LEAFLET RESTRAINTS

A leaflet restraint (20) includes a non-blood-occlusive net (30), which is configured to at least partially cover an atrial surface (32) of a single native cardiac leaflet (34) of a native atrioventricular valve (36) of a heart (38). Two or more tissue-penetrating annulus anchors (40) are fixed to a...

More Information
Summary:A leaflet restraint (20) includes a non-blood-occlusive net (30), which is configured to at least partially cover an atrial surface (32) of a single native cardiac leaflet (34) of a native atrioventricular valve (36) of a heart (38). Two or more tissue-penetrating annulus anchors (40) are fixed to an annular side (42) of the net (30), and are configured to be anchored to an annulus (44) of the native atrioventricular valve (36) along or within 1 cm of a portion of the annulus (44) to which the single native cardiac leaflet (34) attaches. A ventricular anchor (50) is configured to be anchored to a ventricle (54) of the heart (58) so as to anchor a ventricular end (52) of the net (30) to the ventricle (54). The leaflet restraint (20) is configured, when anchored in place at least partially covering the atrial surface (32) of the single native cardiac leaflet (34), to limit prolapse of the single native cardiac leaflet (34) into an atrium (56) of the heart (38). Other embodiments are also described.
