Patent number: 11344414Abstract: Within a delivery passage of a catheter, an elongated and flexible annuloplasty structure is transluminally advanced toward a heart of a subject while the annuloplasty structure is in a substantially linear configuration in which a distal end of the annuloplasty structure is closer than a proximal end of the annuloplasty structure to a distal opening of the catheter. Subsequently, the distal end of the annuloplasty structure is advanced, followed by the proximal end of the annuloplasty structure, out of the catheter and into an atrium of the heart. Within the atrium, the annuloplasty structure is transitioned toward a ring form by the distal end of the annuloplasty structure being brought towards the proximal end of the annuloplasty structure. While the annuloplasty structure remains in the ring form, the annuloplasty structure is placed against tissue of the annulus and is anchored to the tissue.Type: GrantFiled: April 14, 2021Date of Patent: May 31, 2022Assignee: Valtech Cardio Ltd.Inventors: Amir Gross, Iftah Beinart, Eran Miller, Oz Cabiri, Eliahu Eliachar, Nir Lilach, Ram Grossfeld, Dmitry Golom, Gideon Meyer-Brodnitz, Arnon Mosaiuf

Patent number: 11259924Abstract: Apparatuses, systems, and devices usable for annuloplasty are provided. These can include an annuloplasty system comprising a segment having a lumen therethrough, the segment being positionable in a vicinity of a surface of a heart valve of a heart. The system can include a tube having a distal portion that is movable through the lumen of the segment and a distal end passable through an opening in the segment that is in fluid communication with the lumen. One or more tissue anchors are deliverable through the tube, the tissue anchor(s) being shaped so as to define a tissue coupling element. The distal portion of the tube can be removably positioned within the lumen of the segment, and, while so positioned, to deploy the tissue coupling element from the distal end of the tube in order to penetrate the tissue coupling element into cardiac tissue. Other embodiments are also described.Type: GrantFiled: July 18, 2019Date of Patent: March 1, 2022Assignee: Valtech Cardio Ltd.Inventors: Amir Gross, Iftah Beinart, Eran Miller, Oz Cabiri, Eliahu Eliachar, Nir Lilach, Ram Grossfeld, Dmitry Golom, Gideon Meyer-Brodnitz, Arnon Mosaiuf
