Abstract: During a percutaneous transcatheter procedure, an annuloplasty structure is secured at least partially around an annulus of a mitral valve of a subject by coupling a plurality of tissue anchors to the annulus such that (i) a longitudinal contracting member of the annuloplasty structure extends at least partially around the annulus, and (ii) the plurality of tissue anchors is distributed at least partially around the annulus. A longitudinal density of the anchors along a middle scallop of a posterior leaflet of the mitral valve is at least twice as great as a longitudinal density of the anchors along a lateral scallop of the posterior leaflet, and/or at least twice as great as a longitudinal density of the anchors along a medial scallop of the posterior leaflet. Thereafter, at least part of the annulus is contracted by contracting a longitudinal portion of the annuloplasty structure by tightening the longitudinal contracting member.

Abstract: An implant structure, comprises a body portion, a first adjusting mechanism, and a second adjusting mechanism. The body portion is configured to be secured around an annulus of a native valve of a heart of a patient. The first adjusting mechanism is coupled to a first portion of the body portion, and comprises a first ring that surrounds the first portion and is moveable with respect to the body portion. The second adjusting mechanism is coupled to a second portion of the body portion, and comprises a second ring that surrounds the second portion and is moveable with respect to the body portion. A first elongate tool is configured to remodel tissue of the heart by actuating the first adjusting mechanism. A second elongate tool is configured to remodel tissue of the heart by actuating the second adjusting mechanism.
