Abstract

A ringless web is configured to repair heart valve function in patients suffering from degenerative mitral valve regurgitation (DMR) or functional mitral valve regurgitation (FMR). In accordance with various embodiments, a ringless web can be anchored at one or more locations below the valve plane in the ventricle, such as at a papillary muscle, and one or more locations above the valve plane, such as in the valve annulus. A tensioning mechanism connecting the ringless web to one or more of the anchors can be used to adjust a tension of the web such that web restrains the leaflet to prevent prolapse by restricting leaflet motion to the coaptation zone and/or promotes natural coaptation of the valve leaflets.

Claims22

Dependent claims

A ringless web configured to be implanted into a beating heart of a patient to repair heart valve function, comprising:

a web configured to be chronically implanted in the beating heart of the patient without being attached to a ring and shaped and sized to correspond to at least one valve in the heart;
one or more ventricular anchors operably connected to the web and configured to be anchored in ventricular tissue in the heart, the web being a flexible material formed of a combination of a solid material and at least one open space therein and capable of conforming to aspects of native valve tissue of the beating heart the web further comprising a solid biocompatible material;
one or more atrial anchors operably connected to the web and configured to be anchored in atrial tissue in the heart;
and
a tensioning mechanism operably connected to at least one of the one or more ventricular anchors and the one or more atrial anchors, the tensioning mechanism configured to enable selective adjustment of a tension of the web with respect to the corresponding anchor such that the web is positioned across a plane of the at least one valve to repair valve function.
