Medical kit for constricting tissue or a bodily orifice, for example, a mitral valve
First Claim
1. An implant, comprising:
- an implant member reconfigurable between a delivery configuration in which the implant member is manipulable to a size and dimension to be delivered percutaneously to the tissue within the body, and a deployed configuration in which the implant member forms a structure sufficiently rigid to affect a shape of an orifice in the tissue, the implant member comprising;
a plurality of segments;
a pivot joint comprising a pivot axis, the pivot joint arranged to pivotally couple two segments of the plurality of segments together; and
a holder activatable between a free configuration in which the two segments are arranged to pivot towards and away from each other about the pivot axis, and a fixed configuration in which the two segments are impeded from pivoting towards and away from each other about the pivot axis with a greater resistance than when the holder is in the free configuration, the holder comprising a plurality of interlockable elements positioned in interlocked engagement when the holder is in the fixed configuration, wherein a first one of the two segments is impeded with a first resistance from pivoting about the pivot axis along a first rotational direction towards a second one of the two segments when the holder is in the fixed configuration, and the first one of the two segments is impeded with a second resistance from pivoting about the pivot axis along a second rotational direction away from the second one of the two segments when the holder is in the fixed configuration, wherein the second rotational direction is opposite to the first rotational direction, each of the first resistance and the second resistance is provided at least in part by the holder, and a magnitude of the second resistance is less than a magnitude of the first resistance.

Abstract
A device, kit and method may include or employ an implantable device (e.g., annuloplasty implant) and a plurality of tissue anchors. The implantable device is positionable in a cavity of a bodily organ (e.g., a heart) and operable to constrict a bodily orifice (e.g., a mitral valve). Each of the tissue anchors may be guided into precise position by an intravascularly or percutaneously techniques. Constriction of the orifice may be accomplished via a variety of structures, for example an articulated annuloplasty ring, the ring attached to the tissue anchors. The annuloplasty ring may be delivered in an unanchored, generally elongated configuration, and implanted in an anchored generally arched, arcuate or annular configuration. Such may approximate the septal and lateral (clinically referred to as anterior and posterior) annulus of the mitral valve, to move the posterior leaflet anteriorly and the anterior leaflet posteriorly, thereby improving leaflet coaptation to reduce mitral regurgitation.
