Implantation of repair chords in the heart
First Claim
1. A method, comprising:
- advancing a distal end of an inner shaft of a delivery tool between leaflets of an atrioventricular valve of a patient and to a tissue site of a ventricle of the patient, the distal end of the inner shaft being reversibly coupled to a tissue anchor, at least a portion of the inner shaft being surrounded by a surrounding shaft coupled at a portion thereof to at least one leaflet-engaging element holder, the leaflet-engaging-element holder being shaped to define at least one coupling site for reversibly coupling at least one leaflet-engaging element to the tool;
anchoring the tissue anchor at the tissue site using the distal end of the inner shaft;
sliding the surrounding shaft of the delivery tool with respect to the distal end of the inner shaft, in a manner in which a distal portion of the surrounding shaft moves toward the leaflets, and the leaflet-engaging holder is positioned in a vicinity of at least one leaflet of the atrioventricular valve;
using the surrounding shaft, engaging at least one of the leaflets with the at least one leaflet-engaging element; and
after engaging, proximally withdrawing the distal end of the inner shaft from within the ventricle.

Abstract
Apparatus for use with at least one leaflet-engaging element, the apparatus including a delivery tool which includes an inner shaft, a surrounding shaft, and at least one leaflet-engaging element holder coupled to a portion of the surrounding shaft, the leaflet-engaging-element holder being shaped to define at least one coupling site for reversibly coupling the leaflet-engaging element to the tool. The surrounding shaft surrounds a portion of the inner shaft and is slidable along the inner shaft so as to position the leaflet-engaging holder in a vicinity of at least one leaflet of an atrioventricular valve of a patient. A distal end of the inner shaft is advanceable between leaflets of the atrioventricular valve and toward a tissue site of a ventricle of the patient. Other applications are also described.

15. Apparatus for use with a tissue anchor and at least one leaflet-engaging element, the apparatus comprising:
-
a delivery tool which comprises; an inner shaft; a surrounding shaft; and at least one leaflet-engaging element holder coupled to a portion of the surrounding shaft, the leaflet-engaging-element holder being shaped to define at least one coupling site for reversibly coupling the at least one leaflet-engaging element to the tool, wherein; the surrounding shaft surrounds a portion of the inner shaft and is slidable along the inner shaft so as to position the leaflet-engaging element holder in a vicinity of at least one leaflet of an atrioventricular valve of a patient, and a distal end of the inner shaft is (1) advanceable between leaflets of the atrioventricular valve and toward a tissue site of a ventricle of the patient, and (2) reversibly couplable to the tissue anchor. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. Apparatus for use with a sheath, which is configured to be advanced into an atrium of a patient in a transcatheter procedure, the apparatus comprising:
-
an implant assembly, which is configured to be passed through the sheath, and which comprises; at least one leaflet-engaging element; an adjustment mechanism; and at least one longitudinal member, which has opposite first and second end portions, which first end portion is coupled to the adjustment mechanism, and which second end portion is coupled to the at least one leaflet-engaging element; and a delivery tool, which is configured to be passed through the sheath, and which comprises; an inner shaft, which is configured to be advanced between leaflets of an atrioventricular valve of the patient and into a ventricle of the patient, and which is configured to be removably coupled to the adjustment mechanism, and to couple the adjustment mechanism at an intraventricular site of the ventricle; a surrounding shaft, which surrounds a portion of the inner shaft, and is slidable with respect to the inner shaft; and a coupling element holder, which is coupled to the surrounding shaft, and which is configured to couple the at least one leaflet-engaging element to at least one leaflet of the atrioventricular valve. - View Dependent Claims (40, 41)
