Medical kit for constricting tissue or a bodily orifice, for example, a mitral valve
First Claim
1. An implant kit, comprising:
- a plurality of tissue anchors configured to be at least partially embedded into tissue at respective locations about an orifice within a body during an implant procedure; and
an implant member reconfigurable between a delivery configuration in which the implant member is manipulable to a size and dimension to be deliverable 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 the orifice in the tissue, the implant member comprising;
a plurality of segments;
a number of pivot joints, each pivot joint comprising a respective pivot pin and a respective pivot axis, the pivot pin of each pivot joint arranged to pivotally couple each of the segments together in a respective one of a number of sets of two or more of the segments, at least one segment in each respective one of the number of sets of two or more of the segments pivoting about the respective pivot axis of the pivot joint when the implant member is moved between the delivery configuration and the deployed configuration; and
a plurality of tissue anchor receivers, each tissue anchor receiver comprising at least one alignment surface arranged to contact a portion of a respective one of the plurality of tissue anchors and align the portion of the respective one of the plurality of tissue anchors with respect to an alignment axis of the tissue anchor receiver when the respective one of the plurality of tissue anchors is secured to the implant member, the portion of the respective one of the plurality of tissue anchors impeded from moving along the alignment axis of the tissue anchor receiver to break contact with the at least one alignment surface of the tissue anchor receiver when the respective one of the plurality of tissue anchors is secured to the implant member, wherein the respective alignment axis of at least a first one of the plurality of tissue anchor receivers is non-parallel with the respective pivot axis of at least one of the number of pivot joints, and wherein the respective alignment axis of at least a second one of the plurality of tissue anchor receivers is substantially parallel to the respective pivot axis of the at least one of the number of pivot joints.

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.
