Patent number: 11844665Abstract: 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: GrantFiled: January 24, 2020Date of Patent: December 19, 2023Assignee: Edwards Lifesciences Innovation (Israel) Ltd.Inventors: Yuval Zipory, Oz Cabiri, Yosef Gross, Tal Hammer, Amir Gross, Francesco Maisano, Eran Miller, Yoseph Weitzman, Aram Ayvazian

Patent number: 10548729Abstract: An implant structure includes a contracting mechanism, including a rotatable structure for contracting the implant structure, and a locking mechanism. A rotation tool is configured to engage and rotate the rotatable structure. A longitudinal guide member is removably coupled to the contracting mechanism, configured to guide the rotation tool to the rotatable structure, and includes a distal force applicator. The rotation tool is axially moveable with respect to the guide member. The contracting mechanism is arranged such that the locking mechanism is (a) unlocked when the guide member is coupled to the contracting mechanism in a first state, thereby allowing the rotatable structure to rotate, and (b) locked when (i) the guide member is coupled to the contracting mechanism in a second state, thereby restricting the rotation of the rotatable structure, and (ii) the guide member is not coupled to the contracting mechanism, thereby restricting the rotation of the rotatable structure.Type: GrantFiled: March 30, 2017Date of Patent: February 4, 2020Assignee: Valtech Cardio, Ltd.Inventors: Yuval Zipory, Oz Cabiri, Yossi Gross, Tal Hammer, Amir Gross, Francesco Maisano, Eran Miller, Yoseph Weitzman, Aram Ayvazian

Patent number: 9636224Abstract: Apparatus is provided for use with a subject, including an implant comprising a sleeve shaped so as to define a lumen therein, the sleeve having first and second portions. A contracting mechanism is coupled to a portion of an outer surface of the sleeve in a vicinity of the first portion of the sleeve. An elongated contracting member is coupled at a first end portion thereof to the contracting mechanism, and coupled at a second end portion thereof to the sleeve in a vicinity of the second portion of the sleeve. The contracting mechanism comprises a driving interface that is positioned so as to be accessible from the portion of the outer surface of the sleeve. The contracting mechanism is configured such that rotation of the driving interface contracts the implant by tightening the elongated contracting member. Other applications are also described.Type: GrantFiled: May 4, 2010Date of Patent: May 2, 2017Assignee: VALTECH CARDIO, LTD.Inventors: Yuval Zipory, Oz Cabiri, Tal Hammer, Aram Ayvazian

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
