Abstract

Apparatus is provided that includes first and second tissue-engaging elements, and first and second flexible longitudinal members, coupled at respective first end portions thereof to the first and the second tissue-engaging elements, respectively. The apparatus further includes a first flexible-longitudinal-member-coupling element coupled to a second end portion of the first flexible longitudinal member, a second flexible-longitudinal-member-coupling element coupled to a second end portion of the second flexible longitudinal member, and a flexible longitudinal guide member reversibly coupled to the first flexible-longitudinal-member-coupling element. The first and second flexible-longitudinal-member-coupling elements are configured to be couplable together to couple together the first and the second flexible longitudinal elements. Other applications are also described.

wherein the first and second flexible-longitudinal-member-coupling elements are configured to be couplable together to couple together the first and the second flexible longitudinal elements.

4 more elements

A method comprising:

implanting, in tissue of an atrium of a patient, a first tissue-engaging element, to which a first end portion of a first flexible longitudinal member is coupled, while a flexible longitudinal guide member is reversibly coupled to a first flexible-longitudinal-member-coupling element that is coupled to a second end portion of the first flexible longitudinal element, wherein the first and the second end portions of the first flexible longitudinal member are disposed at opposite longitudinal ends of the first flexible longitudinal member;
advancing, over the flexible longitudinal guide member, toward the atrium, a second flexible-longitudinal-member-coupling element coupled to a second end portion of a second flexible longitudinal member, wherein a second tissue-engaging element is coupled to a first end portion of the second flexible longitudinal member, and the first and the second end portions of the second flexible longitudinal member are disposed at opposite longitudinal ends of the second flexible longitudinal member;
coupling together the first and the second flexible-longitudinal-member-coupling elements;
and
implanting the second tissue-engaging element upstream of the atrium.
