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.
