Patent attributes
Apparatus is provided for use at a native atrioventricular valve of a heart of a subject. A prosthetic valve structure includes prosthetic leaflets configured to facilitate upstream-to-downstream bloodflow longitudinally through the prosthetic valve structure. The apparatus includes an annular portion configured to be positioned at the native atrioventricular valve and curved anchors that point in a circumferential direction around the annular portion. The anchors each having a leading tip configured to gather chordae tendineae of the heart between the anchors and the annular portion. Rotation of the prosthetic valve structure in the circumferential direction causes the anchors to gather the chordae tendineae between the anchors and the annular portion by the anchors moving, leading tip first, in the circumferential direction. Other embodiments are also described.
