Patent number: 12508129Abstract: A system for use at an annulus of a valve of a heart of a subject comprises an implant and an implant-positioning device. The implant comprises (i) a wire; (ii) multiple anchors, slidably mounted in series along the wire, each of the anchors having: a slot through which the wire is threaded, and a pointy front end; and (iii) multiple tubes, the wire being threaded through each of the tubes such that the multiple tubes are slidably mounted on the wire alternatingly with the multiple anchors. The implant-positioning device is configured to implant the implant in the heart with the wire positioned along the annulus by, for each of the anchors: (i) positioning the anchor at the annulus, and (ii) using a deployment mechanism of the implant-positioning device, driving the pointy front end of the anchor into the annulus.

Patent number: 12458497Abstract: A method of treating a native mitral valve without open-heart surgery is disclosed. An expandable prosthesis includes an anchoring portion and an occluding member coupled to the anchoring portion. The prosthesis is loaded into a distal end portion of a delivery catheter and is advanced through a femoral vein and through a pre-made puncture in an atrial septum. The anchoring portion self-expands within the left atrium for anchoring the occluding member in a fixed position. The anchoring portion is preferably a laser cut structure that conforms to the left atrium and uniformly distributes anchoring forces within the left atrium. After deployment, the occluding member prevents blood from flowing from the left ventricle to the left atrium during systole. The occluding member is preferably made from a flexible material, such as pericardial tissue.Type: GrantFiled: June 22, 2020Date of Patent: November 4, 2025Assignee: Edwards Lifesciences AGInventors: Avraham Zakay, David Mishaly, Dan Rottenberg, David Alon

Publication number: 20250177142Abstract: Mitral valve regurgitation can be ameliorated by creating one passageway between the right atrium and the left ventricle at a portion of the tricuspid annulus that is directly above the interventricular septum and creating another passageway through an outer wall of the left ventricle near at least one of the left-ventricular papillary muscles. A first support member is positioned within the right atrium in contact with a septal portion of the tricuspid annulus, and a support plate is positioned against the outer wall of the left ventricle adjacent to the second passageway. The support plate is pulled towards the first support member using a tether under tension that runs between the first support plate and the first support member and passes through both passageways. And the tension in the tether moves the roots of the chordae closer to the mitral valve, which ameliorates the mitral valve regurgitation.Type: ApplicationFiled: December 6, 2024Publication date: June 5, 2025Inventor: David ALON

Patent number: 12023247Abstract: A device (e.g., an annulus-constricting device) with N anchors may be affixed to a cardiac valve annulus as follows. First, the device is delivered to the vicinity of the annulus via a catheter. Next, the position and layout of the device is adjusted via the catheter. Next, only those anchors which are properly positioned are driven into the annulus or tissue adjacent to the annulus. The remaining anchors remain unlaunched at this point. The unlaunched anchors are subsequently moved into a good position using either a manipulating tool or catheter-steering techniques, after which they are driven into the annulus or tissue adjacent to the annulus.Type: GrantFiled: May 18, 2021Date of Patent: July 2, 2024Assignee: EDWARDS LIFESCIENCES CORPORATIONInventor: David Alon

Publication number: 20240024109Abstract: An implant may be affixed to a cardiac valve annulus by an apparatus that includes a catheter with a first actuatable bending section and a support structure affixed to the distal end of the catheter. Support arms extend distally beyond the support structure. In some embodiments, a shaft with a second actuatable bending section is permanently positioned between the support arms, and an inflatable balloon surrounds at least a portion of the shaft. In other embodiments, a subassembly that includes a shaft with a second actuatable bending section and an inflatable balloon is slidably mounted so that it can move from an initial position that is spaced apart from the support structure to a second position where the balloon is between the at least four support arms. In either case, actuating the second bending section when the balloon is inflated will move the support arms that support the implant.Type: ApplicationFiled: February 14, 2023Publication date: January 25, 2024Inventors: David ALON, Dmitry PINHASOV
