ANNULOPLASTY DEVICES AND METHODS OF DELIVERY THEREFOR

摘要

A method for performing an annuloplasty includes positioning an annuloplasty ring structure along an atrial surface of an annulus of a heart valve. While a distal portion of a tube is longitudinally advanced through a channel of the ring structure, it faces a first portion of tissue of the annulus. A first tissue anchor is anchored to the first portion of tissue, from within the channel, while the distal end of the tube faces the first portion of the tissue. After moving the distal portion of the tube to a second portion of the structure, the second portion of the structure is anchored to a second portion of tissue by anchoring a second tissue anchor to the second portion of the tissue while the distal end of the tube faces the second portion of the tissue. Other embodiments are also described.
