Patent number: 9345470Abstract: 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: May 14, 2013Date of Patent: May 24, 2016Assignee: Medtronic Ventor Technologies Ltd.Inventor: Yossi Tuval

Publication number: 20160089236Abstract: In some embodiments, a valve prosthesis includes an inlet portion that is substantially s-shaped and configured to engage the floor of the outflow tract of the native heart atrium. In some embodiments, a valve prosthesis includes a chordae guiding element configured to reduce bending of the chordae to reduce stress on the chordae during the cardiac cycle. In some embodiments, a valve prosthesis includes a central portion having an hourglass shape configured to pinch a native annulus in order to provide axial fixation of the valve prosthesis within a valve site. In some embodiments, a valve prosthesis includes a frame having an outflow end that is flared to provide a gap between an outflow end of the frame and an outflow end of prosthetic leaflets when the prosthetic leaflets are fully opened.Type: ApplicationFiled: December 8, 2015Publication date: March 31, 2016Inventors: Igor Kovalsky, Jason Quill, Daniel Glozman, Illia Hariton, Yossi Tuval, Nadav Yellin

Patent number: 9144493Abstract: The delivery systems disclosed herein can create simultaneous movement of an inner and an outer sheath of the delivery system. The delivery systems can generally include a handle assembly and a delivery catheter. In certain embodiments, the inner shaft and the outer sheath can be slidably controlled by a control element in the handle. The handle assembly can include a housing with a thumbwheel acting as the control element. In certain embodiments, movement of the inner shaft and the outer sheath can be caused via a gear-type system. In certain embodiments, the handle assembly can include a rotatable housing. A control element can rotate the housing, which can cause a first boss associated with the outer sheath and a second boss associated with the inner shaft to move in opposite directions.Type: GrantFiled: November 14, 2012Date of Patent: September 29, 2015Assignee: Medtronic Vascular Galway LimitedInventors: Damian Carr, Kate Corish, Niall Duffy, Ronan Rogers, Yossi Tuval, Frank White, Declan Costello, John Gallagher, James Kearns, Edmond Sheahan, Matthew Rust

Publication number: 20140379077Abstract: 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: September 12, 2014Publication date: December 25, 2014Inventors: Yossi Tuval, Raphael Benary, Ido Kilemnik

Publication number: 20140371845Abstract: 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: ApplicationFiled: August 12, 2014Publication date: December 18, 2014Inventors: Yossi Tuval, Igor Kovalsky, Ido Kilemnik, Eli Benhamou

Publication number: 20120158129Abstract: A valve retainer is connected to an elongate delivery member. The valve retainer is configured to releasably secure a prosthesis (e.g., a heart valve prosthesis) to the delivery member during delivery to a target site in a body (e.g., a native valve annulus). The valve retainer includes a rotational identifier that identifies the rotational orientation of the valve retainer when the valve retainer is positioned proximate to the target site. A heart valve prosthesis can include a commissural post that has a predetermined rotational position relative to the rotational identifier, such that the heart valve prosthesis can be rotationally aligned with the native commissures of the native valve by rotating the delivery member and the valve retainer until the commissural post is aligned with a native valve commissure and the rotational identifier is visible.Type: ApplicationFiled: December 14, 2011Publication date: June 21, 2012Inventors: Niall Duffy, Gerry McCaffrey, Noam Miller, Yossi Tuval, Daniel Glozman
