HEART AND PERIPHERAL VASCULAR VALVE REPLACEMENT IN CONJUNCTION WITH A SUPPORT RING
First Claim
1. An implantable valve system comprising:
- an adjustable stabilizing ring comprising;
a body member that is transitionable from an elongate insertion geometry to an annular operable geometry, anda plurality of anchors deployable in the annular operable geometry to engage the annulus of a cardiovascular valve; and
an implantable valve frame in mechanical communication with the adjustable stabilizing ring,wherein the elongate insertion geometry is configured to allow percutaneous passage of the stabilizing ring, via a catheter, to a position adjacent to an annulus of the cardiovascular valve, andwherein the annular operable geometry has a closed state to conform to the annulus of the cardiovascular valve.

Abstract
An implantable valve replacement system for a cardiovascular valve may include an adjustable stabilizing ring. The stabilizing ring may be composed of a body member that is transitionable from an elongate insertion geometry to an annular operable geometry. The stabilizing ring may further include a plurality of anchors deployable in the annular operable geometry to engage the annulus of the cardiovascular valve. The ring may be used in conjunction with an implantable valve frame. The valve frame may be located within the ring and the ring, in turn, may be stabilized through the anchors engaging the valve annulus. The valve replacement system may be applied by engaging the ring in its annular operable geometry with the valve annulus through the anchors. The valve frame may be inserted through the opening of the ring, thereby forming a stabilizing mechanical contact between the frame and the annulus.

27. A platform to stabilize an implantable valve frame, the platform comprising:
-
an adjustable stabilizing ring comprising; a body member that is transitionable from an elongate insertion geometry to an annular operable geometry, and a plurality of anchors deployable in the annular operable geometry to engage the annulus of a cardiovascular valve, wherein the elongate insertion geometry is configured to allow percutaneous passage of the stabilizing ring, via a catheter, to a position adjacent to an annulus of the cardiovascular valve, wherein the annular operable geometry has a closed state to conform to the annulus of the cardiovascular valve, and wherein the adjustable stabilizing ring in the closed state of the annular operable geometry is configured to receive and stabilize the implantable valve frame at a position proximal to the annulus of the cardiovascular valve. - View Dependent Claims (29, 30, 31, 33)

34. A method of stabilizing a replacement of a cardiovascular valve, the method comprising:
-
inserting a distal end of a catheter comprising a delivery system into the cardiovascular valve; guiding, via the delivery system, an adjustable stabilizing ring in an elongate geometry from a proximal end of the catheter to the distal end such that the adjustable stabilizing ring transitions to an annular operable geometry upon exiting the distal end of the catheter; deploying a plurality of anchors from the adjustable stabilizing ring to engage an annulus of the cardiovascular valve; guiding an implantable valve frame comprising the replacement of the cardiovascular valve through the cardiovascular valve and through a center of the adjustable stabilizing ring; and engaging at least a portion of the implantable valve frame with the adjustable stabilizing ring, thereby stabilizing a position of the implantable valve frame with respect to the cardiovascular valve. - View Dependent Claims (35, 37)
