Systems and methods for delivery of annuloplasty rings
First Claim
1. A system for percutaneous, transcatheter heart valve repair, the system comprising:
- a catheter configured to provide percutaneous access into a heart of a patient;
an adjustable annuloplasty ring comprising;
a body member that is transitionable from an elongate insertion geometry to an annular operable geometry, the elongate insertion geometry configured to allow percutaneous passage of the annuloplasty ring, via the catheter, into the heart of a patient, and the annular operable geometry having an expanded state to conform to an annulus of a target valve of the heart and a contracted state to reduce a diameter of the annulus of the target valve,a plurality of anchors deployable in the annular operable geometry to engage the annulus of the target valve; and
a stabilizer comprising a plurality of prongs configured to engage the annuloplasty ring after the body member has transitioned into the annular operable geometry within the heart to enable percutaneous manipulation of the ring to orient and position the ring in intimate contact with the annulus of the target valve.

Abstract
Systems and methods for percutaneous, transcatheter heart valve repair are disclosed. A system may include a catheter, an adjustable ring, and a stabilizer. The adjustable ring may include a body member that is transitionable from an insertion geometry to an operable geometry. The insertion geometry may be configured to allow percutaneous passage of the ring into the heart. The operable geometry may have an expanded state to conform to an annulus of a target valve and a contracted state to reduce a diameter of the annulus. The adjustable ring may also include a plurality of anchors deployable in the operable geometry to engage the annulus. The stabilizer may include a plurality of prongs configured to engage the ring in the operable geometry within the heart to enable percutaneous manipulation of the ring to orient and position the ring in intimate contact with the annulus.

12. A method for percutaneous, transcatheter heart valve repair, the method comprising:
-
inserting a distal end of a catheter into a target valve; guiding, via a delivery system, an annuloplasty ring in an elongate geometry from a proximal end of the catheter to the distal end such that the annuloplasty ring transitions to an annular operable geometry upon exiting the distal end of the catheter; orienting, via a stabilizer portion of the delivery system, the annuloplasty ring in intimate contact with the annulus of the target valve prior to deploying a plurality of anchors, wherein the stabilizer portion of the delivery system engages the annuloplasty ring after transitioning into the annular operable geometry; and deploying a plurality of anchors from the annuloplasty ring to engage an annulus of the target valve. - View Dependent Claims (13, 14, 15, 16, 17, 18)
