Patent ID: 8790394

Claim:
Apparatus for use with a heart of a subject, the apparatus comprising an implant, the implant comprising: an implantable artificial-chordeae-tendineae-adjustment mechanism, configured to be coupled to tissue that faces a ventricle of the heart of the subject; at least one primary artificial chordea tendinea coupled at a distal portion thereof to the artificial-chordeae-tendineae-adjustment mechanism such that a degree of tension of the at least one primary artificial chordea tendinea is adjustable by the artificial-chordeae-tendineae-adjustment mechanism; one or more loops coupled at a proximal portion of the at least one primary artificial chordea tendinea, the one or more loops being configured to facilitate suturing of the one or more loops to respective portions of a leaflet of an atrioventricular valve of a patient; and an anchor, configured to be coupled to tissue of the heart, and to be coupled, via the implantable artificial-chordeae-tendineae-adjustment mechanism, to the at least one primary artificial chordea tendinea, wherein: the artificial-chordeae-tendineae-adjustment mechanism comprises a spool, the at least one primary artificial chordea tendinea is coupled to the spool, and the spool is bidirectionally rotatable to adjust the degree of tension of the at least one primary artificial chordea tendinea.
