Publication number: 20200188111Abstract: In some examples, the disclosure describes annuloplasty devices, systems, and methods involving one or more flexible elongated elements attached to one or more anchors secured proximate an annulus of a cardiac or vascular valve. In some examples one or more anchors are proximate a first side of a valve annulus. One or more flexible elements attached to the anchors are tightened to pull the first side closer to a second side of the annulus, thus reducing a dimension of the annulus. In some examples, an annuloplasty system includes an annuloplasty ring and one or more anchors configured to attach the ring proximate a valve annulus. The ring may include permanently deformable section that can be deformed after implantation to change a dimension of a corresponding valve annulus.Type: ApplicationFiled: December 11, 2019Publication date: June 18, 2020Inventors: Olivia Metcalf, Matthew E.
