Implantation of repair chords in the heart
Apparatus is provided, including first and second longitudinal members coupled at respective first portions thereof to tissue surrounding the ventricle. The first portion of at least the first longitudinal member is coupled to a tissue anchor, and respective second portions of the first and second longitudinal members are coupled to respective first and second leaflets of a cardiac valve. The longitudinal members are arranged with respect to the tissue anchor and the portion of tissue surrounding the ventricle in a manner which facilitates adjustment of a degree of tension of the first and second longitudinal members to draw the first and second leaflets together. A longitudinal-member-coupling device is coupled to the first and second longitudinal members, and is advanceable toward a ventricular surface of the first and second leaflets, and responsively to draw together the first and second longitudinal members. Other applications are also described.
1. A method, comprising:
implanting a first longitudinal repair member in a ventricle of a heart of a patient, by coupling a first portion of the first longitudinal repair member to a first leaflet of a valve of the heart of the patient and by coupling a second portion of the first longitudinal repair member to tissue surrounding the ventricle;
implanting a second longitudinal repair member in the ventricle of the heart of the patient, by coupling a first portion of the second longitudinal repair member to a second leaflet of the valve of the heart of the patient and by coupling a second portion of the second longitudinal repair member to tissue surrounding the ventricle; and
advancing, toward a ventricular surface of the valve, a longitudinal-member-coupling device that is coupled to the first and second longitudinal members between the first and second portions of the respective first and second longitudinal members, and by the advancing drawing together the first and second leaflets in a middle portion of the valve.
2. The method according to claim 1 , wherein advancing comprises, by the advancing, creating first and second openings in the valve on either side of the middle portion for blood flow through the openings.
3. The method according to claim 1 , wherein the method further comprises adjusting a degree of tension of the first and second longitudinal members to adjust a degree of coupling between the first and second leaflets.
4. The method according to claim 3 , wherein adjusting the degree of tension comprises adjusting the degree of tension of the first and second longitudinal members using at least one longitudinal-member-adjusting mechanism coupled to respective second portions of the first and second longitudinal members.
