribute the longitudinal contracting force over at least two of the tissue anchors.Type: ApplicationFiled: October 14, 2019Publication date: February 6, 2020Inventors: Amir Gross, Tal Sheps, Tal Hammer, Tal Reich, Ehud Iflah, Yaron Herman, Uriel Aba Pomerantz, Oz Cabiri

Patent number: 10492909Abstract: 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: GrantFiled: March 20, 2017Date of Patent: December 3, 2019Assignee: Valtech Cardio, Ltd.Inventors: Eran Miller, Uriel Aba Pomerantz, Oz Cabiri, Yaron Herman, Yoseph Weitzman, Yossi Gross

Patent number: 10470882Abstract: During a percutaneous procedure, a flexible sleeve of an annuloplasty structure is introduced into an atrium and arranged completely around an annulus as a closed loop, such that none of one or more longitudinal contracting members thereof is positioned along an anterior portion of the annulus between fibrous trigones of the valve. The annuloplasty structure is fastened to the annulus. At least a portion of a posterior portion of the annulus is tightened, while preserving a length of an anterior portion of the annulus between fibrous trigones of the valve, by contracting, using the one or more longitudinal contracting members, a longitudinal portion of the sleeve not positioned along the anterior portion of the annulus between the fibrous trigones of the valve. Thereafter, the one or more longitudinal contracting members are locked.Type: GrantFiled: March 30, 2017Date of Patent: November 12, 2019Assignee: Valtech Cardio, Ltd.Inventors: Amir Gross, Tal Sheps, Tal Hammer, Tal Reich, Ehud Iflah, Yaron Herman, Uriel Aba Pomerantz, Oz Cabiri

Publication number: 20170014954Abstract: Disclosed herein are methods, systems, and materials for high resolution three dimensional printing of metals using low cost raw material. The method employs masked brazing foils having structural layers, melting layers, and in some embodiments masking layers. The foils are selectively joined by brazing to form three dimensional metal objects. Some of the embodiments differ in the number of structural and/or melting layers in the foils, how masks are formed, and how many brazing steps are employed. Etching removes foil material that is not to remain as part of the final three dimensional object, and various embodiments are disclosed for applying the etchant.Type: ApplicationFiled: July 17, 2016Publication date: January 19, 2017Inventors: Uriel Aba Pomerantz, Itzhak Pomerantz
