Patent number: 11779459Abstract: Apparatus and methods are described including a valve frame defining a frame aperture and at least one arm attached to a portion of the valve frame on a ventricular side of said frame aperture. The at least one arm is configured to extend radially from the portion of the valve frame such that a chord receiving surface of the arm is sized and shaped to deploy among a region of the chords of the native mitral valve. The arm is curved, with an interior of the arm facing a direction in which the valve frame is configured to be rotated during deployment of the prosthetic mitral valve apparatus within the native mitral valve and with the arm having a concavely rounded leading edge facing at least partially in a circumferential direction. Other applications are also described.Type: GrantFiled: June 16, 2021Date of Patent: October 10, 2023Assignee: TEL HASHOMER MEDICAL RESEARCH INFRA AND SVCS LTDInventors: Ehud Raanani, Boris Orlov, Boaz Harari, Oded Meiri, Lichen Rozitsky

Publication number: 20230172707Abstract: Apparatus and methods are described herein including an expandable prosthetic mitral valve device that includes a first component configured to be deployed in a left atrium of the subject and a second component configured to be deployed in a left ventricle of the subject. At least one approximating component approximates the first and second components with respect to each other, such that, when the first and said second components are in an approximated configuration with respect to each other, one or more leaflets of the native mitral valve are trapped within the gap between a ventricular part and an annulus part. The approximating component secures the annulus part and the ventricular part in the approximated configuration. Other applications are also described.Type: ApplicationFiled: January 31, 2023Publication date: June 8, 2023Inventors: Boris Orlov, Ehud Raanani

Publication number: 20230000622Abstract: Apparatus and methods are described including placing a valve frame within a subject's heart. The valve frame includes a valve frame body that is configured to support the prosthetic valve within the native atrio-ventricular valve, and at least one arm that is configured to extend from a ventricular portion of the valve frame. The at least one arm is deployed among chords of the native atrio-ventricular valve. Subsequently, at least a portion of the valve frame is rotated in a direction in which an interior of the arm faces, such as to modify shapes of the native valve leaflets and the ventricular structures, by recruiting and deflecting at least a portion of the chords. The frame body of the valve frame is then radially expanded, such as to hold the native valve leaflets and the ventricular structures at least partially in the modified shapes. Other applications are also described.Type: ApplicationFiled: September 14, 2022Publication date: January 5, 2023Inventors: Ehud RAANANI, Boris ORLOV, Boaz HARARI, Oded MEIRI, Lichen ROZITSKY

Publication number: 20220015905Abstract: Apparatus and methods are described for use with an annuloplasty ring (20), and an atrioventricular valve of a heart of a mammalian subject, the atrioventricular valve including a valve annulus, valve leaflets, chords, and papillary muscles. A plurality of chord-manipulation arms (26) are configured to be deployed among the chords of the atrioventricular valve, and to cause a size of the valve annulus to decrease, by the chord-manipulation arms (26) being rotated such as to twist the native atrioventricular valve and pull the native atrioventricular valve radially inwards, by the chord-manipulation arms (26) deflecting the chords. The chord-manipulation arms (26) are configured to subsequently provide a counterforce against which the annuloplasty ring (20) is pushed, during implantation of the annuloplasty ring (20). Other applications are also described.Type: ApplicationFiled: November 13, 2019Publication date: January 20, 2022Inventors: Ehud Raanani, Boris Orlov

Patent number: 10292816Abstract: A prosthetic mitral valve with a frame comprises at least one arm shaped to deploy among a region of chordae tendineae of the native mitral valve to deflect these chords in order to pull the native valve leaflets around the frame to avoid paravalvular leaks. The frame may be made from two parts that are connected by sutures. The prosthetic valve may be deployed by a catherer comprising a deployment clamp attached to the valve frame where the deployment clamp is actuable to induce rotation of the frame.Type: GrantFiled: May 20, 2013Date of Patent: May 21, 2019Assignee: TEL HASHOMER MEDICAL RESEARCH INFRASTRUCTURE AND SERVICES LTD.Inventors: Ehud Raanani, Boris Orlov, Boaz Harari, Oded Meiri, Lichen Rozitsky
