Patent number: 11751993Abstract: Apparatus and methods are provided, including a plurality of anchoring elements, each of the anchoring elements being an elongate element that is curved to define an opening. A housing holds each of the anchoring elements. A mandrel is reversibly disposable through the openings defined by the anchoring elements. The anchoring elements are configured such that, in response to removal of the mandrel from the openings, ends of the anchoring elements automatically move outwardly, and diameters of the openings decrease, due to elastic loading of the anchoring elements. Other embodiments are also described.Type: GrantFiled: January 8, 2020Date of Patent: September 12, 2023Assignee: Medtronic Ventor Technologies Ltd.Inventor: Yossi Tuval

Patent number: 11602430Abstract: A prosthesis for implantation at a native semilunar valve includes a prosthetic distal valve, which includes a pliant material configured to collapse inwardly towards a longitudinal axis of the prosthesis during diastole, and to open outwardly during systole, and a distal fixation member configured to be positioned in a downstream artery of the subject. The apparatus also includes a proximal fixation member coupled to the distal fixation member, and configured to be positioned at least partially on a ventricular side of the native semilunar valve. The proximal fixation member is shaped so as to define a lattice that is shaped so as to define an intermediary portion that is coupled to the pliant material of the valve and diverges outwardly from the longitudinal axis, and a distal portion that is distal to the intermediary portion and diverges outwardly from the intermediary portion of the lattice. Other embodiments are also described.Type: GrantFiled: December 7, 2020Date of Patent: March 14, 2023Assignee: Medtronic Ventor Technologies Ltd.Inventors: Yossi Tuval, Igor Kovalsky, Ido Kilemnik, Eli Benhamou

Publication number: 20220296368Abstract: A prosthesis is provided for implantation at a native semilunar valve of a native valve complex, the native valve complex having three semilunar sinuses and three native commissures. The prosthesis includes a valve prosthesis support, which comprises a support structure comprising exactly three engagement arms that meet one another at three respective junctures. The engagement arms are shaped so as define three peak complexes at the three respective junctures, and three trough complexes, each of which is between two of the peak complexes. Upon implantation of the prosthesis, each of the engagement arms is at least partially disposed within a respective one of the semilunar sinuses, such that each of the peak complexes is disposed distal to and in rotational alignment with a respective one of the native commissures, and each of the trough complexes is disposed at least partially within the respective one of the semilunar sinuses.Type: ApplicationFiled: June 6, 2022Publication date: September 22, 2022Inventors: Yossi Tuval, Raphael Benary, Ido Kilemnik
