Medical device, kit and method for constricting tissue or a bodily orifice, for example, a mitral valve
First Claim
1. An implant kit comprising:
- a helical tissue anchor comprising a plurality of coils;
a percutaneous delivery system operable to at least partially embed the helical tissue anchor into a tissue insertion location in tissue within a body during an implant procedure, the percutaneous delivery system comprising a member comprising a lumen; and
a guide rail configured to provide the helical tissue anchor to the tissue insertion location, a portion of the guide rail located within at least some of the plurality of coils of the helical tissue anchor at least in a state in which the guide rail is at least partially located within the lumen of the member,wherein the guide rail comprises a bend configured to facilitate the helical tissue anchor spiraling off of the guide rail into tissue at a particular location spaced from an end of the guide rail via the helical tissue anchor rotating with respect to the guide rail.

Abstract
A device, kit and method may employ an implantable device (e.g., annuloplasty implant) and a tool to implant such. 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). Tissue anchors are guided into precise position by an intravascularly deployed anchor guide frame and embedded in an annulus. Constriction of the orifice may be accomplished via a variety of structures, for example by cinching a flexible cable or anchored annuloplasty ring, the cable or ring attached to the tissue anchors. The annuloplasty ring may be delivered in a generally elongated configuration, and implanted in an anchored generally arch, arcuate or annular configuration. Such may move a posterior leaflet anteriorly and an anterior leaflet posteriorly, improving leaflet coaptation to eliminate mitral regurgitation.

15. A method of operating a medical device, the method comprising:
-
delivering a helical tissue anchor of the medical device along a guide rail of the medical device through at least a portion of a lumen of a member of the medical device, the helical tissue anchor comprising a plurality of coils surrounding a portion of the guide rail during the delivering; and releasing the helical tissue anchor from the guide rail at least in a state in which the guide rail is partially located outside of the lumen of the member and partially located inside the lumen of the member, wherein the releasing includes a bend in the guide rail causing the helical tissue anchor to spiral off of the guide rail at a particular location spaced from an end of the guide rail in a manner configured to deliver the helical tissue anchor into tissue via the helical tissue anchor rotating with respect to the guide rail. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
